GENERAL DESCRIPTION
The ADV7340/ADV7341 are high speed, digital-to-analog
video encoders in a 64-lead LQFP package. Six high speed,
NSV, 3.3 V, 12-bit video DACs provide support for composite
(CVBS), S-Video (Y/C), and component (YPrPb/RGB) analog
outputs in either standard definition (SD), enhanced definition
(ED), or high definition (HD) video formats.
The ADV7340/ADV7341 each have a 30-bit pixel input port
that can be configured in a variety of ways. SD video formats
are supported over a SDR interface and ED/HD video formats
are supported over SDR and DDR interfaces. Pixel data can be
supplied in either the YCrCb or RGB color spaces.
The parts also support embedded EAV/SAV timing codes,
external video synchronization signals, and I2C and SPI
communication protocols.
In addition, simultaneous SD and ED/HD input and output are
supported. 216 MHz (SD and ED) and 297 MHz (HD)
oversampling ensures that external output filtering is not
required, while full-drive DACs ensure that external output
buffering is not required.
Cable detection and DAC auto power-down features keep
power consumption to a minimum.
Table 1 lists the video standards directly supported by the
ADV7340/ADV7341.

MPU PORT DESCRIPTION
Devices such as a microprocessor can communicate with the
ADV7340/ADV7341 through one of the following protocols:
•
•
2-wire serial (I2C-compatible) bus
4-wire serial (SPI-compatible) bus
After power-up or reset, the MPU port is configured for I2C
operation. SPI operation can be invoked at any time by
following the procedure outlined in the SPI Operation section.
I2C OPERATION
The ADV7340/ADV7341 support a 2-wire serial (I2Ccompatible) microprocessor bus driving multiple peripherals.
This port operates in an open-drain configuration. Two inputs,
serial data (SDA) and serial clock (SCL), carry information
between any device connected to the bus and the ADV7340/
ADV7341. Each slave device is recognized by a unique address.
The ADV7340/ADV7341 have four possible slave addresses for
both read and write operations. These are unique addresses for
each device and are illustrated in Figure 48. The LSB either sets a
read or write operation. Logic 1 corresponds to a read operation,
while Logic 0 corresponds to a write operation. A1 is controlled
by setting the ALSB/SPI_SS pin of the ADV7340/ADV7341 to
Logic 0 or Logic 1.

CONTROL
Figure 48. ADV7340 Slave Address = 0xD4 or 0xD6
line low during the ninth clock pulse. This is known as an
acknowledge bit. All other devices withdraw from the bus at
this point and maintain an idle condition. The idle condition
occurs when the device monitors the SDA and SCL lines
waiting for the start condition and the correct transmitted
address. The R/W bit determines the direction of the data.
Logic 0 on the LSB of the first byte means that the master writes
information to the peripheral. Logic 1 on the LSB of the first byte
means that the master reads information from the peripheral.
The ADV7340/ADV7341 act as a standard slave device on the
bus. The data on the SDA pin is eight bits long, supporting the
7-bit addresses plus the R/W bit. It interprets the first byte as
the device address and the second byte as the starting
subaddress. There is a subaddress auto-increment facility. This
allows data to be written to or read from registers in ascending
subaddress sequence starting at any valid subaddress. A data
transfer is always terminated by a stop condition. The user can
also access any unique subaddress register on a one-by-one
basis without updating all the registers.
Stop and start conditions can be detected at any stage during
the data transfer. If these conditions are asserted out of
sequence with normal read and write operations, they cause an
immediate jump to the idle condition. During a given SCL high
period, the user should issue only a start condition, a stop
condition, or a stop condition followed by a start condition. If
an invalid subaddress is issued by the user, the ADV7340/
ADV7341 do not issue an acknowledge and do return to the idle
condition. If the user utilizes the auto-increment method of
addressing the encoder and exceeds the highest subaddress, the
following actions are taken:
•
To control the various devices on the bus, use the following
protocol. The master initiates a data transfer by establishing a
start condition, defined by a high-to-low transition on SDA
while SCL remains high. This indicates that an address/data
stream follows. All peripherals respond to the start condition
and shift the next eight bits (7-bit address + R/W bit). The bits
are transferred from MSB down to LSB. The peripheral that
recognizes the transmitted address responds by pulling the data
•
Rev. 0 | Page 26 of 88
In read mode, the highest subaddress register contents are
output until the master device issues a no acknowledge.
This indicates the end of a read. A no acknowledge
condition occurs when the SDA line is not pulled low on
the ninth pulse.
In write mode, the data for the invalid byte is not loaded
into any subaddress register, a no acknowledge is issued by
the ADV7340/ADV7341, and the parts return to the idle
condition.

