1.1.1
Scope and Organization
Organization
This document is intended to help a programmer understand the details of the operation of the ADV7511. It is divided into
sections:
▶
▶
▶
▶
1.1.2
Section 2 -References- is a list of other references, which will be helpful when designing with the HDMI Transmitter.
Section 3 -Quick Start Guide- provides a reference to commonly used registers divided by function.
Section 4 -Programming Tasks- is divided into common programming tasks. This section includes references to
registers and detailed descriptions of the method to accomplish the task. For some tasks, the needed registers will be
spread throughout the map, so this section helps the user locate the registers.
Section 5 -Register Mapscontains the complete register maps - The main register map contains cross-reference links to
sections within the document that contain the relevant details on using each bit described.
Use of Register Bits
Different bits on a single byte may have various functions. ▶ Section 4 -Programming Tasks may refer to an isolated bit.
Using a “read, modify, write” method when changing the value of these bits is recommended to guarantee that other bits in
the register will not be affected. To find the functions of other bits in the byte, refer to ▶ Section 5 -Register Maps, where the
Reference column points to the section with more detailed information about the register.
1.1.3
Register Types
Registers that do not have a defined functionality will be one of three types:
1.1.4
Fixed
Value may need to be set one time, but should never be changed.
Reserved
Register exists, but has no function.
Not Used
Register does not exist and will always be read back as 0. Any register not defined in the
complete register map fits this description.
Format Standards
In this document, ADI has chosen to represent data in the following ways:
0xNN
Hexadecimal (base-16) numbers are represented using the “C” language notation,
preceded by 0x.
0bNN
Binary (base-2) numbers are represented using “C” language notation, preceded by 0b.
NN
Decimal (base-10) numbers are represented using no additional prefixes or suffixes.
Bit
Bits are numbered in little-endian format; i.e., the least-significant bit of a byte or word is
referred to as bit 0.
Bit descriptions in the register maps are assumed to be binary.
1.1.5

I2C Bus
The ADV7511 uses four I2C register maps. The SDA/SCL programming address for the Main Register Map is 0x72 or 0x7A,
based on whether PD/AD is pulled high (10KΩ resistor to power supply = 0x7A) or pulled low (10KΩ resistor to GND =
0x72) when power is applied to the supplies. The user should wait 200ms for the address to be decided, after the power
supplies are high, before attempting to communicate with the ADV7511 using I2C. A complete listing of the Main Register
Map is provided in Section 5 -Register Maps Refer to the “I2C Interface (access to the ADV7511 registers)” section in the
▷ ADV7511 Hardware User’s Guide for information about I2C hardware.
The device address for the Packet Memory is programmable and is controlled by register 0x45 of the Main Register Map. The
default setting is 0x70. The details of the Packet Memory Map can be found in ▶ Table 112.
The EDID Memory address is programmable and controlled by register 0x43 of the Main Register Map.The default setting is
0x7E. The details of the CEC Memory Map can be found in ▶ Table 113.
The CEC Memory address is programmable and controlled by register 0xE1 of the Main Register Map. The default setting is
0x78. Unless otherwise stated, all register references in this document refer to the Main Register Map.
The Fixe I2C Address register 0xF9 needs to be set to an I2C address that does not conflict with any other address on the
board. 0x00 is an appropriate setting.

ADV7511
General Control
Hot Plug Detect (HPD) and Monitor Sense
To operate the ADV7511, it is necessary to monitor the Hot Plug Detect (HPD) signal and power up the part after HPD
becomes high. To power up the part, the Power Down register bit (0x41[6]) must be written to 0 when the HPD pin is high.
The status of the HPD pin can be read in register bit 0x42[6]. Both the HPD pin and Capability Discovery and Control (CDC)
HPD will be used for the internal HDCP signal. The CDC HPD signal is used as the HPD signal when HEC is active, because
the physical HPD line needs to be held high for HEC. The HPD source can be selected with the HPD Control Register Bits
0xD6[7:6]. When these bits are set to 0b00, both the HPD pin and CDC HPD will be used for the internal HPD signal. When
these bits are set to0b01 only the CDC HPD will be used, and 0b10 means that only the HPD pin will be used. When
0xD6[7:6] is set to 0b11 the HPD signal will always be high, but the HPD interrupt will still respond to the HPD pin. To use
the CDC HPD register bit 0x7F[6] of the CEC Map must be set to 1 and 0x80 and 0x81of the CEC Map need to be set to
products containing the HDMI Tx’s physical address.
When the signal on HPD is low, some registers cannot be written to. When HPD goes from high to low, some registers will be
reset to their defaults. For additional details see ▶ Table 97. Refer to ▶ 4.11 for details on the use of interrupts.
If there is a need to power up the part when the HPD signal is low, the HPD can be overridden using the HPD Control
register bit (0xD6[7] = 1. This would be needed, for example, when reading the EDID from an HDMI port when the HPD is
low in order to find its CEC physical address.
The best method to determine when the HPD is high is to use the interrupt system. The bit representing an HPD interrupt is
0x96[7]. Refer to ▶ 4.11 for details on the use of interrupts.
Monitor Sense refers to the detection of TMDS clock line pull-ups in the HDMI sink. If greater than 1.8V is detected, the
Monitor Sense interrupt will be triggered and the Monitor Sense State bit (0x42[5]) will be 1.
One reason to detect the Monitor Sense is to delay powering up the chip until the Rx is actually ready to receive signals. A
typical implementation for a sink is to tie the HDMI 5V to HPD through a series resistor. In this case, the HPD signal will be
detected regardless of whether the sink is powered on and ready to receive audio and video. For this reason it is best to wait
for both the Monitor Sense and HPD before powering up the chip when trying to achieve minimum power consumption.
An internal weak pull-down resistor is available in the HDMI Tx to reduce BOM cost. This can be enabled by setting the
HPD Pull Down register bit 0xE0[0] to 1.

HDMI DVI Selection
The HDMI Transmitter supports both HDMI and DVI modes. HDMI or DVI mode is selected by 0xAF[1]. In DVI mode no
packets will be sent, and all registers relating to packets and InfoFrames will be disregarded. DVI only supports the RGB color
space, so, if the input is not RGB, it is important to remember to set the color space conversion to output RGB when DVI is
enabled. See ▶ 0 for details about the Color Space Converter. The current mode of HDMI or DVI can be confirmed by the
read only (RO) bit 0xC6[4].

AV Mute
The AV Mute bits are sent to the Rx through the General Control Packet (GCP). One purpose of the AV Mute is to alert the
Rx of a change in the TMDS clock so the Rx can mute audio and video. AV Mute also pauses HDCP encryption, so the
HDCP link is maintained while the TMDS clock is not stable. It can also be used in general to tell the sink to mute audio and
video. AV Mute is not sufficient as a means to hide protected content, because the content is still sent even when AV Mute is
enabled.
To use AV Mute, enable the GCP by setting the GC Packet Enable register bit (0x40[7]) to 1. To set AV mute, clear the Clear
AV Mute bit (0x4B[7] = 0) and set the Set AV Mute bit (0x4B[6] = 1). To clear AV mute, clear Set AV Mute (0x4B[6] = 0) and
set Clear AV Mute (0x4B[7] = 1). Note that it is invalid to set both bits to 1.
To avoid a partial update of the General Control packet, the Packet Update features should be used. By setting the GC Packet
Update register bit (0x48[4] Packet Memory) to 1, the current values for GC Header and Packet Bytes will be stored and sent
in the GC Packets. The user should update the values then set the GC Packet Update register bit to 0 to begin sending the
new packets.

TMDS Power-Down
The differential outputs of the ADV7511 can be powered down. This can be useful for ensuring that no invalid data will be
put on the HDMI link until the register settings have been confirmed.
To avoid glitches in the TMDS clock at turn-on, a soft TMDS clock turn-on feature is provided. Enable the two Soft TMDS
Clock Turn On registers before disabling Clock Driver Power Down. When the clock is active, disable the Soft TMDS Clock
Turn On registers.
The TMDS Clock can be inverted by setting the TMDS Clock Inversion register bit 0xDE[3] to 1. This can be useful when
using test equipments that has a dependency on the relationship between the TMDS clock and data.

▶Figure 1 shows a block diagram depicting the internal structure of the Packet Update block of the ADV7511. As seen in
▶Figure 1, only one Packet Update Buffer is available, which means that only one Packet can be updated at a given time.
When the respective Packet Update register bit is set to ‘1’, the contents of the packet are copied over from I2C memory to the
Packet Update Buffer, and during this time the I2C contents can be updated without causing any disturbances on the screen.
Copying over from I2C memory contents to the Packet Update Buffer happens within one TMDS clock cycle. Once the
update is finished, the respective Packet Update register bit can set back to ‘0’, and the next packet can be updated. As seen in
the below figure, when the respective Packet Update register bit is set to ‘1’, the contents of the Packet Update Buffer are used
instead of the I2C memory contents to send across the TMDS link.It should be noted that at all packet updates are sent across
the TMDS link during the next available blanking period.

System Monitoring
The ADV7511 utilizes both interrupts and registers to report errors and the status of internal operations. See ▶ 4.11 for details
about using interrupts.
4.2.8.1
DDCController Status
The current state of the DDC controller can be read from the DDC Controller State I2C register (0xC8 [3:0]). The codes for
this register are shown in ▶ Table 11.

