SECTION 1: INTRODUCTION
1.1
Scope and Organization
This document is intended to help the hardware designer understand what is necessary to design for the ADV7511 and
maintain the highest levels of performance. The ADV7511 Hardware User's Guide (HUG) provides guidelines to
design the schematics and board layout. Included are sections on the 100-lead LQFP package and an overview of the
functional blocks (including a brief description for each block) to provide an understanding of the ADV7511
functional and performance capabilities. The ADV7511 Programming Guide (PG) is available as a separate document
and should be used to gain a complete understanding on how to configure the ADV7511 within a system application.
It is divided into the following sections:
Section 2: Reference Documents is a list of other references, which will be helpful when designing with the
ADV7511 HDMI Transmitter.
Section 3: Block Diagram gives an overall functional view of the HDMI transmitter.
Section 4:Specifications give all pertinent data such as: timing, power and testing.
Section 5:Pin and Package Information give the mechanical details of the interface.
Section 6:Functional Description serves to elaborate on input, output and internal operations.
Section 7: PCB Layout Recommendations are an aid to low noise operation.

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.
Page 7 of 58
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.

6.1.1
Input Connections
Unused Inputs
Any input data signals which are not used should be connected to ground.
6.1.2
Video Data Capture Block
The ADV7511 can accept 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) to as many as 36 pins (RGB 4:4:4 or YCbCr 4:4:4). In addition it can accept HSYNC, VSYNC
and DE (Data Enable). The ADV7511 can detect all of the 59 video formats defined in the EIA/CEA-861D
specification. Either 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 center-justified. In the
case of center justification, the channel data is left-justified in their respective 12-bit fields. For example a centerjustified 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, see Figure 2. For complete details on how to set these, refer to the
ADV7511 Programming Guide.
The ADV7511 can accept HSYNC, VSYNC and DE (Data Enable) signals separately or as an embedded data (ITU 656
based) on the data inputs. If using separate syncs and DE is not available, the DE signal can be generated internally in
the ADV7511.
The tables in section 6.1.2.1 define how the many different formats are accepted on the input data lines.

Input ID = 1: An input with YCbCr 4:2:2 with separate syncs can be selected by setting the Input ID (R0x15[3:0]) to 0x1. The
data bit width (24, 20, or 16 bits) must be set with R0x16 [5:4]. The three input pin assignment styles are shown in the table. The
Input Style can be set in R0x16[3:2].
Input ID = 2: An input with YCbCr 4:2:2 with embedded syncs (SAV and EAV) can be selected by setting the Input ID
(R0x15[3:0]) to 0x2. The data bit width (24 = 12 bits, 20 = 10 bits, or 16 = 8 bits) must be set with R0x16 [5:4]. The three input pin
assignment styles are shown in the table. The Input Style can be set in R0x16[3:2]. The only difference between Input ID 1 and
Input ID 2 is that the syncs on ID 2 are embedded in the data much like an ITU 656 style bus running at 1X clock and double
width.

Input ID = 3: An input with YCbCr 4:2:2 data and separate syncs can be selected by setting the Input ID (R0x15[3:0]) to 0x3. The data bit width
(12, 10, or 8 bits) must be set with R0x16 [5:4]. The two input pin assignment styles are shown in the table. The Input Style can be set in
R0x16[3:2]. Pixel 1 is the first pixel of the 4:2:2 word and should be where DE starts. This mode requires an input clock 2X the pixel rate. For
timing details, see the ▷ ADV7511 Hardware User’s Guide and ▶ Figure 8.
Input ID = 4: An input with YCbCr 4:2:2 and embedded syncs (ITU 656 based) can be selected by setting the Input ID (R0x15[3:0]) to 0x4. The
data bit width (12, 10, or 8 bits) must be set with R0x16 [5:4]. The two input pin assignment styles are shown in the table. The Input Style can be
set in R0x16[3:2]. The order of data input is the order in the table. For example, data is accepted as: Cb0, Y0, Cr0, Y1, Cb2, Y2, Cr2, Y3… Pixel 1
is the first pixel of the 4:2:2 word and should be where DE starts. This mode requires an input clock 2X the pixel rate. For timing details, see
the ▷ ADV7511 Hardware User’s Guide and ▶ Figure 8.
Input ID=7: This input format is the same as input ID 3 with the exception that the clock is not 2X the pixel rate, but is double data rate (DDR) and the Input ID
(R0x15[3:0]) is set to 0x7. For timing details, see the ▷ ADV7511 Hardware User’s Guide and ▶Figure 9 and ▶ Figure 10. The 1st and the 2nd edge may be the rising
or falling edge. The Data Input Edge is defined in R0x16 [1]. 0b1 = 1st edge rising edge; 0b0 = 1st edge falling edge.
Input ID=8: This input format is the same as input ID 4 with the exception that the clock is not 2X the pixel rate, but is double data rate (DDR) and the Input ID