SPI OPERATION
The ADV7340/ADV7341 support a 4-wire serial (SPIcompatible) bus connecting multiple peripherals. Two inputs,
master out slave in (MOSI) and serial clock (SCLK), and one
output, master in slave out (MISO), carry information between
a master SPI peripheral on the bus and the ADV7340/ADV7341.
Each slave device on the bus has a slave select pin that is
connected to the master SPI peripheral by a unique slave select
line. As such, slave device addressing is not required.
To invoke SPI operation, a master SPI peripheral (for example,
a microprocessor) should issue three low pulses on the ADV7340/
ADV7341 ALSB/SPI_SS pin. When the encoder detects the
third rising edge on the ALSB/SPI_SS pin, it automatically
switches to SPI communication mode. The ADV7340/ADV7341
remain in SPI communication mode until a reset or powerdown occurs.
To control the ADV7340/ADV7341, use the following protocol
for both read and write transactions. First, the master initiates a
data transfer by driving and holding the ADV7340/ADV7341
ALSB/SPI_SS pin low. On the first SCLK rising edge after
ALSB/SPI_SS has been driven low, the write command, defined
as 0xD4, is written to the ADV7340/ADV7341 over the MOSI
line. The second byte written to the MOSI line is interpreted as
the starting subaddress. Data on the MOSI line is written MSB
first and clocked on the rising edge of SCLK.
There is a subaddress auto-increment facility. This allows data
to be written to or read from registers in ascending subaddress
sequence starting at any valid subaddress. The user can also
access any unique subaddress register on a one-by-one basis.
In a write data transfer, 8-bit data bytes are written to the
ADV7340/ADV7341, MSB first, on the MOSI line immediately
after the starting subaddress. The data bytes are clocked into
the ADV7340/ADV7341 on the rising edge of SCLK. When all
data bytes have been written, the master completes the transfer
by driving and holding the ADV7340/ADV7341 ALSB/SPI_SS
pin high.
In a read data transfer, after the subaddress has been clocked
in on the MOSI line, the ALSB/SPI_SS pin is driven and held
high for at least one clock cycle. Then, the ALSB/SPI_SS pin is
driven and held low again. On the first SCLK rising edge after
ALSB/SPI_SS has been driven low, the read command, defined
as 0xD5, is written, MSB first, to the ADV7340/ADV7341 over
the MOSI line. Subsequently, 8-bit data bytes are read from the
ADV7340/ADV7341, MSB first, on the MISO line. The data
bytes are clocked out of the ADV7340/ADV7341 on the falling
edge of SCLK. When all data bytes have been read, the master
completes the transfer by driving and holding the ADV7340/
ADV7341 ALSB/SPI_SS pin high.

REGISTER MAP ACCESS
A microprocessor can read from or write to all registers of the
ADV7340/ADV7341 via the MPU port, except for registers that
are specified as read-only or write-only registers.
The subaddress register determines which register the next
read or write operation accesses. All communication through
the MPU port starts with an access to the subaddress register.
A read/write operation is then performed from/to the target
address, which increments to the next address until the
transaction is complete.
REGISTER PROGRAMMING
Table 14 to Table 28 describe the functionality of each register.
All registers can be read from as well as written to, unless
otherwise stated.
SUBADDRESS REGISTER (SR7 TO SR0)
The subaddress register is an 8-bit write-only register. After the
MPU port is accessed and a read/write operation is selected, the
subaddress is set up. The subaddress register determines to or
from which register the operation takes place.

ADV7340/ADV7341
INPUT CONFIGURATION
The ADV7340/ADV7341 support a number of different input
modes. The desired input mode is selected using Subaddress
0x01, Bits[6:4]. The ADV7340/ADV7341 default to standard
definition only (SD only) upon power-up. Table 31 provides an
overview of all possible input configurations. Each input mode
is described in detail in the following sections.
In 16-/20-bit 4:2:2 YCrCb input mode, the Y pixel data is input
on Pin S9 to Pin S2/S0 (or Pin Y9 to Pin Y2/Y0, depending on
Subaddress 0x01, Bit 7), with S0/Y0 being the LSB in 20-bit
input mode.
The CrCb pixel data is input on Pin Y9 to Pin Y2/Y0 (or Pin C9
to Pin C2/C0, depending on Subaddress 0x01, Bit 7), with
Y0/C0 being the LSB in 20-bit input mode.
STANDARD DEFINITION ONLY
Subaddress 0x01, Bits[6:4] = 000
24-/30-Bit 4:4:4 RGB Mode
Subaddress 0x87, Bit 7 = 1
Standard definition (SD) YCrCb data can be input in 4:2:2 format.
Standard definition (SD) RGB data can be input in 4:4:4 format.
In 24-/30-bit 4:4:4 RGB input mode, the red pixel data is input on
Pin S9 to Pin S2/S0, the green pixel data is input on Pin Y9 to
Pin Y2/Y0, and the blue pixel data is input on Pin C9 to Pin C2/C0.
S0, Y0, and C0 are the respective bus LSBs in 30-bit input mode.
A 27 MHz clock signal must be provided on the CLKIN_A pin.
Input synchronization signals are provided on the S_HSYNC
and S_VSYNC pins.

ADV7340/ADV7341
FEATURES
OUTPUT OVERSAMPLING
The ADV7340/ADV7341 include two on-chip phase locked
loops (PLLs) that allow for oversampling of SD, ED, and HD
video data. Table 36 shows the various oversampling rates
supported in the ADV7340/ADV7341.
SD Only, ED Only, and HD Only Modes
PLL 1 is used in SD only, ED only, and HD only modes. PLL 2 is
unused in these modes. PLL 1 is disabled by default and can be
enabled using Subaddress 0x00, Bit 1 = 0.
SD and ED/HD Simultaneous Modes
Both PLL 1 and PLL 2 are used in simultaneous modes. The use
of two PLLs allows for independent oversampling of SD and
ED/HD video. PLL 1 is used to oversample SD video data, and
PLL 2 is used to oversample ED/HD video data. In simultaneous
modes, PLL 2 is always enabled. PLL 1 is disabled by default and
can be enabled using Subaddress 0x00, Bit 1 = 0.
ED/HD nonstandard timing mode can be enabled by setting
Subaddress 0x30, Bits[7:3] to 00001.
A clock signal must be provided on the CLKIN_A pin.
P_HSYNC and P_VSYNC must be toggled by the user to
generate the appropriate horizontal and vertical synchronization
pulses on the analog output from the encoder. Figure 59 illustrates
the various output levels that can be generated. Table 37 lists the
transitions required to generate these output levels.
Embedded EAV/SAV timing codes are not supported in
ED/HD nonstandard timing mode.
The user must ensure that appropriate pixel data is applied to
the encoder where the blanking level is expected at the output.