HDCP/EDID Controller Error Codes
If an error occurs, the ADV7511 can send and interrupt. See ▶ 4.11 for details about using interrupts. An error code is then
reported in the DDC Controller Error register (0xC8 [7:4]). ▶ Table 12 lists the possible error conditions and the
corresponding 4-bit error code. The error code is only valid when the error interrupt is 1. The last error code will remain in
the DDC Controller Error register even when the interrupt is cleared.

Fixed Registers That Must Be Set
After HPD becomes low the ADV7511 will be powered down and many registers reset. When HPD becomes high, it must be
powered up by using the Power Down register bit (0x41[6]). The following fixed registers should be set after power up:

Video Setup
Input Formatting
The ADV7511 accepts video data from as few as eight pins (either YCbCr 4:2:2 double data rate [DDR] or YCbCr 4:2:2 with
2x pixel clock) or as many as 36 pins (RGB 4:4:4 or YCbCr 4:4:4). In addition it accepts HSYNC, VSYNC and DE (Data
Enable). The ADV7511 is able to detect all of the 59 video formats defined in the ▷ EIA/CEA-861D specification. Either
Page 26 of 203
Rev G
PROGRAMMING GUIDE
ADV7511
separate HSYNC, VSYNC, and DE, or embedded syncs in the style of the ITU BT.656, SMPTE 274M, and SMPTE 296M
specifications are accepted. If less than 36 input pins are used, the alignment of the data can be defined as left justified (all
data begins from D35), right justified (all data ends at D0), or evenly distributed. In the case of evenly distributed, the channel
data is left-justified in their respective 12-bit fields. For example, an evenly distributed 24-bit RGB signal would have R[7:0]
mapped to D[35:28]; G[7:0] mapped to D[23:16]; and B[7:0] mapped to D[11:4].
▷
For timing details for video capture, refer to the Functional Description section of the ADV7511 Hardware User Guide.
The tables in ▶ 4.3.2 define how the many different formats are accepted on the input data lines.

Input Data Clock
When using an input format where the clock is 2 or 4 times the frequency of the data, such as 480i at 27MHz, CLK Divide
register bits (0x9D[3:2]) and the CLK Divide Reset Register bit (0xA4[6]) need to be set accordingly. ▶ Figure 5 illustrates this
function. The generated clock can be synchronized to the Hsync, Vsync, or DE. This can be selected in register bits 0xD0[3:2].
Register 0xBA controls the clock delay for the video data capture. For DDR, the negative edge clock delay can be controlled
independently of the positive edge. To enable independent, negative-edge DDR control, set 0xD0[7] to 1. The delay can be
controlled in register bits 0xD0[6:4].

Video Mode Detection
The video mode detection feature can inform the user of the CEA 861D defined Video Identification (VIC) of the video being
input to the ADV7511, as well as some additional formats. If an 861D format is detected, the VIC code is contained in register
0x3E[7:2]. Some additional non-861D formats are contained in 0x3F[7:5]. Some information from the user is required to
make the VIC determination for formats which can’t be distinguished by the automatic detection system. The aspect ratio
(0x17[1]) is used to distinguish between 861D video timing codes where aspect ratio is the only difference. The Low Refresh
Rate bits (0xFB[2:1]) inform the detection logic that a low-frequency Vsync format is being used, and specify the refresh rate.
These include 1080p with 24, 25, and 30Hz refresh rates. The High Refresh Rate bit (0xD5[3:2]) allows the detection circuit to
identify modes with 2x or 4x the normal refresh rate. For 240p and 288p modes the number of total lines can be selected in
0x3F[4:3]. The VIC detected is also affected by pixel repeat; see ▶4.3.4.
The detected VIC will be sent in the AVI InfoFrame unless pixel repetition is applied, causing the sent VIC to be different. To
override the VIC detection, the pixel repeat mode must be set to manual by setting register 0x3B[6:5] to 0b10 or 0b11. The
desired VIC is input into 0x3C[5:0]. The transmitter can support non-CEA 861D modes, but these will not be automatically
detected. In this case the VIC should be 0.

Pixel Repetition
Pixel repetition is used in HDMI to increase the amount of blanking period available to send packets or to increase the pixel
clock to meet the minimum specified clock frequency. The ADV7511 offers three choices for the user to implement this
function: auto mode, manual mode, and max mode (0x3B[6:5]). If using SPDIF or I2S the ADV7511 can automatically select
the necessary pixel repetition multiple for combinations of video format and audio sample rate. The video is converted to the
appropriate format within the ADV7511, and the resulting VIC is sent in the AVI InfoFrame. Note that automatic pixel
repeat does not work for HBR, DSD, and DST audio formats.
In automatic mode, the ADV7511 takes the audio sampling rate and detected VIC information as parameters to decide if
pixel repeat is needed to obtain sufficient blanking periods to send the audio. For I2S, the sampling rate is determined by
register 0x15. The audio sampling rate is either determined by the channel status information of the incoming SPDIF data, or
by setting register 0x15. In the case of SPDIF, the source of the sampling rate information is set in register 0x0C[7]. With I2S,
the sampling rate is always set by the user. If the pixel repetition factor is adjusted to meet bandwidth requirements, then the
detected input VIC may be different from the VIC sent to the Rx. The VIC of the actual video sent, which is included in the
AVI InfoFrame, can be seen in register 0x3D[5:0].
In the manual pixel repeat selection case, the VIC sent in the AVI info frame will need to be set in register 0x3C. The
multiplication of the input clock must be programmed in 0x3B[6:5], and the pixel repeat value sent to the Rx must be
programmed in 0x3B[4:3]. Refer to the ▷ HDMI 1.3 specification for more details on valid pixel repeat formats.
Max mode works in the same way as the automatic mode, except that it will always select the highest pixel repeat multiple the
HDMI Tx is capable of. This makes the video timing independent of the audio sampling rate. This mode is not typically used.

422 444 Conversion
The ADV7511 can up-convert from 4:2:2 format to 4:4:4 format as well as down-convert from 4:4:4 to 4:2:2. To convert from
4:4:4 to 4:2:2, the video data always goes through a filter first to remove any artificial down-sampling noise. To convert from
4:2:2 to 4:4:4, the ADV7511 utilizes either the zero-order up-conversion (repetition) or first-order up-conversion (linear

interpolation). The type of interpolation, zero or first order, can be selected in register 0x17[2], and interpolation will give the
best results.
The up-conversion and down-conversions are automatically applied when the video output format does not match the video
input format. The input format is selected as described in ▶ 4.3.1, and the output format is selected in bits 0x16[7:6].
4.3.6
Deep Color Conversion
Deep Color Output can be selected by the GC CD register bit (0x4C[3:0]). The GC CD sets the output depth as well as the CD
field in the general control packet. If the input video has less than the number of bits specified in GC CD, the extra LSBs will
be filled with 0. When the input video has more information than the output, color depth bit trimming is automatically used.
The method for color depth trimming can be selected using the Bit Trimming Mode register bits (0x49[7:2]). To enable Deep
Color the General Control Packet must be enabled by setting the GC Packet Enable register bit 0x40[7] to 1.
To avoid a partial update of the General Control packet, the Packet Update features should be used. By setting the GC Packet
Update register bit (0x48[4] Packet Memory) to 1, the current values for GC Header and Packet Bytes will be stored and sent
in the GC Packets. The user should update the values then set the GC Packet Update register bit to ‘0’ to begin sending the
new packets. See section 4.2.5 for details.

DE, Hsync and Vsync Generation
When transmitting video data across the TMDS interface, it is necessary to have an Hsync, Vsync, and Data Enable (DE)
defined for the image. There are three methods for sync input to the ADV7511. See ▶ Figure 6for a block diagram of the sync
processing capabilities. For 3D formats extended MSBs for several DE, Hsync and Vsync generation fields have been added in
registers 0xFA and 0xFB. For standard CEA861 formats, these registers can be left at default.
Separate Hsync, Vsync, and DE
For this method, all necessary signals are provided so neither Sync generation or DE generation is required. If desired, the
Page 52 of 203
Rev G
PROGRAMMING GUIDE
ADV7511
user can adjust the Hsync and Vsync timing relative to DE (refer to Hsync and Vsync adjustment section). Also, the DE
timing can be adjusted relative to Hsync and Vsync. If both Hsync and Vsync adjustment and DE adjustment are chosen, the
order can be selected. By setting register 0xD0[1] to 0, first the Hsync and Vsync is adjusted based on the input DE, then the
DE timing is adjusted based on the new Hsync and Vsync. By setting register 0xD0[1] to 1, first the DE timing is adjusted
based on the input Hsync and Vsync, then the Hsync and Vsync timing is adjusted based on the new DE.
Embedded Syncs (SAV and EAV)
This method requires that Hsync and Vsync be generated. Registers 0x30 through 0x34 and 0x17[6:5] contain the settings for
Hsync and Vsync generation in the embedded sync decoder section. The ADV7511 will use the signal generated by the EAV
and SAV as the DE by default, but a new DE can also be generated. Sync adjustment is also available. If both Hsync and
Vsync adjustment and DE adjustment are chosen, the orderin which they are implemented can be selected. By setting register
0xD0[1] to 0, first the Hsync and Vsync is adjusted based on the signal defined by the SAV and EAV, then the DE timing is
generated based on the new Hsync and Vsync. This is useful if the interlace offset feature is desired, because it is available in
the sync adjustment section, but not the embedded sync decoder section. By setting register 0xD0[1] to 1, first the DE timing
is adjusted based on the Hsync and Vsync generated by the embedded sync decoder, then the Hsync and Vsync timing is
adjusted based on the new DE.
Separate Hsync and Vsync only
This method requires that a DE be generated. Hsync and Vsync can also be adjusted based on the new DE if desired by
enabling the Hsync and Vsync generation and setting the order to DE generation then Hsync Vsync Generation. This would
be necessary if the location of the separate Hsync and Vsync were not in the same position relative to the data in the input
signal, as the Hsync and Vsync defined in the CEA 861 are to the DE defined in the CEA 861.