6.1.3.2
Inter-IC Sound (I2S) Audio
The ADV7511 can accommodate from two to eight channels of I2S audio at up to a 192KHz sampling rate. The
ADV7511 supports standard I2S, left-justified serial audio, right-justified serial audio and AES3 stream formats via
R0x0C[1:0] and sample word lengths between 16 bits and 24 bits (R0x14[3:0]).
If the I2S data changes on the rising clock edge it is recommended that it be latched into the ADV7511 on the falling
edge. If the I2S data changes on the falling clock edge, it is recommended that it be latched into the ADV7511 on the
rising edge. This can be specified by programming register R0x0B[6]. 0 = latch on the rising clock edge; 1 = latch on
the falling clock edge. For more information see the following figures:
▶ Figure 11 –▶ Figure 14 for format information
▶ Figure 3 for timing information
▷ Please refer to the ADV7511 Programming Guide for more information about configuring the audio.
The accurate transmission of audio depends upon an accurate SCLK and can be a function of the duty cycle of the
SCLK. ▶Table 18 specifies this duty cycle dependency. ‘N’ and ‘CTS’ values are used to reconstruct the audio data and
if the ‘N’ value is an odd number, the SCLK duty cycle must be within the range of 49 – 51%; if the ‘N’ value is an even
number and the audio is in a 32 bit format the SCLK duty cycle requirements can be in a much wider range of 40 –
60%. For the case of 16 bit audio format, ‘N’ values which are not divisible by 4 restrict the duty cycle to 49-51% where
an ‘N’ value which is evenly divisible by 4 may have a duty cycle from 40% - 60%.

Sony/Philips Digital Interface (SPDIF)
The ADV7511 is capable of accepting two-channel linear pulse code modulation (LPCM) and encoded audio up to a 192KHz
sampling rate via the SPDIF. SPDIF audio input is selected by setting R0x0A[4] = ‘1’. The ADV7511 is capable of accepting
SPDIF with or without an MCLK input. When no MCLK is present the ADV7511 generates its own MCLK internally
based on the SPDIF information to sample the data and determine the CTS value. For timing information see ▶Figure
4.

DSD Audio
Direct Stream Digital (DSD) Audio uses the One Bit Audio packets to transfer data across the Transition Minimized
Differential Signaling (TMDS) link. Up to eight channels of DSD data can be input onto eight data lines (DSD[5:0]
plus I2S3 and I2S2 if channels 7 and 8 are required) clocked by the DSD_CLK at 2.8224MHz. For timing information
see ▶Figure 5.
6.1.3.5
HBR Audio
High Bit-Rate audio uses the HBR audio packets to transfer compressed data at rates greater than 6.144Mbps across
the TMDS link. For additional information, refer to IEC61937.

DST Audio
Direct Stream Transfer audio is compressed DSD audio. This format is sent in frames which are in time slots equal to
1/75 of a second. The DST audio packets will be used to send the data across the TMDS link. Refer to ISO/IEC14496,
Part 3 for additional information.
6.1.4
Hot Plug Detect (HPD) pin
The Hot Plug Detect (HPD) pin is an input which detects if a DVI or HDMI sink is connected. If the voltage on HPD
is greater than 1.2V, then the ADV7511 considers an HDMI/DVI sink is connected. If the voltage is below 1.2V, then
the ADV7511 considers no sink is connected. The HPD must be connected to the HDMI connector. A 10KΩ (+/-10%)
pull down resistor to ground is recommended: this ensures that 0V is present on the HPD pin when no sink is
connected.
6.1.5
Power Down / I2C Address (PD/AD)
The Power Down / Address (PD/AD) input pin can be connected to GND or AVDD (through a 2KΩ (+/-10%) resistor
or a control signal). The device address and power down polarity are set by the state of the PD/AD pin when the
ADV7511 supplies are applied. For example, if the PD/AD pin is low (when the supplies are turned on) then the device
address will be 0x72 and the power down will be active high. If the PD/AD pin is high (when the supplies are turned
on), the device address will be 0x7A and the power down will be active low. The ADV7511 power state can also be
controlled via I2C registers (the PD pin and PD register bit are “or’ed” together). For further information, please refer
to the Power Management section of the ADV7511 Programming Guide.
6.1.6
Input Voltage Tolerance
The digital inputs (video, audio) on the ADV7511 work with 1.8V and 3.3V signal levels. The I2C ports
(DDCSDA/DDCSCL and SDA/SCL) and (Consumer Electronic Control) CEC port work with 1.8V and 3.3V and are
tolerant of 5V logic levels.
6.2
Audio Return Channel (ARC)
An HDMI v1.4 feature incorporated in the ADV7511 is HEAC (ARC). The Audio Return Channel is part of the HDMI
Ethernet Audio return Channel (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 differential signals are on the HEAC+ pin and the HEAC- pin. A single mode transmission will be on
the HEAC+ line. 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. These
represent a clock rate of respectively: 4.096MHz, 5.6448MHz and 6.144MHz.
Control of the ARC is initiated by the sink over the CEC lines. The capabilities of the source can be discovered in this
fashion with the TMDS sink driving the ARC line(s).