ED/HD TIMING RESET
Subcarrier Phase Reset (SCR) Mode
Subaddress 0x34, Bit 0
In this mode (Subaddress 0x84, Bits[2:1] = 01), a low-to-high
transition on the SFL/MISO pin (Pin 48) resets the subcarrier
phase to 0 on the field following the subcarrier phase reset. This
reset signal must be held high for a minimum of one clock cycle.
An ED/HD timing reset is achieved by toggling the ED/HD
timing reset control bit (Subaddress 0x34, Bit 0) from 0 to 1.
In this state, the horizontal and vertical counters remain reset.
When this bit is set back to 0, the internal counters resume
counting. This timing reset applies to the ED/HD timing
counters only.
Because the field counter is not reset, it is recommended that
the reset signal be applied in Field 7 (PAL) or Field 3 (NTSC).
The reset of the phase then occurs on the next field, that is,
Field 1, lined up correctly with the internal counters. The field
count register at Subaddress 0xBB can be used to identify the
number of the active field.
SD SUBCARRIER FREQUENCY LOCK, SUBCARRIER
PHASE RESET, AND TIMING RESET
Subaddress 0x84, Bits[2:1]
Subcarrier Frequency Lock (SFL) Mode
Together with the SFL/MISO pin and SD Mode Register 4
(Subaddress 0x84, Bits[2:1]), the ADV7340/ADV7341 can be used
in timing reset mode, subcarrier phase reset mode, or SFL mode.
In this mode (Subaddress 0x84, Bits[2:1] = 11), the ADV7340/
ADV7341 can be used to lock to an external video source. The
SFL mode allows the ADV7340/ADV7341 to automatically alter
the subcarrier frequency to compensate for line length
variations. When the part is connected to a device such as an
ADV7403 video decoder (see Figure 62) that outputs a digital
data stream in the SFL format, the part automatically changes to
the compensated subcarrier frequency on a line-by-line basis.
This digital data stream is 67 bits wide, and the subcarrier is
contained in Bit 0 to Bit 21. Each bit is two clock cycles long.
Timing Reset (TR) Mode
In this mode (Subaddress 0x84, Bits[2:1] = 10), a timing reset is
achieved in a low-to-high transition on the SFL/MISO pin (Pin 48).
In this state, the horizontal and vertical counters remain reset.
Upon releasing this pin (set to low), the internal counters resume
counting, starting with Field 1, and the subcarrier phase is reset.
The minimum time the pin must be held high is one clock
cycle; otherwise, this reset signal might not be recognized. This
timing reset applies to the SD timing counters only.

SD VCR FF/RW SYNC
Subaddress 0x82, Bit 5
In DVD record applications where the encoder is used with a
decoder, the VCR FF/RW sync control bit can be used for nonstandard input video, that is, in fast forward or rewind modes.
For the SMPTE 293M (525p) standard, VBI data can be
inserted on Line 13 to Line 42 of each frame, or on Line 6 to
Line 43 for the ITU-R BT.1358 (625p) standard.
VBI data can be present on Line 10 to Line 20 for NTSC and on
Line 7 to Line 22 for PAL.
In fast forward mode, the sync information at the start of a new
field in the incoming video usually occurs before the correct
number of lines/fields is reached. In rewind mode, this sync
signal usually occurs after the total number of lines/fields is
reached. Conventionally, this means that the output video has
corrupted field signals because one signal is generated by the
incoming video and another is generated when the internal
line/field counters reach the end of a field.
In SD Timing Mode 0 (slave option), if VBI is enabled, the
blanking bit in the EAV/SAV code is overwritten. It is possible
to use VBI in this timing mode as well.
When the VCR FF/RW sync control is enabled (Subaddress 0x82,
Bit 5), the line/field counters are updated according to the
incoming VSYNC signal and when the analog output matches
the incoming VSYNC signal.
Four 8-bit registers are used to set up the subcarrier frequency.
The value of these registers is calculated using:
This control is available in all slave-timing modes except Slave
Mode 0.

nevertheless available at the output.

Programming the FSC
The subcarrier frequency register value is divided into four FSC
registers, as shown in the previous example. The four subcarrier
frequency registers must be updated sequentially, starting with
Subcarrier Frequency Register 0 and ending with Subcarrier
Frequency Register 3. The subcarrier frequency updates only
after the last subcarrier frequency register byte has been
received by the ADV7340/ADV7341.