External Sync Input Modes
To properly frame the active video, the ADV7511 can use an external DE (via external pin) or can generate its own DE signal.
To activate the internal DE generation, set register 0x17[0] to 1. Registers 0x35 – 0x3A and 0xFB are used to define the DE.
Registers 0xFB[7],0x35 and 0x36[7:6] define the number of pixels from the Hsync leading edge to the DE leading edgeminus
one. Registers 0xFB[6:5] and 0x36[5:0] is the number of Hsyncs between leading edge of VS and DE. Register 0x37[7:5]
defines the difference of Hsync counts during Vsync blanking for the two fields in interlaced video. Registers 0xFB[4],
0x37[4:0] and 0x38[7:1] indicate the width of the DE. Registers 0x39 and 0x3A[7:4] are the number of lines of active video.
These adjustments are illustrated in ▶ Figure 7.
Embedded Sync Input Mode
The F, H, and V codes from the embedded syncs define the DE by default in the ADV7511. To achieve 861D formats at the
output by default, the embedded sync V signal needs to be aligned with the data as specified in the ▷ 861D specification.
The internal DE generator can also be enabled when using embedded syncs by setting register 0x17[0] to 1. The default
reference point for the DE parameters are the Hsync and Vsync from the embedded sync decoder block which are defined by
registers 0x30 – 0x34. The adjusted Hsync and Vsync output can also be used as the reference for DE generation if desired.

Hsync and Vsync Generation
For video with embedded syncs, it is necessary to reconstruct the Hsync and Vsync. This is done with registers 0xFA, 0x30 –
0x34 and 0x17[6:5]. Registers 0xFA[7:5],0x30 and 0x31[7:6] specify the number of pixels between the Hsync leading edge and
the trailing edge of DE. Registers 0x31[5:0] and 0x32[7:4] are the duration of the Hsync in pixel clocks. Registers 0x32[3:0] and
0x33[7:2] are the number of Hsync pulses between the trailing edge of the last DE and the leading edge of the Vsync pulse.
Registers 0x33[1:0] and 0x34[7:0] are the duration of Vsync in units of Hsyncs. Hsync and Vsync polarity can be specified by
setting registers 0x17[5] and 0x17[6]. ▶ Figure 8 –▶Figure 10 show the sync generation parameters.
4.3.7.3
Hsync and Vsync Adjustment
Hsync and Vsync can also be adjusted based on a DE input, output of the embedded sync decoder, or output of the DE
generator. Setting 0x41[1] to 1 enables this function. Registers 0xFA and 0xD8 – 0xDD set the Hsync and Vsync parameters.
Register 0x17[6:5], shared with the embedded sync decoder, is used to set the polarity. For interlaced formats the Vsync
placement is independent with each field. The Vsync Placement for interlaced fields is adjusted as shown in ▶ Figure 10,
where Vsync Placement is set in registers 0xD9[3:0] and 0xDA[7:2], and offset is set in register 0xDC[7:5].

DE, Hsync, and Vsync Generation Recommended Settings
The following 4 tables show recommended settings for DE and Sync generation and adjustment. The settings are dependent
on the video input, so these settings are intended to be used as a starting point. Some adjustments may be required from
these settings to achieve a CEA861 compatible output.

Color Space Converter (CSC)
The color space converter (CSC) is a flexible 3x3 matrix that is capable of converting between a wide variety of color spaces.
This section contains full details on the function of the CSC and register settings for common conversions.

Color Space Conversion (CSC) Matrix
The color space conversion (CSC) matrix in the ADV7511 is a 3 x 3 matrix with full programmability of all coefficients in the
matrix. Each coefficient is 13 bit 2s complement to ensure that signal integrity is maintained. The CSC is designed to run at
pixel rates of up to 170MHz. With the “any-to-any” color space conversion capability, formats such as RGB, YUV, YCbCr
and others are supported by the CSC.
The CSC contains three identical processing channels, one of these is shown in ▶ Figure 11. The main inputs, In_A, In_B, and
In_C, come from inputs to the ADV7511. Each input to the individual channels to the CSC is multiplied by a separate
coefficient. In ▶ Figure 11these coefficients are marked A1, A2, and A3. The variable labeled A4 in ▶ Figure 11 is used as an
offset control for Channel A in the CSC. The functional diagram for a single channel in the CSC, as per ▶ Figure 11, is
repeated for the other two remaining channels, B and C. The coefficients for these channels are called B1, B2, B3, B4, C1, C2,
C3 and C4.

As can be seen from Equations 1-3, the A1-A3, B1-B3, and C1- C3 coefficients are used to scale the primary inputs. The values
of A4, B4 and C4 are then added as offsets. The CSC Mode bits (register 0x18[6:5]) allow the user to implement conversion
formulas in which the conversion coefficients are ≥ 1. In other words, if an equation is being implemented whose coefficients
are ≥ 1, the CSC Mode bits can be used to ensure that the resulting output code does not exceed the 12-bit limit of 4095.
▶ Table 37 describes the conditions under which each CSC Mode setting should be used. Note that if any coefficient in any of
the three CSC equations requires scaling (CSC Mode ≠ 0), then all coefficients, including the offset values, are scaled as
indicated by Equations 1 - 3. The values of A1 - A4, B1 - B4, and C1 - C4 will equal the coefficients from the desired
conversion formula multiplied by 4096 .

Color Space Converter (CSC) Special Features
The Colorspace Converter also has three special features. For the case where YCbCr with a code range from -128 to 127 is
input, setting bit 0xD5[1] to 1 will shift the code ranges to 0 - 255. If the user requires a black image to be sent across the
HDMI link register 0xD5[0] should be set to 1, and register 0x16[0] should be set according to the output colorspace. The
black image can be useful for protecting copyrighted content during HDCP authentication.
The minimum and maximum values for Y and CbCr can be set using the register in ▶ Table 65. For RGB, only the Y value
will be used. YCbCr and RGB are distinguished by using the Input Color Space register bit (0x16[0]). This can be useful to
ensure that video codes do not stray outside of the specified range when using limited range RGB or YCbCr.
4.3.8.3
Changing the Color Space with Active Display
The Color Space Converter Enable register bit 0x18[7] can cause the video to become momentarily unstable. To avoid this,
time the end of the I2C write to coincide with the back porch of the Vsync. The Vsync interrupt can be used to synchronize
the I2C write.

Method 1:
When Coefficient Update is always 0, the coefficient will be updated directly.
Method 2:
When Coefficient Update is used, there are 3 steps for updating
a) Set Coefficient Update = 1 to buffer the CSC Coefficients
b) Set the new CSC Coefficients
c) Set Coefficient Updated = 0 to enable the new CSC Coefficients at the next Vsync

PROGRAMMING GUIDE
ADV7511
To avoid a partial update of the packets the Packet Update features should be used. By setting the Packet Update register bit
to 1 the current values will be stored and sent in the packets. The user should update the values then set the Packet Update
register bit to 0 to begin sending the new packets. See section 4.2.5 for details.
4.3.9.1
AVI InfoFrame
The AVI InfoFrame is sent to the receiver to help it determine the intended aspect ratio and other formatting parameters of
the video being transmitted across the HDMI link. The Y1Y0 bits (0x55[6:5]), which tell the sink whether YCbCr 4:2:2,4:4:4
or RGB are sent, and the Picture Aspect Ratio bits (0x56[5:4]) are required fields. Other field data can be entered if the
information is available.
The Active Format Information Status bit (0x55[4]) tells whether the Bar Information, Scan Information, Colorimetry, Nonuniform Picture Scaling, and Active Aspect Ratio fields contain valid information.
The Active Format Aspect Ratio bits (0x56[3:0]) give the receiver useful information about the video that can be used to
improve the picture. The Active Format Description code from the ETSI TR 101 151 version 1.4.1 Digital Video Broadcasting
Specification, which is mentioned in ▷ CEA 861D, should be entered into this field. Additional formats can be entered
manually in the bar information fields.
Registers 0x5A – 0x61 tell the receiver if there are black bars included in the video stream. Register 0x55[3:2] tells the receiver
which bar information is valid: none, horizontal, vertical, or both.
To make sure theAVI InfoFrame information isn’t partially sent while being updated the packet update feature can be used.
The AVI Packet Update register bit (0x48[6]), should be set to 1, then the AVI Packet Registers written, and finally set back to
0. See section 4.2.5 for details.