Unused ARC
If the ARC function is not to be used, the input pins (51 and 52) should be tied to ground.

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 as 3.3V CMOS logic levels. This is illustrated in ▶Figure 17. Refer to the ADV7511 Programming
Guide for more details concerning the setup and operation of the ARC receiver. The HEAC signals should be routed
from the HDMI connector as 100 ohm impedance differential traces, decoupled with a 1μF capacitor and terminated
with a 50 ohm (+/-1%) resistor to 1.8V.

TMDS Outputs
The three TMDS output data channels have signals which can run up to 2.25GHz. It is highly recommended to match
the length of the traces in order to minimize the following:
Intra-pair skew (skew between + and - )
Inter-pair skew (skew between Channels 0, 1, and 2 and Clock)
Page 41 of 58

The traces should also have a 50 Ohm transmission line impedance characteristic (100 Ohms differential). This is very
important to avoid any reflections, thus outputting the best Eye Diagram. Also minimize the trace length as much as
possible to minimize the resistance path. This is generally done by placing the ADV7511 close to the HDMI connector.
6.3.2.1
ESD Protection
In order to provide ESD protection to the TMDS differential pairs, it is recommended that low capacitance (<.6pF)
varistors are used, such as the Panasonic EZAEG2A device. Please refer to ▶Figure 27 for connection of the varistors.
These should be placed as close to the TMDS lines as possible.
6.3.2.2
EMI Prevention
If it is necessary to reduce the EMI emissions (predominantly at higher frequencies), we recommend use of common
mode chokes placed in the TMDS lines as close to the ADV7511 as is possible. Two such options are the Murata
DLW21SN670HQ2L (67 ohm) or DLW21SN900SHQ2 (90 ohm).
6.3.3
Display Data Channel (DDC) pins
The Display Data Channel (DDCSCL and DDCSDA) pins need to have the minimum amount of capacitance loading
to ensure the best signal integrity. The DDCSCL and DDCSDA capacitance loading must be less than 50pF to meet the
HDMI compliance specification. The DDCSCL and DDCSDA must be connected to the HDMI connector and a pullup resistor to 5V is required. The pull-up resistor must have a value between 1.5KΩ and 2KΩ. The Enhanced Display
Identification Data (EDID) EEPROM on the HDMI/DVI sink is expected to have an address of 0xA0. It is
recommended to match the length of the DDCSCL and DDCSDA lines.
6.3.4
Interrupt Output (INT)
The ADV7511 provides the INT (interrupt) pin in order to enable an interrupt driven system design. The interrupt pin
is an open drain output. It should be pulled to a logic high level (such as 1.8V or 3.3V depending on the high logic level
of the microcontroller) through a resistor (2kOhm to 5kOhm). It should also be connected to the input of the system’s
microcontroller. Refer to the ADV7511 Programming Guide for additional information.
6.3.5
PLL Circuit
The phase-locked loop (PLL) generates the TMDS output clock as well as clocks used internally by the ADV7511 to
serialize the data. The PLL filters high-frequency jitter components to minimize the output data clock jitter.