SD NONINTERLACED MODE
Subaddress 0x88, Bit 1
The ADV7340/ADV7341 support a SD noninterlaced mode.
Using this mode, progressive inputs at twice the frame rate of
NTSC and PAL (240p/59.94 Hz and 288p/50 Hz, respectively)
A 27 MHz clock signal must be provided on the CLKIN_A pin.
Embedded EAV/SAV timing codes or external horizontal and
vertical synchronization signals provided on the S_HSYNC and
S_VSYNC pins can be used to synchronize the input pixel data.
All input configurations, output configurations and features
available in NTSC and PAL modes are available in SD
noninterlaced mode.
For 240p/59.94 Hz input, the ADV7340/ADV7341 should be
configured for NTSC operation and Subaddress 0x88, Bit 1
should be set to 1.
For 288p/50 Hz input, the ADV7340/ADV7341 should be
configured for PAL operation and Subaddress 0x88, Bit 1
should be set to 1.
SD SQUARE PIXEL MODE
Subaddress 0x82, Bit 4
The ADV7340/ADV7341 can be used to operate in square pixel
mode (Subaddress 0x82, Bit 4). For NTSC operation, an input
clock of 24.5454 MHz is required. Alternatively, for PAL
operation, an input clock of 29.5 MHz is required. The internal
timing logic adjusts accordingly for square pixel mode
operation. In square pixel mode, the timing diagrams shown in
Figure 63 and Figure 64 apply.

SD Internal Filter Response
Subaddress 0x80, Bits[7:2]; Subaddress 0x82, Bit 0
The Y filter supports several different frequency responses,
including two low-pass responses, two notch responses, an
extended (SSAF) response with or without gain boost
attenuation, a CIF response, and a QCIF response. The PrPb
filter supports several different frequency responses, including
six low-pass responses, a CIF response, and a QCIF response, as
shown in Figure 39 and Figure 40.
If SD SSAF gain is enabled (Subaddress 0x87, Bit 4), there are 13
response options in the −4 dB to +4 dB range. The desired response
can be programmed using Subaddress 0xA2. The variation of
frequency responses is shown in Figure 36 to Figure 38.
In addition to the chroma filters listed in Table 39, the ADV7340
/ADV7341 contain an SSAF filter specifically designed for the
color difference component outputs, Pr and Pb. This filter has a
cutoff frequency of ~2.7 MHz and a gain of –40 dB at 3.8 MHz
(see Figure 65). This filter can be controlled with Subaddress
0x82, Bit 0.

ED/HD Manual CSC Matrix Adjust Feature
The ED/HD manual CSC matrix adjust feature provides custom
coefficient manipulation for color space conversions and is used
in ED and HD modes only. The ED/HD manual CSC matrix
adjust feature can be enabled using Subaddress 0x02, Bit 3.
Normally, there is no need to enable this feature because the CSC
matrix automatically performs the color space conversion based
on the input mode chosen (ED or HD) and the input and output
color spaces selected (see Table 43). For this reason, the ED/HD
manual CSC matrix adjust feature is disabled by default.
Rev. 0 | Page 54 of 88
ADV7340/ADV7341
If RGB output is selected, the ED/HD CSC matrix scalar uses
the following equations:
R = GY × Y + RV × Pr
GY, GU, GV, BU, and RV must be adjusted according to this
input standard color space. The user should consider that the
color component conversion could use different scale values.
G = GY × Y − (GU × Pb) − (GV × Pr)
For example, SMPTE 293M uses the following conversion:
R = Y + 1.402Pr
B = GY × Y + BU × Pb
Note that subtractions are implemented in hardware.
G = Y – 0.714Pr – 0.344Pb
If YPrPb output is selected, the following equations are used:
B = Y + 1.773Pb
Pr = RV × Pr

pixel data and is not functional when internal test patterns are
enabled.

SD LUMA AND COLOR CONTROL
Subaddress 0x9C to Subaddress 0x9F
SD Y Scale, SD Cb Scale, and SD Cr Scale are three 10-bit
control registers that scale the SD Y, Cb, and Cr output levels.
When the ED/HD manual CSC matrix adjust feature is enabled,
the default coefficient values in Subaddress 0x03 to Subaddress 0x09 are correct for the HD color space only. The color
components are converted according to the following 1080i and
720p standards (SMPTE 274M, SMPTE 296M):
Each of these registers represents the value required to scale the
Cb or Cr level from 0.0 to 2.0 times its initial value and the
Y level from 0.0 to 1.5 times its initial level. The value of these
10 bits is calculated using the following equation:
Y, Cb, or Cr Scale Value = Scale Factor × 512
For example, if Scale Factor = 1.3
R = Y + 1.575Pr
Y, Cb, or Cr Scale Value = 1.3 × 512 = 665.6
G = Y − 0.468Pr − 0.187Pb
Y, Cb, or Cr Scale Value = 666 (rounded to the nearest integer)
B = Y + 1.855Pb
Y, Cb, or Cr Scale Value = 1010 0110 10b
The conversion coefficients should be multiplied by 315 before
being written to the ED/HD CSC matrix registers. This is
reflected in the default values for GY = 0x13B, GU = 0x03B,
GV = 0x093, BU = 0x248, and RV = 0x1F0.
Subaddress 0x9C, SD Scale LSB Register = 0x2A
Subaddress 0x9D, SD Y Scale Register = 0xA6
Subaddress 0x9E, SD Cb Scale Register = 0xA6
Subaddress 0x9F, SD Cr Scale Register = 0xA6
If the ED/HD manual CSC matrix adjust feature is enabled and
another input standard (such as ED) is used, the scale values for