Gamut Metadata Packet
The Gamut Metadata Packet (GMP) contains the sources Gamut Boundary Description. It is defined in the ▷ HDMI 1.3a
specification.
The contents of the GMP InfoFrame are set in the Packet Memory. The device address for the Packet Memory map is
programmable and is controlled by register 0x45 of the primary register map. The default setting is 0x70. Transmission of the
GMP data over the HDMI link is enabled by setting the GMP Enable bit (0x40[2] of the Main Register Map) to 1.
The ADV7511 transmits the GMP data starting 400 pixel clock cycles after the leading edge of Vsync. In order to update the
GMP at the expected frame, it is recommended that the user set the packet update bit to 0 after the 512th pixel clock cycle
after the Vsync leading edge. The Vsync interrupt of the ADV7511 should be used to synchronize this timing. ▶ Figure
12illustrates this GM Packet timing.

3D Video Setup
When sending 3D video formats from the ADV7511, both the VIC in the AVI InfoFrame and the Vendor Specific InfoFrame
must be setup.
4.3.10.1 VIC
The ADV7511 does not detect the VIC for 3D formats. The VIC must be programmed using the manual pixel repeat mode
by setting 0x3B[6:5] to ‘10’. The VIC should be programmed in register bits 0x3C[5:0]. A list of VICs can be found in the
CEA861 document.
4.3.10.2 Pixel Repeat
The Pixel repeat value should be set in register 0x3B[2:1] and 0x3B[4:3]. This will be 0 for most formats However, depending
on the audio and video formats used, sometimes pixel repeat must be used to increase the bandwidth available for
audio. Look at table 7-5 in HDMISpecification1.4 to determine the appropriate pixel repeat value for the 2D VIC and audio
format, then look at ▶ Table 72 to select the an appropriate PR for the corresponding 3D structure.

4.4.1.1
Inter-IC Sound (I2S) Audio
The ADV7511 can accommodate from two to eight channels of Inter-IC Sound (I2S) audio at up to a 192KHz sampling rate.
The number of channels can be selected in register 0x73[2:0] Which I2S channels are active can be selected in register
0x0C[5:2] If all eight channels (I2S0 – I2S3) are required, setting all bits in registers 0x73[2:0] and 0x0C[5:2] to 1 will select
eight channels. If I2S0 only is needed, setting the Channel Count register (0x73[2:0]) and I2S enable (0x0C[2]) to 1 will select
this. The I2S Sampling Frequency (0x15[7:4]) must be set appropriately. This value is used along with the VIC to determine
pixel repeat (see ▶ 4.3.4) and sent across the TMDS link in the channel status information contained in the Audio Sample
Packet.
The placement of I2S channels into the Audio Sample Packet Subpackets, defined in the ▷ HDMI specification, can be
specified in registers 0x0E – 0x11. Default settings place all channels in their respective position (I2S0 left channel in channel
0 left position, I2S3 right channel in channel 3 right position), but this mapping is completely programmable if desired.
The ADV7511 supports standard I2S, left-justified, right-justified, and direct AES3 stream formats via register 0x0C[1:0] and
sample word lengths between 16 bits and 24 bits (0x14[3:0]). The ADV7511 supports both 64-bit and 32-bit modes, so either
64 or 32 SCLK edges per channel are valid. The ADV7511 will adapt to 32 or 64 bit mode automatically, and the current
mode can be read in register 0x42[3]. See ▶ Figure 15– ▶ Figure 20 for I2S format details.
In the direct AES3 stream I2S format, the user can send an IEC60958 sub-frame, seen in ▶ Figure 13. The data should be
aligned as seen in ▶ Figure 18, with the Preamble left out as shown in ▶ Figure 14. Notice that the parity bit is replaced by the
block start flag. The parity bit will be calculated automatically. The information contained in "C" of I2S0 is used in the HDMI
audio sample packet. This information can either be extracted from the stream or programmed through the ADV7511
register map. To choose the channel status source, use register 0x0C[6]. When Channel Status Override (0x0C[6]) is set to
extract channel status information from the register map, by setting Audio Sampling Frequency Select (0x0C[7]) to 1, all of
the data from the stream will be used except the sampling frequency will be obtained through the Sampling Frequency
register (0x15[7:4]). When Audio Sampling Frequency Select is set to 1, the sampling frequency from the register map will be
used for pixel repetition decisions as well.

Sony/Philips Digital Interface (SPDIF) Audio
The ADV7511 is capable of accepting two-channel LPCM and encoded multi-channel audio up to a 192KHz sampling rate
via the Sony/Philips Digital Interface (SPDIF). The detected sampling frequency for SPDIF (from 32KHz to 192KHz) can be
read in register0x04[7:4]. For SPDIF, by setting the Audio Frequency Select register (0x0C[7]) to 1, the sampling frequency
used to determine pixel repeat can be obtained by the Sampling Frequency register (0x15[7:4]) instead of extracted from the
stream; however the sampling frequency read in the SPDIF Sampling Frequency register (0x04) will be sent in the audio
sample packet channel status. The ADV7511 is capable of accepting SPDIF with or without an MCLK input. When no MCLK
is present, the ADV7511 uses MCLK to internally generate the MCLK and determine the CTS value.

Direct Stream Digital (DSD) Audio
Direct Stream Digital (DSD) Audio uses the One Bit Audio packets to transfer data across the TMDS link. Up to eight
channels of DSD data can be input onto eight data lines clocked by the DSD_CLK. DSD can be selected as the input format
using the Audio Select register (0x0A[6:4]) = 0b010. Raw mode or SDIF-3 mode can be selected by the Audio Mode register
(0x0A[3]). Each input can be enabled or disabled in the DSD Enable register (0x46). ▶ Table 73 shows the register settings for
different modes.
For DSD, the Sampling Frequency (Audio InfoFrame) register (0x74[4:2]) needs to be set.Manual pixel repeat mode should
be used for DSD as described in Section▶ 4.3.4.The DSD clock and data are 64 times the corresponding PCM sampling
frequencies.

High Bit-Rate (HBR) Audio
High Bit-Rate (HBR) audio uses the HBR audio packets to transfer compressed data at rates greater than 6.144Mbps across
the TMDS link. HBR Audio can be selected as the input format using the Audio Select register (0x0A[6:4]) = 0b011. The use
of four-stream or one-stream encoding can be set in the Audio Mode register (0x0A[3]), and the BPM encoding can be
selected or deselected using the Audio mode register (0x0A[2]). ▶ Table 73 shows the register settings for different modes.
Register 0x47[6] can be toggled from 0 to 1 to synchronize the PaPb syncword, which marks the beginning of a stream
repetition, with HDMI HBR subpacket 0. For data bursts with a repetition period, which is a multiple of four frames, the
synchronization will persist. If the data burst does not have a repetition period of four frames, setting register 0x47[6] to 1 is
not needed, but will not have any negative effects. The transition of the bit from 0 to 1 causes the one-time synchronization,
so setting the bit from 1 to 0 will have no effect.
For HBR Audio, the Sampling Frequency register (0x15[7:4]) needs to be set to 0b1001.Manual pixel repeat mode should be
used for DSD as described in Section▶ 4.3.4. An MCLK is always required for the BPM encoding modes.

The mapping from the I2S input channels to the HBR subpackets can be set by registers 0x0E to 0x11. When using an ADI
HDMI Rx as the input the default should be used. Since there is no standard for chip to chip HBR transfer, different settings
may be required for different chips used as the input.

N and CTS
Audio data carried across the HDMI link, which is driven by a TMDS (video) clock only, does not retain the original audio
sample clock. The task of recreating this clock at the Sink is called Audio Clock Regeneration. There are varieties of clock
regeneration methods that can be implemented in an HDMI Sink, each with a different set of performance characteristics.
The ▷ HDMI specification does not attempt to define exactly how these mechanisms operate. It does, however, present a
possible configuration and define the data items that the HDMI Source shall supply to the HDMI Sink in order to allow the
HDMI Sink to adequately regenerate the audio clock. It also defines how that data shall be generated. In many video source
devices, the audio and video clocks are generated from a common clock (coherent clocks). In this situation, there exists a
rational (integer divided by integer) relationship between these two clocks. The HDMI clock regeneration architecture can
take advantage of this rational relationship and can also work in an environment where there is no such relationship between
these two clocks; that is, where the two clocks are truly asynchronous or where their relationship is unknown.

Figure 22
The Audio Clock Regeneration model in ▶ Figure 22 illustrates the overall system architecture model used by HDMI for
audio clock regeneration. The Source shall determine the fractional relationship between the video clock and an audio
reference clock (128*audio sample rate) and shall pass the numerator and denominator for that fraction to the Sink across the
HDMI link. The Sink may then recreate the audio clock from the TMDS clock by using a clock divider and a clock multiplier.
The exact relationship between the two clocks will be:
128 f s = f TMDS _ CLK
N
CTS
The Source shall determine the value of the numerator N as specified in Section 7.2.1 of the ▷ HDMI specification. Typically,
this value N will be used in a clock divider to generate an intermediate clock that is slower than the 128*fS clock by the factor
N. The Source will typically determine the value of the denominator Cycle Time Stamp (CTS) by counting the number of
TMDS clocks in each of the 128*fS/N clocks.
4.4.2.1
N Parameter
N shall be an integer number and shall meet the following restriction: 128*fS/1500Hz ≤N ≤128*fS/300Hz with a recommended
optimal value of 128*fS/1000Hz approximately equals N for coherent audio and video clock Sources. ▶ Table 80 – Table 82
can be used to determine the value of N. For non-coherent sources or sources where coherency is not known, the equations
above should be used.