CEC Function
The ADV7511 has a Consumer Electronic Control (CEC) receiver/transmitter function which captures and buffers
three (3) command messages and passes them on to the host. CEC is a single-wire, bidirectional interface intended to
facilitate the control of any device on an HDMI network, as typified in ▶ Figure 18, with the remote control unit or ondevice 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 19 describes some typical end-user CEC features.
Figure 18
Table 19
Typical All-HDMI Home Theatre
Some useful “End-User” CEC Features:
Feature
Description
One-Touch Play
Pushing the “play” button commands a source to play and become the
active video source for the TV.
Stand-By
Pushing the “power down” button of any active device commands all
devices on the HDMI network to shut down.
One-Touch Record
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.
6.5
Video Data Formatting
Following the Input Data Capture are the options for Color Space Conversion (CSC) and for formatting between 4:4:4
and 4:2:2. Taken together these can alter an input stream from: RGB to YCbCr (4:4:4 or 4:2:2) , or YCbCr to RGB.
Required video control signals such as Hsync, Vsync and Data Enable (DE) can be generated from different input
formats and can be adjusted for optimum position.

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 19 for a block
diagram of the sync processing capabilities.
Separate Hsync, Vsync, and DE
For this method, all necessary signals are provided so neither Sync generation nor DE generation is required. If
desired, the 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.
▷ Refer to the ADV7511 Programming Guide for details on how to adjust the DE and sync timing.
Embedded Syncs (SAV and EAV)
When embedded syncs are provided to the ADV7511 Hsync and Vsync need to be generated internally by the
ADV7511 hardware. 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.
▷ Refer to the ADV7511 Programming Guide for details on how to program the DE and sync generator when
embedded syncs are used.
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.
▷ Refer to the ADV7511 Programming Guide for details on how to generate DE based on the incoming sync
signals.

Color Space Conversion (CSC) Matrix
The Color Space Conversion (CSC) matrix in the ADV7511 consists of three identical processing channels (see
▶Figure 20). In each channel, the three input values (R,G,B or Y,Cr,Cb - see ▶Table 20) are multiplied by three
separate coefficients. In each CSC channel, the order of input remains the same – Out_A will have the same input
(In_A, In_B, In_C) as Out_B and Out_C. The coefficients will be different for each channel. Also included is an offset
value for each row of the matrix and a scaling multiple for all values. Each coefficient is 13 bit 2’s complement
resolution to ensure the signal integrity is maintained. The CSC is designed to run at speeds up to 165Mhz, supporting
resolutions up to 1080p at 60Hz and UXGA at 60Hz. With “any-to-any” color space support, formats such as RGB,
YUV, YCbCr, and others are supported by the CSC.

The 4:2:2 to 4:4:4 conversion block can convert 4:2:2 input signals into the 4:4:4 timing format. This is necessary, for
instance, if the ADV7511 is set in DVI mode and has 4:2:2 format as its video input. The ADV7511 is also capable of
performing 4:4:4 to 4:2:2 conversions.
▷ Please refer to Section 4.3.5 of the ADV7511 Programming Guide for more information about this block.
6.6
DDC Controller
The ADV7511 DDC Controller performs two main functions: support the system’s EDID and handle HDCP.
• The ADV7511 has the ability to read and buffer the sink EDID (one segment of 256 bytes at a time) via
the DDC lines. This feature eliminates the requirement for the source controller to interface directly to
the sink.
• The ADV7511 DDC controller provides the path through which HDCP content protection
authentication and communications occur. The ADV7511 has internal HDCP key storage (eliminating
the need for an external EEPROM) and a built-in micro-controller to handle HDCP transmitter states,
including handling down-stream HDCP repeaters. This provides content protection for video which
prevents unauthorized digital copying. Refer to Section ▶ 6.8.2 for power consumption of HDCP.

Inter-IC Communications (I2C)
6.7.1
Two-Wire Serial Control Port
The ADV7511’s registers must be programmed through the SDA and SCL pins using the Inter IC (IIC or I2C)
protocol. The SDA/SCL programming address is 0x72 or 0x7A based on whether the PD/AD pin is pulled high (I2C
address = 0x7A) or pulled low (I2C address = 0x72). When initially powered up, there is a 200ms period before the
device is ready to be addressed.
▷ The ADV7511 Programming Guide provides the information necessary for programming the transmitter.
Up to two ADV7511 devices can be connected to the two-wire serial interface, with a unique address for each device.
The two-wire serial interface comprises a clock (SCL) and a bidirectional data (SDA) pin. The ADV7511 interface acts
as a slave for receiving and transmitting data over the serial interface. When the serial interface is not active, the logic
levels on SCL and SDA are pulled high by external pull-up resistors.
Data received or transmitted on the SDA line must be stable for the duration of the positive-going SCL pulse. Data on
SDA must change only when SCL is low. If SDA changes state while SCL is high, the serial interface interprets that
action as a start or stop sequence.
There are six components to serial bus operation:
■
■
■
■
■
■
Start signal
Slave address byte
Base register address byte
Data byte to read or write
Stop signal
Acknowledge (Ack)
When the serial interface is inactive (SCL and SDA are high), communications are initiated by sending a start signal.
The start signal is a high-to-low transition on SDA while SCL is high. This signal alerts all slaved devices that a data
transfer sequence is coming.
The first eight bits of data transferred after a start signal comprise a seven bit slave address (the first seven bits) and a
single R/W bit (the eighth bit). The R/W bit indicates the direction of data transfer, read from (1) or write to (0) the
slave device. If the transmitted slave address matches the address of the device (set by the state of the A2 input pin as
shown in Table 21), the ADV7511 acknowledges by bringing SDA low on the 9th SCL pulse. If the addresses do not
match, the ADV7511 does not acknowledge.