For NTSC with pedestal, the setup can vary from 0 IRE to 22.5 IRE.
For NTSC without pedestal and for PAL, the setup can vary
from −7.5 IRE to +15 IRE.
SD HUE ADJUST CONTROL
Subaddress 0xA0
When enabled, the SD hue adjust control register
(Subaddress 0xA0) is used to adjust the hue on the SD
composite and chroma outputs. This feature can be
enabled using Subaddress 0x87, Bit 2.
The SD brightness control register is an 8-bit register. The seven
LSBs of this 8-bit register are used to control the brightness
level, which can be a positive or negative value.
Subaddress 0xA0 contains the bits required to vary the hue of
the video data, that is, the variance in phase of the subcarrier
during active video with respect to the phase of the subcarrier
during the color burst. The ADV7340/ADV7341 provide a
range of ±22.5° in increments of 0.17578125°. For normal
operation (zero adjustment), this register is set to 0x80. Values
0xFF and 0x00 represent the upper and lower limits,
respectively, of the attainable adjustment in NTSC mode. Values
0xFF and 0x01 represent the upper and lower limits,
respectively, of the attainable adjustment in PAL mode.
For example, to add +20 IRE brightness level to an NTSC signal
with pedestal, write 0x28 to Subaddress 0xA1.
0 × (SD Brightness Value) =
0 × (IRE Value × 2.015631) =
0 × (20 × 2.015631) = 0 × (40.31262) ≈ 0x28
To add –7 IRE brightness level to a PAL signal, write 0x72 to
Subaddress 0xA1.
0 × (SD Brightness Value) =
0 × (IRE Value × 2.075631) =
The hue adjust value is calculated using the following equation:
0 × (7 × 2.015631) = 0x(14.109417) ≈ 0001110b
Hue Adjust (°) = 0.17578125° (HCRd − 128)
0001110b into twos complement = 1110010b = 0x72
where HCRd is the hue adjust control register (decimal)

SD INPUT STANDARD AUTO DETECTION
Subaddress 0x87, Bit 5
where the sum is rounded to the nearest integer.
The ADV7340/ADV7341 include an SD input standard autodetect feature. This SD feature can be enabled by setting
Subaddress 0x87, Bit 5 to 1.
SD BRIGHTNESS DETECT
Subaddress 0xBA
The ADV7340/ADV7341 allow monitoring of the brightness
level of the incoming video data. The SD brightness detect
register (Subaddress 0xBA) is a read-only register.
SD BRIGHTNESS CONTROL
Subaddress 0xA1, Bits[6:0]
When this feature is enabled, the SD brightness/WSS control
register (Subaddress 0xA1) is used to control brightness by
adding a programmable setup level onto the scaled Y data. This
feature can be enabled using Subaddress 0x87, Bit 3.
When enabled, the ADV7340/ADV7341 can automatically
identify an NTSC or PAL B/D/G/H/I input stream. The
ADV7340/ADV7341 automatically update the subcarrier
frequency registers with the appropriate value for the identified
standard. The ADV7340/ADV7341 are also configured to
correctly encode the identified standard.
The SD standard bits (Subaddress 0x80, Bits[1:0]) and the
subcarrier frequency registers are not updated to reflect the
identified standard. All registers retain their default or userdefined values.

DOUBLE BUFFERING
Subaddress 0x33, Bit 7 for ED/HD,
Subaddress 0x88, Bit 2 for SD
Double-buffered registers are updated once per field. Double
buffering improves overall performance because modifications
to register settings are not made during active video, but take
effect prior to the start of the active video on the next field.
Double buffering can be activated on the following ED/HD
registers using Subaddress 0x33, Bit 7: ED/HD Gamma A and
Gamma B curves, and ED/HD CGMS registers.
Double buffering can be activated on the following SD registers
using Subaddress 0x88, Bit 2: SD Gamma A and Gamma B
curves, SD Y scale, SD Cr scale, SD Cb scale, SD brightness, SD
closed captioning, and SD Macrovision Bits[5:0] (Subaddress
0xE0, Bits[5:0]).
PROGRAMMABLE DAC GAIN CONTROL
Subaddress 0x0A to Subaddress 0x0B
It is possible to adjust the DAC output signal gain up or down
from its absolute level. This is illustrated in Figure 69.
DAC 4 to DAC 6 are controlled by Register 0x0A.
DAC 1 to DAC 3 are controlled by Register 0x0B.

DAC is 4.33 mA, the DAC gain control feature can change this
output current from 4.008 mA (−7.5%) to 4.658 mA (+7.5%).
The reset value of the control registers is 0x00, that is, nominal