CTS Parameter
CTS shall be an integer number that satisfies the following:

4.4.2.3
f TMDS _ CLK N
128 f s
Recommended N and Expected CTS Values
The recommended value of N for several standard pixel clocks are given in ▶ Table 80 – Table 82. It is recommended that
Sources with non-coherent clocks use the values listed for a pixel clock of “Other.”
The ADV7511 has two modes for CTS generation: manual mode and automatic mode. In manual mode, the user can
program the CTS number directly into the chip (0x07–0x09) and select this external mode by setting 0x0A[7] to 1. In
automatic mode, the chip computes the CTS based on the actual audio and video rates. This can be selected by setting 0x0A[7]
to 0 and the results can be read from 0x04 – 0x06. The manual mode is good for coherent audio and video, where the audio
and video clock are generated from the same crystal; thus CTS should be a fixed number. The auto mode is good for
incoherent audio -video, where there is no simple integer ratio between the audio and video clock. The 20 bit N value can be
programmed into the ADV7511 in registers 0x01–0x03.

Audio Sample Packets
By setting the Chanel Count (CC) register (0x73[2:0]) to greater than three channels, the eight-channel audio packet format
will be used. The I2S can be routed to different subpackets using registers 0xE – 0x11. The Channel Allocation (CA) register
(0x76[7:0]) must be set to a speaker mapping that corresponds to the I2S to subpacket routing. Using SPDIF has a default
setting of two channels.
The audio packets in HDMI use the channel status format from IEC60958. When using I2S, the information sent in the
channel status fields is provided by registers Copyright Bit (0x12[5]), Pre-emphasis (0x12[4:2]), clock accuracy (0x12[1:0]),

In ▶ Figure 23 the layout bit in the Audio Sample Packet Header and the sample_present.spX bit are determined based on the
Audio InfoFrame Channel Count register (0x73[2:0]). For example, if Channel Count = 0b001, indicating stereo audio, the
layout bit will be zero and all Audio Sample Subpackets will contain information for channel 1 and 2. If Channel Count =
0b011, indicating four channels, the layout bit will be one, and sample_present.sp0 = 1, sample_present.sp1 = 1,
sample_present.sp2 = 0, and sample_present.sp2 = 0. ▶ Figure 23 shows how the channel number bits will be set based on
the layout bit and sample_present.spX.

Audio InfoFrame
The audio InfoFrame allows the receiver to identify the characteristics of an audio stream before the channel status
information is available. The Audio Channel Count register (0x73[2:0]) sets the channel count field for the InfoFrame, and
determines the number of channels to send in the audio sample packets. Down Mix Inhibit (0x77[7]), Level Shift Values
(0x77[6:3]), and Speaker Mapping (0x76) are defined in the ▷ CEA-861D specification. The number of channels in the
Channel Count register must match the number of channels in the Speaker Mapping register. The values for the Speaker
Mapping bits are included in ▶ Table 86 for reference.
To avoid a partial update of the Audio InfoFrame Packets the Packet Update feature should be used. By setting the Audio
InfoFrame Packet Update register bit to ‘1’, the current values will be stored and sent in the packets. The user should update
the values then set the Audio InfoFrame Packet Update register bit to 0 to begin sending the new packets. See section 4.2.5 for
details.

International Standard Recording Code (ISRC) Packet
If the Supports_AI bit in the Vendor Specific Data Block (VSDB) of the sink EDID is 1 then the International Standard
Recording Code (ISRC) packets 1 and 2 can be transmitted. The use of the ISRC fields is described in ▷ "DVD Specifications
for Read-Only Disc”, Part 4: AUDIO SPECIFICATIONS Version 1.0, March 1999, Annex B.
To avoid a partial update of the ISRC Packets the Packet Update features should be used. By setting the ISRC1 Packet Update
or ISRC2 Packet Update register bit to 1 the current values will be stored and sent in the packets. The user should update the
values then set the ISRC1 Packet Update or ISRC2 Packet Update register bit to 0 to begin sending the new packets. See

ADV7511
Audio Return Channel (ARC)
One of the HDMI v1.4 features that has been incorporated in the ADV7511 is the Audio Return Channel portion of HEAC .
With this capability, the TV can send back audio to the TMDS source for processing and distribution. This audio channel can
be sent over a differential pair (common mode component) or on a single line. The common mode signals are on the HEAC+
pin and the HEAC- pin. A single mode transmission will be on the HEAC+ pin. The ARC allows audio from a display with a
tuner to be sent to a receiver over the HDMI cable for better audio reproduction. All HDMI cables will support this feature
and use of this can reduce the amount of cables in the system.
The audio data is a stereo L-PCM (IEC 60958-1) stream supporting 32KHz, 44.1KHz or 48KHz sampling rates. These
represent a clock rate of respectively: 4.096MHz, 5.6448MHz and 6.144MHz. Compressed audio as described in IEC 61937 is
optional.
Control of the ARC is initiated by the sink over the CEC lines. The capabilities of the source can be discovered in this fashion
whenthe TMDS sink initiates the use of the ARC line(s).
4.5.1
ARC Configuration
The ADV7511’s ARC receiver accepts single-ended or common mode signals and directs the resulting SPDIF signal to the
SPDIF_OUT pin. A block diagram of the ADV7511’s ARC circuit is illustrated in ▶Figure 24.To initialize and power on the
ARC circuit, the following register bits must be set:
■ Select Single ended or common mode by setting 0xDF[7] to ‘0’ or ‘1’
■ Set “ARC Disable bit 0xDF[0] to ‘0’
When ARC is not being used, the ARC Disable bit (0xDF[0]) should be set to its default value of ‘1’. The ARC receiver
control registers are shown in ▶Table 92.

EDID Handling
The ADV7511 has an I2C master (DDCSDA and DDCSCL) to read the EDID. It begins buffering segment 0 of the Sink’s
EDID after HPD is detected and ADV7511 is powered up. The system can request additional segments by programming the
EDID Segment register (0xC4). An interrupt bit 0x96[2] indicates that a 256-byte EDID read has been completed, and the
information is available in the EDID Memory. The EDID Memory is at I2C address 0x7E by default. This is the default
address but can be changed by writing the desired address into the EDID Memory Address register (0x43 of the main register
map).
4.6.1.1
EDID Definitions
EnhancedEDID (E-EDID) supports up to 256 segments. A segment is a 256-byte segment of EDID containing information
for either one or two 128-byte EDID blocks. A typical HDMI system will have only two EDID blocks and will only use
segment 0. The first EDID block is always a base EDID structure defined in VESA EDID specifications; the second EDID
block is usually the CEA extension defined in the ▷ CEA-861D specification.
EDID and HDCP use a shared memory space. During HDCP repeater initialization, the EDID data is overwritten with HDCP
information. EDID is not re-read after HDCP initialization. If the user would like to re-buffer an EDID segment the EDID
re-read register described in section 4.6.1.4 should be used.
4.6.1.2
Additional Segments
EDID block 0 byte number 0x7E tells how many additional EDID blocks are available. If byte 0x7E is greater than 1,
additional EDID segments will need to be read. If there is more than one segment, the second block (block 1) is required to be
an EDID extension map. This map should be parsed according to the ▷ VESA EDID specifications to determine where
additional EDID blocks are stored in the receiver’s EDID EEPROM.
The ADV7511 is capable of accessing any of the up to 256 segments allowed by the ▷ EDID specification. By writing the
desired segment number to register 0xC4, the ADV7511 will automatically access the correct portion of the EDID EEPROM
over the DDC lines and load the 256 bytes into the EDID memory. When the action is complete, an EDID ready interrupt
will occur to tell the user. If the host controller needs access to previously requested EDID information, then it can be stored
in its own memory.
▶ Figure 25 shows how to implement software to read EDID from the receiver using the ADV7511.

4.6.1.3
ADV7511
Reading EDID through the ADV7511
EDID Tries Register (0xC9 [3:0])
The EDID Tries register limits the number of times the HDCP/EDID controller will try to read the EDID. Each time an EDID
read fails with an I2C “Not Acknowledged” (NACK), this value is decremented. The default start-up value of this register is 3.
Once the EDID Tries register is 0, the controller will not attempt to read the EDID until this register is set to something other
than 0. This could be used if a sink asserts HPD before the DDC bus is ready resulting in several NACKs as the Tx attempts
to read the EDID.
4.6.1.4
EDID Reread Register (0xC9[4])
If the EDID data is read in and the host determines that the data needs to be reread, this bit can be set from 0 to 1 for 10 times
consecutively, and the current segment will be reread each time. This register should be toggled from 0 to 1 for 10 times
consecutively to ensure a successful capture of the register value. This could be useful if the EDID checksum is calculated and
determined not to match.
Another method to reread the EDID is to toggle the Main Power Down register bit (0x41[6]) from 0 to 1.