Data Transfer via I2C
For each byte of data read or written, the most significant bit (MSB) is the first bit of the sequence.
If the ADV7511 does not acknowledge the master device during a write sequence, the SDA remains high so the master
can generate a stop signal. If the master device does not acknowledge the ADV7511 during a read sequence, the
ADV7511 interprets this as end of data. The SDA remains high, so the master can generate a stop signal.
Writing data to specific control registers of the ADV7511 requires that the 8-bit address of the control register of
interest be written after the slave address has been established. This control register address is the base address for
subsequent write operations, however, it is reset after a STOP signal. The base address auto-increments by one for each
byte of data written after the data byte intended for the base address. If more bytes are transferred than there are
available addresses, the address does not increment and remains at its maximum value. Any base address higher than
the maximum value does not produce an acknowledge signal.
Data are read from the control registers of the ADV7511 in a similar manner. Reading requires two data transfer
operations:
1.
2.
The base address must be written with the R/W bit of the slave address byte low to set up a sequential read
operation.
Reading (the R/W bit of the slave address byte high) begins at the previously established base address. The
address of the read register auto-increments after each byte is transferred.
To terminate a read/write sequence to the ADV7511, a stop signal must be sent. A stop signal comprises a low-to-high
transition of SDA while SCL is high. As in the write sequence, a STOP signal resets the base address.
A repeated start signal occurs when the master device driving the serial interface generates a start signal without first
generating a stop signal to terminate the current communication. This is used to change the mode of communication
(read/write) between the slave and master without releasing the serial interface lines.

Power Domains
The AVDD, DVDD, PVDD, BGVDD and PLVDD power domains of the ADV7511 operate off of 1.8 volts. It is

and which functional blocks are being used. In Section 4: the specifications table lists the maximum power as 326mW
at 1080p, CSC off. ▶ Table 22illustrates the maximum power consumed by individual circuits in the ADV7511. All of

SECTION 7: PCB LAYOUT RECOMMENDATIONS
7.1
Power Supply Filtering
All of the ADV7511 supply domains are 1.8V with the exception of MVDD which is 3.3V and need to remain as noisefree as possible for the best operation. Power supply noise has a frequency component that affects performance, and
this is specified in Vrms terms. ▶Figure 24 shows the maximum allowable noise for the AVDD and PLVDD supply
domains in the ADV7511. The noise limit for all other supply domains are listed in ▶ Table 1.
It is recommended to combine the five 1.8 volt power domains of the ADV7511 into 3 separate PCB power domains as
shown in ▶Figure 23. An LC filter on the output of the power supply is recommended to attenuate the noise and
should be placed as close to the ADV7511 as possible. An effective LC filter for this is a 10 μH inductor and a 10μF
capacitor (see▶ Figure 23). This filter scheme will reduce any noise component over 20KHz to effectively 0. Using the
recommended LC filter with realistic load and series resistance yields the transfer curve shown in Figure 25.
Each of the power supply pins of the ADV7511 should also have a 0.1uF capacitor connected to the ground plane as
shown in ▶Figure 23. The capacitor should be placed as close to the supply pin as possible. Adjacent power pins can
share a bypass capacitor. The ground pins of the ADV7511 should be connected to the GND plane using vias.