Gamma correction is available for SD and ED/HD video. For
both variations, there are 20, 8-bit registers. They are used to
program the Gamma Correction Curve A and Gamma
Correction Curve B.
ED/HD gamma correction is enabled using Subaddress 0x35,
Bit 5. ED/HD Gamma Correction Curve A is programmed at
Subaddress 0x44 to Subaddress 0x4D, and ED/HD Gamma
Correction Curve B is programmed at Subaddress 0x4E to
Subaddress 0x57.
Rev. 0 | Page 57 of 88
ADV7340/ADV7341
SD gamma correction is enabled using Subaddress 0x88, Bit 6.
SD Gamma Correction Curve A is programmed at Subaddress
0xA6 to Subaddress 0xAF, and SD Gamma Correction Curve B
is programmed at Subaddress 0xB0 to Subaddress 0xB9.
Gamma correction is performed on the luma data only. The
user can choose one of two correction curves, Curve A or
Curve B. Only one of these curves can be used at a time. For
ED/HD gamma correction, curve selection is controlled using
Subaddress 0x35, Bit 4. For SD gamma correction, curve
selection is controlled using Subaddress 0x88, Bit 7.
The shape of the gamma correction curve is controlled by
defining the curve response at 10 different locations along the
curve. By altering the response at these locations, the shape of
the gamma correction curve can be modified. Between these
points, linear interpolation is used to generate intermediate
values. Considering the curve has a total length of 256 points,
the 10 programmable locations are at points 24, 32, 48, 64, 80,
96, 128, 160, 192, and 224. Locations 0, 16, 240, and 255 are
fixed and cannot be changed.
To program the gamma correction registers, calculate the
10 programmable curve values using the following formula:
⎛ n − 16 ⎞ γ
⎞
γ n = ⎜⎜ ⎛⎜
⎟ × (240 − 16) ⎟⎟ + 16
⎝ ⎝ 240 − 16 ⎠
⎠
where:
γn is the value to be written into the gamma correction register
for point n on the gamma correction curve.
n = 24, 32, 48, 64, 80, 96, 128, 160, 192, or 224.
γ is the gamma correction factor.
For example, setting γ = 0.5 for all programmable curve data
points results in the following yn values:
y24 = [(8/224)0.5 × 224] + 16 = 58
y32 = [(16/224)0.5 × 224] + 16 = 76
y48 = [(32/224)0.5 × 224] + 16 = 101
y64 = [(48/224)0.5 × 224] + 16 = 120
y80 = [(64/224)0.5 × 224] + 16 = 136
y96 = [(80/224)0.5 × 224] + 16 = 150
From curve locations 16 to 240, the values at the programmable
locations and, therefore, the response of the gamma correction
curve should be calculated to produce the following result:
y128 = [(112/224)0.5 × 224] + 16 = 174
y160 = [(144/224)0.5 × 224] + 16 = 195
xDESIRED = (xINPUT)γ
y192 = [(176/224)0.5 × 224] + 16 = 214
where:
xDESIRED is the desired gamma corrected output.
xINPUT is the linear input signal.
γ is the gamma correction factor.
y224 = [(208/224)0.5 × 224] + 16 = 232
where the sum of each equation is rounded to the nearest integer.
The gamma curves in Figure 70 and Figure 71 are examples only;
any user-defined curve in the range from 16 to 240 is acceptable.

ADV7340/ADV7341
There are three filter modes available on the ADV7340/ADV7341:
a sharpness filter mode and two adaptive filter modes.
ED/HD Sharpness Filter Mode
To enhance or attenuate the Y signal in the frequency ranges
shown in Figure 72, the ED/HD sharpness filter must be
enabled (Subaddress 0x31, Bit 7) and the ED/HD adaptive filter
must be disabled (Subaddress 0x35, Bit 7).
To select one of the 256 individual responses, the corresponding
gain values, which range from –8 to +7 for each filter, must be
programmed into the ED/HD sharpness filter gain register at
Subaddress 0x40.
The edges can then be attenuated with the settings in the
ED/HD Adaptive Filter Gain 1, 2, and 3 registers (Subaddress
0x58, Subaddress 0x59, and Subaddress 0x5A, respectively), and
the ED/HD sharpness filter gain register (Subaddress 0x40).
There are two adaptive filter modes available. The mode
is selected using the ED/HD adaptive filter mode control
(Subaddress 0x35, Bit 6):
•
Mode A is used when the ED/HD adaptive filter mode
control is set to 0. In this case, Filter B (LPF) is used in the
adaptive filter block. In addition, only the programmed
values for Gain B in the ED/HD sharpness filter gain
register and ED/HD Adaptive Filter Gain 1, 2, and 3
registers are applied when needed. The Gain A values are
fixed and cannot be changed.
•
Mode B is used when ED/HD adaptive filter mode control
is set to 1. In this mode, a cascade of Filter A and Filter B is
used. Both settings for Gain A and Gain B in the ED/HD
sharpness filter gain register and ED/HD Adaptive Filter
Gain 1, 2, and 3 registers become active when needed.
ED/HD Adaptive Filter Mode
The ED/HD Adaptive Filter Threshold A, B, and C registers, the
ED/HD Adaptive Filter Gain 1, 2, and 3 registers, and the
ED/HD sharpness filter gain register are used in adaptive filter
mode. To activate the adaptive filter control, the ED/HD
sharpness filter and the ED/HD adaptive filter must be enabled
(Subaddress 0x31, Bit 7, and Subaddress 0x35, Bit 7, respectively).

In DNR mode, if the absolute value of the filter output is smaller
than the threshold, it is assumed to be noise. A programmable
amount (coring gain border, coring gain data) of this noise
signal is subtracted from the original signal. In DNR sharpness
mode, if the absolute value of the filter output is less than the
programmed threshold, it is assumed to be noise. Otherwise, if
the level exceeds the threshold, now identified as a valid signal,
a fraction of the signal (coring gain border, coring gain data) is
added to the original signal to boost high frequency components
and sharpen the video image.
In MPEG systems, it is common to process the video information
in blocks of 8 pixels × 8 pixels for MPEG2 systems, or 16 pixels ×
16 pixels for MPEG1 systems (block size control). DNR can be
applied to the resulting block transition areas that are known to
contain noise. Generally, the block transition area contains two
pixels. It is possible to define this area to contain four pixels
(border area).
It is also possible to compensate for variable block positioning
or differences in YCrCb pixel timing with the use of the DNR
block offset.
The digital noise reduction registers are three 8-bit registers.
They are used to control the DNR processing.