HDCP Handling
For One Sink and No Upstream Devices
The ADV7511 has a built-in micro-controller to handle HDCP transmitter states, including handling down-stream HDCP
repeaters. To activate HDCP from a system level the main controller needs to set the HDCP Desired register (0xAF[7]) to 1
and the Frame Encryption register (0xAF[4]) to 1, This informs the ADV7511 that the video stream should be encrypted. The
ADV7511 takes control from there, and implements all of the remaining tasks defined by the HDCP 1.3 specification. Before
sending audio and video, the BKSVs stored in registers 0xBF – 0xC3 should be compared with the revocation list which is
compiled by managing System Renewability Messages (SRMs) provided on the source content (typically a DVD), and the
BKSV Ready Interrupt register should be cleared. After the link is established, the system controller should monitor the status
of HDCP by reading the HDCP Encrypted register (0xB8[6]) every two seconds. The DDC Controller Error Interrupt register
(0x97[7]) will become active if there is an error relating to the controller. The meaning of the error can be determined by
checking the DDC Controller Error register (0xC8[7:4]).
4.7.2
For Multiple Sinks and No Upstream Devices
When connecting the ADV7511 to a repeater, it is necessary to read all BKSV from downstream devices. These BKSVs must
be checked against a revocation list, which will be provided on the source content.
The BKSV Count register (0xC7[6:0]) will read 0 when the first BKSV interrupt occurs. After the first BKSV interrupt is
cleared, if the device is a repeater, a second BKSV interrupt will occur. The ADV7511 will automatically read up to 13 5-byte
BKSVs at a time and store these in the EDID memory location (default location I2C address 0x7E). Refer to ▶ Table 94 for
details about the location of the downstream BKSVs. The number of additional BKSVs currently stored in the EDID memory
location can be read in register 0xC7[6:0]. If there are more than 13 additional BKSVs to be processed, the ADV7511 will
collect the next up to 13 BKSVs across the DDC lines, then generate another interrupt when the next set is ready. There can
be a maximum of 127 BKSVs total.
The BKVS Flag Interrupt register (0x97[6]) should be cleared by writing a 1 after each set of BKSVs is read. To check when
authentication is complete, the system should monitor the register DDC Controller State register (0xC8[3:0]) and wait until
this reaches state 4. At this time, the last step is to compare the BKSV list with the revocation list and then send the content.

For Use in a Repeater
The ADV7511 can be used in a repeater, which is a device that has one or more HDMI Rx upstream from the ADV7511. To
use the ADV7511 as a repeater, there are some additional requirements. The system software needs to pass the BKSVs of all
downstream devices upstream through the repeater’s receiver. In addition, the depth of the device tree and the total number
of devices need to be communicated upstream. This depth and device count information can be found in the BSTATUS
information, which is supplied in the EDID memory (default location I2C address 0x7E) at an offset of 0xF9 for the LSB's and
0xFA for the MSB’s. ▶ Table 94 shows the meaning of the bits in the BSTATUS bit field.
The BSTATUS information is only available when the BKSVs are in the memory space. This is from the time there is a BKSV
ready interrupt with BKSV Count register (0xC7[6:0]) greater than 0 to the time the interrupt flag is cleared. The EDID will
not automatically be re-buffered. If the user would like to re-buffer an EDID segment the EDID re-read register described in
section 4.6.1.4 should be used.
4.7.4
Software Implementation
▶ Figure 26 is a block diagram of HDCP software implementation for all cases using the ADV7511DDC Controller state
machine. The necessary interactions with the ADV7511 registers and EDID memory as well as when these interactions
should take place are covered in the block diagram. Note that there is no need to interact with the DDC bus directly, because
all of the DDC functionality is controlled by the DDC Controller and follows the ▷ HDCP specification 1.3.

ADV7511
AV Mute
AV Mute can be enabled once HDCP authentication is completed. This can be used to maintain HDCP synchronization
while changing video resolutions. While the BKSVs for downstream devices are being collected, an active HDCP link capable
of sending encrypted video is established, but video should not be sent across the link until the BKSVs have been compared
with the revocation list. It is not recommended to rely on AV mute to avoid sending audio and video during HDCP
authentication. This is because AV Mute does not actually mute audio or video in the Tx. It requests the function from the
Sink device. The best way to avoid sending unauthorized audio and video is to not send data to the ADV7511 inputs until
authentication is complete. Another option is to use the color space converter to black out the video and disable the audio
inputs to mute the audio. See ▶ 4.3.8.2 for how to black out the video, and see ▶ 4.3.10 for how to disable the various audio
inputs.
4.7.6
HDCP Delay Control
During the HDCP authentication there are several steps. The default timing for these steps is sufficient to meet all HDCP
requirements. However, in the case of unforeseen interoperability problems, control of the timing of several events is
available. The Ri Checking Frequency can be controlled by setting 0xFC[7:6]. The range of available setting is in powers of 2
between once every 128 frames as default (0b00), to once every 16 frames (0b11). Ri Checking occurs soon after the leading
edge of Vsync by default. Extra delay in units of Hsyncs can be added by setting the Ri Checking Position Delay register bits
0xFC[5:3]. After bit 0xAF[7] is set to 1 or an DDC Controller error interrupt occurs, usually the BKSV will be read
immediately. Delay can be added before this read by setting register 0xFE[7:5]. After the BKSVS are read, the BCAPS is read
immediately by default. Delay can be added here by setting register 0xFC[2:0]. After BCAPS is read the An value is written
immediately by default. Delay can be added here by setting register 0xFD[7:5]. After the An write is completed, the AKSV is
written immediately by default. Delay can be added here by setting 0xFD[4:2]. The time after AKSV is written before R0 is
read and the repeater timeout can be adjusted by register 0xD6[2:1].

Power Management
The ADV7511 has a Main Power Down, as well as additional methods, which can be used to further achieve power savings.
The Main Power-Down section describes the method and results of using Main Power Down. The Additional Power-Down
Methods section describes the methods and trade-offs for achieving minimum power consumption.
4.8.1
Main Power-Down
The ADV7511 can put into the Main Power-Down mode by the power-down pin or by register 0x41[6]. The ADV7511 will
power down if either the pin or register are active, but will only power up if both are inactive. Also the ADV7511 can only be
powered up if the HPD pin is 1. The conditions for Main Power Down are shown in Table 96.
The ADV7511 power-down pin polarity depends on the chip I2C address selection. If the user wants to use 0x72, then the
PD/AD pin is active high. If the user wants to use 0x7A, the PD/AD pin is active low. The power-down pin polarity can be
verified by reading register 0x42[7]. See the ADV7511 Hardware User’s Guide for more information about the PD/AD pin
and power specifications.
Some registers will be reset when the device is put into the Main Power-Down mode. Which registers are reset and which
registers retain their values depends on the method of power down used. The details are in ▶ Table 97.

Additional Power Down Methods
An ultra-low power down level can be achieved by setting the Monitor Sense Power Down register (0xA1[6]) to 1. As a
tradeoff interrupt handling and Monitor Sense monitoring cannot be used. With Monitor Sense Power-Down active, the
HPD State register (0x42[6]) is still valid. Polling of this register can be used to determine if a Sink is connected.
If SPDIF is not being used, the SPDIF Enable register (0x0B[7]) can be set to 0. This will turn off the SPDIF receiver. This is
not necessary during main power-down mode as the SPIDF receiver will be already powered down. CEC can be powered on
and off independent from the Main Power Down mode. If CEC is not being used, then the CEC Power Down bit (0xE2[0]),
can be set to 1.
If the inputs to the ADV7511 are toggling while the HDMI Tx is in power down mode, some power will be consumed. If
there is no way to disable the toggling of the data and clock input video, then clock gating can be used to reduce power. This
is activated by setting the Video Input and Clock Gating register (0xD6[0]) to 1. Similarly the CEC clock toggling will
consume some power. Disabling or reducing the speed of this clock will further save power during power down mode.

Consumer Electronic Control (CEC) is a single-wire, bidirectional interface intended to facilitate the control of any device on
an HDMI network, as shownin ▶Figure 27, with the remote control unit or on-device control buttons of any other device
connected to the network. Defined as an optional feature in the HDMI specification, it is based on the AV Link function
defined in the European SCART (Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) specification.
▶Table 100describes some typical end-user CEC features.

PROGRAMMING GUIDE
Figure 27
ADV7511
Typical All-HDMI Home Theatre
Table 100 Some typical“End-User” CEC Features:
Feature
One-Touch Play
Stand-By
One-Touch Record
Description
Pushing the “play” button commands a source to play and become the
active video source for the TV.
Pushing the “power down” button of any active device commands all
devices on the HDMI network to shut down.
Pushing the “record” button commands a recording device to power up
and record the content currently displayed on the TV.
Many of these end-user features require sending multiple messages over the CEC bus such as “Active Source,” and “Routing
Change,” which support the CEC feature “Routing Control.” This feature allows a device to play and become the active source
by switching the TV’s source input. If the TV is displaying another source at the time this command is used, it may place the
other source into “stand-by” mode, depending on the implementation. Please see the CEC section of the HDMI 1.4
specification for details about CEC itself.
4.9.1
CEC Addressing
On receiving the HPD Interrupt, the system software has to parse the EDID from the sink to determine the CEC device’s
Physical Address. Once this is done, the Logical Address is determined using a polling method as defined in the HDMI
Specification. Once the Logical Address is determined, it is programmed in to the Logical Address (0x4C[7:4]) register. The
ADV7511 allows the system to configure three separate Logical Addresses which can then be selected using the Logical
Address Mask (0x4B[6:4]) register. This allows the system to emulate up to three separate CEC devices using the same CEC
module.
4.9.2
CEC Transmitter
The CEC Transmitter module is used to describe the CEC messages when the on-chip CEC device acts as an initiator. The
host utilizes this module to transmit directly addressed messages or broadcast messages on the CEC bus.
Page 120 of 203
Rev G
PROGRAMMING GUIDE
4.9.2.1
ADV7511
CEC Transmitter Setup and Control
If the host wants to send a message to other CEC devices, the host should write the message to the CEC Tx Frame Data[0:14]
registers (0x01 -0x0F) and other CEC Tx-related control registers one by one. Finally, it will enable the transmission process
through setting the register bit of CECTx Transmission Enable (0x11[0]) to ‘1’. Then the CEC Tx module will kick off the
transmission process.
4.9.2.2
CEC Transmitter Interrupt Handling
When the message transmission is completed or any error occurs, the CEC Tx module will flag an interrupt signal to the host.
There are three kinds of interrupt sources in this module. These are Tx Ready, Tx Arbitration Lost, and Tx Retry Timeout. The
Tx Ready interrupt means that the message in the Tx buffer has been transmitted successfully and the CEC Tx module has
been ready to accept and transmit the next message. The Tx Arbitration Lost interrupt means that arbitration has been lost to
another initiator, when one or more other initiators are trying to access the bus at the same time as the ADV7511. The CEC
Tx module will stop transmitting and become a follower. The Tx Retry Timeout interrupt means that the initiator has tried to
transmit the message and retried up to the number of times, which is indicated by the Tx Retry register, with no acknowledge.
The reason for the failure is either due to a “no acknowledge” flagged by the follower, or low drive occurring on CEC bus. The
Tx Nack Counter shows how many times the transmission has failed because of a “no acknowledge.” The Tx Lowdrive Counter
shows how many times the transmission has failed because of low drive.
For these three interrupt types, only one can occur at a time, and the CEC Tx module will stop the transmission process
immediately. According to the interrupt type, the host must decide how to process the interrupt. ▶ Figure 28is the state
machine for control of the CEC message transmission process.