LC Filter Transfer Curve
Video Clock and Data Inputs
Any noise that that is coupled onto the CLK input trace will add jitter to the system. It is a recommended to control the
impedance of the CLK trace. If possible, using a solid ground or supply reference under the trace is a good way to
ensure the impedance remains constant over the entire length of the trace. Therefore, minimize the video input data
clock (pin 79) trace length and do not run any digital or other high frequency traces near it. Make sure to match the
length of the input data signals to optimize data capture especially for Double Data Rate (DDR) input formats.
7.3
Audio Clock and Data Inputs
The length of the input audio data signals should be matched as closely as possible to optimize audio data capture. It is
recommended to add series 50Ω resistors (+/-5%) as close as possible to the source of the audio data and clock signals
to minimize impedance mismatch.
7.4
SDA and SCL
The SDA and SCL pins should be connected to an I2C Master. A pull-up resistor of 2KΩ (+/-5%) to 1.8V or 3.3V is
recommended for each of these signals. See Figure 27.

7.5
DDCSDA and DDCSCL
The DDCSDA and DDCSCL pins should be connected to the HDMI connector. A pull-up resistor of 1.5KΩ to 2KΩ
(+/-5%) to HDMI +5V is required for each of these signals. See Figure 27.

7.6
Current Reference Pin: R_EXT
The external reference resistor should be connected between the R_EXT pin and ground with as short a trace as
possible. The external reference resistor must have a value of 887 Ohms (+/-1% tolerance). It is strongly recommended
to avoid running any high-speed AC or noisy signals next to the R_EXT line or close to it. Specifically it is
recommended that no switching signals – such as LRCLK (including vias) be routed close to the R_EXT pin (28). Lowlevel TMDS switching noise should have minimal impact on R_EXT.
7.7
CEC Implementation
An external clock is required to drive the CEC_CLK input pin. Default frequency is 12MHz, but any clock between 3
and 100MHz (+/-2%) can be used. ▶Figure 26 illustrates the recommended connection to the CEC line.

ARC
Audio Return Channel
CEC
Consumer Electronics Control is used to unify remotes of differing make to perform a given task with onebutton- touch.
CSC
Colorspace Convert is used to convert RGB to YCbCbr or YCbCr to RGB. Adjustments can be factored in
for differing ranges.
DDC
Display Data Channel is used to communicate between to the source and sink to determine sink
capabilities. It is also used as the HDCP key communications channel.
DDR
Double Data Rate clocks capture data on both the rising and falling edge of the clock.
Deep Color
Deep Color™ is a feature of HDMI v.1.3 in which pixel color depths for 444 signals can be greater the 8 bits.
Options exist for 10, 12, and 16 bits.
DSD
Direct Stream Digital audio is transmitted in a one-bit delta sigma audio stream.
DST
Direct Stream Transfer is a lossless compression technique for DSD audio
DVI
Digital Visual Interface - uses TMDS to transmit RGB signals.
EDID
Enhanced Display Identification Data is used to store monitor (sink) capabilities in an EEPROM.
HBR
High Bit-Rate audio is used to define sample rates greater than 192Kbits.
HDCP
High-bandwidth Digital Content Protection is a method of protecting content from unauthorized digital
copying.
HDMI
High Definition Multimedia Interface is composed of three TMDS differential data channels and one
differential clock channel. It is defined to include video streams up to 3.7Gbps as well as audio.
HEAC
HDMI Ethernet and Audio return Channel
HPD
The Hot Plug Detect pin is an input which detects if a DVI or HDMI sink is connected.
I2C, IIC
Inter-IC Communications is a Philips two-wire serial bus for low-speed (up to 400kHz) data.
I2S
Inter-IC Sound is a serial Philips bus designed specifically for audio.
LPCM
Linear Pulse-Code Modulation is a method of encoding audio samples.
LQFP
Low-Profile Quad Flat Pack is the type of package for the ADV7511.
NDA
Non-Disclosure Agreement is used to assure confidentiality of intellectual property.
PLL
Phase-Locked Loop.
RGB
Red Green Blue is the standard definition for three-color graphics and video.

TMDS
Transition Minimized Differential Signaling is the format used by the three data channels in HDMI. This
encodes 8 bits into 10 and serializes them.
x.v.Color™
This is feature of HDMI v.1.3 in which the color gamut may be extended or altered beyond the normal
range in order to accommodate a given sink.
YCbCr
This is a common color format for video where the ‘Y’ component is luminance and the Cr and Cb signals
are color difference signals. 4:4:4 defines a Y, Cr, and Cb for each pixel; 4:2:2 defines a Y for each pixel and
a sharing of Cr and Cb between 2 sequential pixels. In this manner, compression of 33% is possible.
I2C refers to a communications protocol originally developed by Philips Semiconductors (now NXP Semiconductors).