Coring Gain Border—Subaddress 0xA3, Bits[3:0]
These four bits are assigned to the gain factor applied to border

increments of 1/8. This factor is applied to the DNR filter
output that lies below the set threshold range. The result is then
subtracted from the original signal.
In DNR sharpness mode, the range of gain values is 0 to 0.5 in
increments of 1/16. This factor is applied to the DNR filter
output that lies above the threshold range. The result is added to
the original signal.
Coring Gain Data—Subaddress 0xA3, Bits[7:4]
These four bits are assigned to the gain factor applied to the luma

to the DNR filter output that lies below the set threshold range.
The result is then subtracted from the original signal.

DNR Threshold—Subaddress 0xA4, Bits[5:0]
These six bits are used to define the threshold value in the range
of 0 to 63. The range is an absolute value.
Border Area—Subaddress 0xA4, Bit 6
When this bit is set to Logic 1, the block transition area can be
defined to consist of four pixels. If this bit is set to Logic 0, the
border transition area consists of two pixels, where one pixel
refers to two clock cycles at 27 MHz.

DATA
DNR works on the principle of defining low amplitude, high
frequency signals as probable noise and subtracting this noise
from the original signal.
In DNR mode, it is possible to subtract a fraction of the signal
that lies below the set threshold, assumed to be noise, from the
original signal. The threshold is set in DNR Register 1.
When DNR sharpness mode is enabled, it is possible to add a
fraction of the signal that lies above the set threshold to the
original signal, because this data is assumed to be valid data and
not noise. The overall effect is that the signal is boosted (similar
to using the extended SSAF filter).
DNR Block Offset Control—Subaddress 0xA5, Bits[7:4]
Four bits are assigned to this control, which allows a shift of the
data block of 15 pixels maximum. Consider the coring gain
positions fixed. The block offset shifts the data in steps of one
pixel such that the border coring gain factors can be applied at the
same position regardless of variations in input timing of the data.

Block Size Control—Subaddress 0xA4, Bit 7
This bit is used to select the size of the data blocks to be processed.
Setting the block size control function to Logic 1 defines a 16 pixel
× 16 pixel data block, and Logic 0 defines an 8 pixel × 8 pixel
data block, where one pixel refers to two clock cycles at 27 MHz.
DNR Input Select Control—Subaddress 0xA5, Bits[2:0]
Three bits are assigned to select the filter, which is applied to the
incoming Y data. The signal that lies in the pass band of the
selected filter is the signal that is DNR processed. Figure 80
shows the filter responses selectable with this control.
When the active video edge control feature is enabled
(Subaddress 0x82, Bit 7 = 1), the first three pixels and the last
three pixels of the active video on the luma channel are scaled
so that maximum transitions on these pixels are not possible.
At the start of active video, the first three pixels are multiplied
by 1/8, 1/2, and 7/8, respectively. Approaching the end of active
video, the last three pixels are multiplied by 7/8, 1/2, and 1/8,
respectively. All other active video pixels pass through
unprocessed.

ADV7340/ADV7341
LOW POWER MODE
Subaddress 0x0D, Bits[2:0]
For power sensitive applications, the ADV7340/ADV7341
support an Analog Devices, Inc. proprietary low power mode of
operation on DAC 1, DAC 2, and DAC 3. To utilize this low
power mode, these DACs must be operating in full-drive mode
(RSET = 510 Ω, RL = 37.5 Ω). Low power mode is not available in
low drive mode (RSET = 4.12 kΩ, RL = 300 Ω). Low power mode
can be independently enabled or disabled on DAC 1, DAC 2, and
DAC 3 using Subaddress 0x0D, Bits[2:0]. Low power mode is
disabled by default on each DAC.
In low power mode, DAC current consumption is content
dependent. On a typical video stream, it can be reduced by as
much as 40%. For applications requiring the highest possible video
performance, low power mode should be disabled.
With this feature enabled, the cable detection circuitry monitors
DAC 1 and/or DAC 2 once per frame. If they are unconnected,
some or all of the DACs automatically power down. Which
DAC or DACs are powered down depends on the selected
output configuration.
For CVBS/YC output configurations, if DAC 1 is unconnected,
only DAC 1 powers down. If DAC 2 is unconnected, DAC 2 and
DAC 3 power down.
For YPrPb and RGB output configurations, if DAC 1 is
unconnected, all three DACs power down. DAC 2 is not
monitored for YPrPb and RGB output configurations.
CABLE DETECTION
Once per frame, DAC 1 and/or DAC 2 are monitored. If a cable
is detected, the appropriate DAC or DACs remain powered up
for the duration of the frame. If no cable is detected, the
appropriate DAC or DACs power down until the next frame
when the process is repeated.
Subaddress 0x10
PIXEL AND CONTROL PORT READBACK
The ADV7340/ADV7341 include an Analog Devices, Inc.
proprietary cable detection feature.
Subaddress 0x12 to Subaddress 0x16
The cable detection feature is available on DAC 1 and DAC 2,
while operating in full-drive mode (RSET1 = 510 Ω, RL1 = 37.5 Ω,
assuming a connected cable). The feature is not available in low
drive mode (RSET = 4.12 kΩ, RL = 300 Ω). For a DAC to be
monitored, the DAC must be powered up in Subaddress 0x00.
The cable detection feature can be used with all SD, ED, and
HD video standards. It is available for all output configurations,
that is, CVBS, YC, YPrPb, and RGB output configurations.
The ADV7340/ADV7341 support the readback of most digital
inputs via the I2C/SPI MPU port. This feature is useful for
board-level connectivity testing with upstream devices.
The pixel port (S[9:0], Y[9:0], and C[9:0]), the control port
(S_HSYNC, S_VSYNC, P_HSYNC, P_VSYNC and P_BLANK),
and the SFL/MISO pin are available for readback via the MPU
port. The readback registers are located at Subaddress 0x12 to
Subaddress 0x16.
When using this feature, a clock signal should be applied to
the CLKIN_A pin in order to register the levels applied to the
input pins.
For CVBS/YC output configurations, both DAC 1 and DAC 2
are monitored, that is, the CVBS and YC luma outputs are
monitored. For YPrPb and RGB output configurations, only
DAC 1 is monitored, that is, the luma or green output is
monitored.
RESET MECHANISM
Once per frame, the ADV7340/ADV7341 monitor DAC 1
and/or DAC 2, updating Subaddress 0x10, Bit 0 and Bit 1,
respectively. If a cable is detected on one of the DACs, the
relevant bit is set to 0. If not, the bit is set to 1.
The ADV7340/ADV7341 have a software reset accessible via
the I2C/SPI MPU port. A software reset is activated by writing
a 1 to Subaddress 0x17, Bit 1. This resets all registers to their
default values. This bit is self-clearing, that is, after a 1 has been
written to the bit, the bit automatically returns to 0.
DAC AUTO POWER-DOWN
Subaddress 0x10, Bit 4
For power sensitive applications, a DAC auto power-down feature
can be enabled using Subaddress 0x10, Bit 4. This feature is only
available when the cable detection feature is enabled.
Subaddress 0x17, Bit 1
When operating in SPI mode, a software reset does not cause
the device to revert to I2C mode. For this to occur, the
ADV7340/ADV7341 need to be powered down.
The ADV7340/ADV7341 include a power-on reset (POR)
circuit to ensure correct operation after power-up.