4.9.3
ADV7511
CEC Receiver
The CEC Rx module is used to retrieve CEC messages from the CEC bus when the on-chip CEC device acts as a follower.
The host utilizes this module to receive both broadcast messages and messages directly addressed to the ADV7511. The onchip CEC Rx module is equipped with three internal 16-byte frame buffers which can be used to improve system latency for
CEC message processing and reduce the likelihood of dropping messages.
4.9.3.1
CEC Receiver Setup and Control
The CEC Receiver module is enabled by setting 0x4E[1:0] = 0b01 if the CEC clock is enabled and timing parameters match
the clock frequency. The CEC Rx module will then monitor the CEC bus and accept the broadcast messages or messages
addressed directly to the device with the HDMI Tx.
To enable usage of all three internal frame buffers, the Use all CEC Rx Buffers (0x4A[3]) bit must be set. To provide
information on the order of arrival of a new frame in each buffer, three two-bit timestamp registers are available (0x26[5:0]).
Each timestamp register can contain a value between and including 0b01 and 0b11, depending on when a new frame arrives
at the corresponding CEC Rx Buffer. The earliest frame arrival is assigned a value of 0b01, and the latest frame arrival is
assigned a value of 0b11. A value of 0b00 for the timestamp indicates that no frame is currently present in the respective CEC
Rx Buffer. See Section ▶ 4.9.3.2.for more details on timestamp operation and processing.
Registers 0x77 – 0x7E are used to set pre-defined Wake Up Opcodes for the CEC Rx module. When an opcode which is
defined in these registers is received, a corresponding interrupt (0x93[7:0] in the Main Register Map) is generated. This
feature is not required for full featured CEC operation.
4.9.3.2
CEC Receiver Message Processing and Interrupt Handling
When any message besides a polling message is completely buffered in one of the CEC Rx Buffers, the CEC Receiver module
will set the corresponding CEC Rx Buffer Ready bit (0x49[2:0]), and also assert the corresponding CEC Rx Buffer Ready
Interrupt bit (0x97[2:0] Main Register Map).
Received CEC messages can be accessed from the CEC Rx Frame Buffer registers:
Buffer 1 – CEC Rx Buffer Frame Header + Data (0x15 – 0x24)
Buffer 2 – CEC Rx Buffer Frame Header + Data (0x27- 0x36)
Buffer 3 – CEC Rx Buffer Frame Header + Data (0x38 – 0x47)
Once the host processes the recently arrived frame (or earlier frame arrivals), the host system must clear the CEC Rx Buffer
Ready bit (0x49[2:0]) by toggling the value of the corresponding CEC Rx Buffer Ready Clear (0x4A[2:0]) bit. Toggling the
CEC Rx Buffer Ready Clear bit (0x4A[2:0]) resets the value of the respective timestamp to ‘0’. For example, when the CEC Rx
Buffer 3 Ready Clear (0x4A[2]) bit is toggled, the CEC Rx Buffer 3 Timestamp (0x26[5:4]) gets reset to 0b00, and the CEC Rx
Buffer 3 Ready bit (0x49[2]) also gets reset to 0b0. Timestamp values are only updated when a new frame arrives.
Once the host processes the recently arrived frame (or earlier frame arrivals), the host system must also clear the
corresponding CEC Rx Buffer Ready Interrupt bit (0x27[2:0] Main Map). See ▶Section 4.10 for details on using interrupts.
Clearing the CEC Rx Buffer Ready Interrupt bit (0x27[2:0] Main Map) causes the INT pin to go low thereby allowing the host
system to process other interrupts.
▶ Figure 29 to ▶Figure 31 illustrate the behavior of the CEC Rx Buffer Timestamp (0x26[5:0]) registers.

Rev G
PROGRAMMING GUIDE
Figure 29
ADV7511
CEC Receiver Timestamp Operation – Message Arrival
As shown ▶Figure 29, once messages arrive and fill up the three CEC Rx Buffers, timestamp values are assigned to the
corresponding CEC Rx Buffer Timestamp (0x26[5:0]) registers with the earliest arrival being assigned a value of 1, and later
arrivals being assigned incrementally higher integer values. In the example shown in ▶Figure 29, message “A” is the earliest
arrival at CEC Rx Buffer 1 and therefore CEC Rx Buffer 1 Timestamp (0x26[1:0]) assumes a value of ‘1’. Messages “B” and
“C” are subsequent arrivals and their corresponding timestamp registers assume values of ‘2’ and ‘3’ respectively.

CEC Receiver Timestamp Operation – Partial Message Processing
▶ Figure 30shows the status of the CEC Rx Buffer Timestamp registers once the corresponding messages have been
processed by the system host and the corresponding CEC Rx Buffer Ready Clear (0x4A[2:0]) bits have been toggled. As can
be seen in ▶ Figure 30, toggling the CEC Rx Buffer Ready Clear bit resets the respective timestamp value to ‘0’ and readies
the CEC Rx Buffer to receive a new message. Note that the corresponding CEC Rx Buffer Ready Interrupt (0x97[2:0] – Main
Map) also has to be cleared to cause the INT pin to go low and allow the system host to continue processing other system
interrupts.

ADV7511
CEC Receiver Timestamp Operation – New Message Arrival
▶Figure 31 shows the status of the CEC Rx Buffer Timestamps once new messages have arrived into the CEC Rx Buffers. As
seen in ▶Figure 31, the value of CEC Rx Buffer 3 timestamp is assigned a value of ‘1’, since it is the earliest available message.
The timestamp values corresponding to the new message arrivals at CEC Rx Buffers 1 and 2 are assigned values of ‘2’ and ‘3’
respectively.
▶ Figure 32 illustrates the state machine for control of the CEC message receiving process.

Handling CEC Initiators with non-compliant EOM
The CEC hardware does not check for an End of Message (EOM) signal to identify the end of a message. Instead the CEC Rx will
continue to buffer bytes until a “time out” occurs. This could cause a problem for the HDMI compliance test because bytes sent after
an EOM should be ignored.
The following procedure can be used to work around issues with non HDMI compliant CEC sources, which continue sending data
after the EOM signal.
1.
Read the message opcode in the corresponding Rx Frame Buffer register
2.
Check expected length of message in HDMI 1.4 Specification Supplement 1
3.
Compare expected length with length reported in the corresponding Rx Frame Buffer Frame Length register
4.
If the expected length is greater than the reported length, then use the expected length

4.9.4
Typical Operation Flow
4.9.4.1
CEC Acting as an Initiator:
Step 1
The host writes the message to the Tx Frame Header (0x00 CEC Memory Map) and Tx FrameData[0:14] registers. Then the
Tx Enable register (0x11[0] CECMemory Map) will be set to ‘1’ to enable the CEC Tx module.
Step 2
When CEC module detects that the host has set the Tx Enable signal to be valid, it will begin to send the message in the Tx
buffer after waiting for the signal free time. During the message transmission, if CEC bus arbitration is lost, CEC Tx module
will stop the transmission operation immediately and interrupt the host through setting Tx Arbitration Lost signal. If no
acknowledge signal is received or lowdrive is detected although TX has tried Tx Retry (0x12[6:4] CEC Memory Map) times,
the CEC Tx module will report that the transmission is failed through setting the interrupt signal of Tx Retry Timeout. If the
message transmission is successful, the Tx Ready interrupt signal will be set to notify the host.
Step 3
The host will be interrupted once the message has been completed whether it is successful of not. Then the host is responsible
for deciding what to do next according to the interrupt type. The Tx Nack Counter and Tx Lowdrive Counter show
complementary information to the host so that the host can know how many times the transmission has failed due to no
acknowledge and how many times the transmission has failed due to low drive. These two counters play an important role
during the operation of logical address allocation. In this situation, the host should process the following flow:
If (Tx Ready ==1)
This equality means that the logical address has been occupied by another CEC device. The host should give up this logical
address and try another logical address.
Else if (Tx Retry Timeout ==1)
If (Tx Nack Counter == Tx Retry +1)
This means that the logical address is an available address and can be allocated to the device containing the HDMI Tx.
Else
This means the CEC Tx transmission has failed (Tx Retry +1) times – because either the initiator has detected NO ACK or a
follower on the CEC bus has responded with a ”low drive” error.. In this situation, the host needs to keep this logical address
and try it again later.
Page 133 of 203
Rev G
PROGRAMMING GUIDE
ADV7511
Step 4
After confirming one of the three interrupts has occurred, Tx Enable has to be cleared, by writing ‘0’ to 0x11[0], to prepare for
the next transmission.
4.9.4.2
CEC Acts as a Follower:
Step 1
The host is ready to accept CEC messages on power-up.
Step 2
The CEC module will always monitor the CEC bus and accept broadcast messages or directly addressed messages. When any
message besides a polling message is completely buffered in one of the CEC Rx Buffers, the CEC Receiver module will assert
the corresponding CEC Rx Buffer Ready bit(0x49[2:0]) and the CEC Rx Buffer Ready Interrupt (0x97[2:0] Main map) bit will
be asserted. The order of arrival of a new frame in each buffer is assigned to three two-bit timestamp registers (0x96[5:0]).
Each timestamp register can assume a value between and including 0b01 and 0b11, depending on when a new frame arrives at
the corresponding CEC Rx Buffer. A value of 0b01 corresponds to the earliest arrived message and a value of 0b11
corresponds to the latest.
Step 3
The host responds to the Rx Ready interrupt, and the CEC message in the received buffer will be read out from CEC module
and delivered to the high-level software functions.
Step 4
After the interrupt handler has completed, the host system must clear the interrupt by setting the value of the corresponding
CEC Rx Buffer Ready Interrupt Clear (0x97[2:0] Main map) to ‘1’. It must then toggle the CEC Rx Buffer Ready Clear
(0xBA[2:0]) bit, which will clear the CEC Rx Buffer Ready (0xB9[2:0]) and also reset the value of the respective timestamp to
‘0’. Timestamp registers will be updated on arrival of a new data frame.
4.9.5
CEC System Control
4.9.6
CEC System Power and CDC Control
There is power-down bit, CEC PD, at register 0xE2 bit 0 in the main register map. This bit will reset all CEC logic and the
CEC I2C map. Note that if CEC is powered down then the CEC can no longer respond to CEC commands. Refer to the
“Additional Power Reduction Methods” section ▶ 4.8.2 for more details on the use of this bit.
The CEC Power Mode can be controlled by register bits 0x4E[1:0]. It can be always active, always powered down, or depend
on the status of HPD. To reset the CEC registers Soft Reset (0x50[0]), can be set to 1, then back to 0.
HDMI 1.4 defines special Capability Discover and Control message arbitration rules. These rules are enabled by default, and
can be disabled by setting the CDC Arbitration Enable register bit 0xF7[7] to 0. To automatically detect CDC messages the
Physical Address must be written in registers 0x80 and 0x81.
4.9.7
CEC Timing Control
The CEC module requires an input clock from 3MHz to 100MHz, the timing registers and clock divider need to be adjusted
based on the frequency of the input clock. The default settings for these registers are for a 12MHz input clock. If using an
alternate frequency, refer to the “CEC Clock Timing Calculator” spreadsheet, which can be obtained by contacting
[email protected] CEC timing register settings for the use of 3MHz, 13.5MHz, and 27MHz are provided
in ▶ Table 105, ▶ Table 106, and ▶ Table 107.

HDCP/EDID Controller
4.10.1
ADV7511 EDID/HDCP Support Features
The ADV7511’s EDID and DDC Controllerperforms three main functions to support the system’s EDID and HDCP
handling. These features are outlined below. A block diagram is illustrated in ▶ Figure 33.
■ Reads EDID segment 0 from the display as soon as Hot Plug is detected and the chip is set to powered up mode.
o
o
The 256-byte EDID segment is stored in internal RAM and can be read via I2C and has its own I2C address.
The I2C slave address of the EDID memory can be programmed in the EDID ID register (0x43). The default
value for this register is 0x7E.
Reads additional EDID segments on demand.
Page 143 of 203

PROGRAMMING GUIDE
o
ADV7511
These segments are stored in the same location as the first segment. Therefore, the controller should store the
first segment prior to initializing another EDID segment download.
■ Implements the HDCP transmitter state machine including handling of downstream repeaters.
■ Includes robust error reporting to report various error conditions to the system firmware.
▶ Figure 33 shows a flow chart of the State Machine implemented by the internal controller. Circles indicate functions that are
controlled automatically within the ADV7511, and squares indicate functions that must be implemented in the system software.

Interrupt Handling
The ADV7511 has interrupts to help with the system design. The interrupts allow the internal HDCP/EDID controller to
alert the system of the events listed in ▶ Table 110. For Hot Plug Detect and Monitor Sense, the interrupt will be triggered for
every transition, so the read-only register must be used to determine if the HPD or Monitor Sense is logic high or logic low.

Wake Up Opcodes
The Wake UpOpcode interrupts correspond to registers 0x77 – 0x7E in the CEC register map. When a user defined opcode
is detected in an incoming CEC message, the corresponding interrupt will be triggered.
4.11.2
Hot Plug Detect
This interrupt is triggered every time there is an HPD transition from high to low or low to high.
4.11.3
Monitor Sense
This interrupt is triggered every time the TMDS clock line voltages both cross 1.8V from high to low or low to high.
4.11.4
Active Vsync Edge
This interrupt is triggered whenever ADV7511 detects a Vsync leading edge. This applies to all input types. Vsync edge
detection is useful for timing some I2C writes such as enabling CSC and Gamut Metadata Packet information. See the
following sections for further information:
▶
▶
4.3.8.3 - Changing the Color Space with Active Display
4.3.9.3 - Gamut Metadata Packet
Page 145 of 203
Rev G
PROGRAMMING GUIDE
4.11.5
ADV7511
Audio FIFO Full
This interrupt is triggered if more data goes into the audio FIFO than comes out. If it happens at initialization period, it is not
a problem. If it happens after the system is fully configured, then there is a problem with the system.
4.11.6
Embedded Sync Parity Error
This interrupt is triggered when the embedded sync parity protection encounters two errors in F/V/H bits of EAV or SAV
bits. ADV7511 is able to correct a one-bit error and flag a two-bit error.
4.11.7
EDID Ready
This interrupt is triggered when the EDID has been read from the receiver and is available in the ADV7511 EDID memory to
be read at I2C address 0x7E (programmable). If the EDID Ready flag does not occur after EDID is expected, an I2C Error on
the HDCP Error interrupt will occur if enabled.
4.11.8
HDCP Authenticated
This interrupt occurs when the HDCP/EDID state machine transitions from state 3 to state 4. This means that the final BKSV
flag has been cleared and the host system has access to all of the downstream BKSVs. This means that authentication is
complete and it is now safe for the host to send copyrighted audio and video data across the HDCP-protected HDMI link.
4.11.9
HDCP Error
This interrupt is triggered when the HDCP/EDID Controller is reporting an error to the system software. The error which
occurred is represented by an error code contained in I2C register 0xC8[7:4].
4.11.10
BKSV Flag
This interrupt is triggered when KSVs from a downstream device are read into the ADV7511. If the BKSV count register
(0xC7[6:0]) is zero, then the 5 byte KSV from the receiver directly connected to the ADV7511 will be available in registers
0xBF – 0xC3. If the BKSV count register 1 or greater, then the specified amount of 5 byte KSVs from downstream devices will
be available in the EDID memory.
4.11.11
CECTx Ready Flag
This interrupt indicates that the CEC host is ready to transmit data.
4.11.12
CECTx Arbitration Lost Flag
This interrupt reflects the fact that the Tx was trying to transmit but lost a bus arbitration to another CEC device.
4.11.13
CECTx Retry Timeout Flag
This interrupt indicates that the Tx retried in excess of the limit programmed into the Tx_retry register (0x12[6:4]) of the CEC
memory block.
4.11.14
CEC Rx Ready Flags
This interrupt indicates that the CEC host is ready to monitor and receive data for a corresponding CEC Buffer.
▶147Figure 34 shows the process of detecting and clearing an interrupt. The interrupt pin and interrupt register become
active simultaneously when an event triggers an interrupt. The system software processes the interrupt, and then writes a ‘1’
to the interrupt register to clear the register and set the interrupt pin back to inactive. The pin will remain active until each
active interrupt register is cleared.

Masks are available to let the user selectively activate each interrupt. To enable a specific interrupt register, write 1 to the
corresponding mask bit. The mask bits will not affect the interrupt registers, only the interrupt pin. For some interrupts there
are read-only registers available for checking the state.

SECTION 5 - REGISTER MAPS
The ADV7511 contains four 256-byte register maps as described in section ▶ 4.1. The full details of each relevant address byte is
described in the following section. For each register map, addresses between 0x00 and 0xFF not included in the register map are not
affected by I2C writes and will always read ‘0’. The far right column of the following tables contain a linked reference to the
Programming Guide section that provides more detail as to the operation of the particular register being described.