ADV7340/ADV7341
PRINTED CIRCUIT BOARD LAYOUT AND DESIGN
DAC CONFIGURATIONS
The ADV7340/ADV7341 contain six DACs. All six DACs can
be configured to operate in low drive mode. Low drive mode is
defined as 4.33 mA full-scale current into a 300 Ω load, RL.
DAC 1, DAC 2, and DAC 3 can also be configured to operate in
full-drive mode. Full-drive mode is defined as 34.7 mA fullscale current into a 37.5 Ω load, RL. Full-drive is the recommended
mode of operation for DAC 1, DAC 2, and DAC 3.
The ADV7340/ADV7341 contain two RSET pins. A resistor
connected between the RSET1 pin and AGND is used to control
the full-scale output current and, therefore, the DAC output
voltage levels of DAC 1, DAC 2, and DAC 3. For low drive
operation, RSET1 must have a value of 4.12 kΩ, and RL must have a
value of 300 Ω. For full-drive operation, RSET1 must have a value
of 510 Ω, and RL must have a value of 37.5 Ω.
A resistor connected between the RSET2 pin and AGND is used
to control the full-scale output current and, therefore, the DAC
output voltage levels of DAC 4, DAC 5, and DAC 6. RSET2 must
have a value of 4.12 kΩ, and RL must have a value of 300 Ω (that
is, low drive operation only).
For applications requiring an output buffer and reconstruction
filter, the ADA4430-1, ADA4411-3, and ADA4410-6 integrated
video filter buffers should be considered.

An optional reconstruction (anti-imaging) low-pass filter (LPF)
may be required on the ADV7340/ADV7341 DAC outputs if the
part is connected to a device that requires this filtering.
The filter specifications vary with the application. The use of
16× (SD), 8× (ED), or 4× (HD) oversampling can remove the
requirement for a reconstruction filter altogether.

The ADV7340/ADV7341 contain an on-chip voltage reference
that can be used as a board-level voltage reference via the VREF
pin. Alternatively, the ADV7340/ADV7341 can be used with an
external voltage reference by connecting the reference source to
the VREF pin. For optimal performance, an external voltage
reference such as the AD1580 should be used with the
ADV7340/ADV7341. If an external voltage reference is not
used, a 0.1 μF capacitor should be connected from the VREF pin
to VAA.

The termination resistors on the DAC output traces should be
placed as close as possible to and on the same side of the PCB as
the ADV7340/ADV7341. The termination resistors should
overlay the PCB ground plane.
It is recommended that a separate regulated supply be provided
for each power domain (VAA, VDD, VDD_IO, and PVDD). For
optimal performance, linear regulators rather than switch mode
regulators should be used. If switch mode regulators must be
used, care must be taken with regard to the quality of the output
voltage in terms of ripple and noise. This is particularly true for
the VAA and PVDD power domains. Each power supply should be
individually connected to the system power supply at a single
point through a suitable filtering device, such as a ferrite bead.
Rev. 0 | Page 67 of 88
ADV7340/ADV7341
Power Supply Decoupling
It is recommended that each power supply pin be decoupled
with 10 nF and 0.1 μF ceramic capacitors. The VAA, PVDD,
VDD_IO, and both VDD pins should be individually decoupled to
ground. The decoupling capacitors should be placed as close as
possible to the ADV7340/ADV7341 with the capacitor leads
kept as short as possible to minimize lead inductance.
A 1 μF tantalum capacitor is recommended across the VAA
supply in addition to the 10 nF and 0.1 μF ceramic capacitors.
Power Supply Sequencing
The ADV7340/ADV7341 are robust to all power supply
sequencing combinations. Any particular sequence can be used.
Digital Signal Interconnect
The digital signal traces should be isolated as much as possible
from the analog outputs and other analog circuitry. Digital
signal traces should not overlay the VAA or PVDD power planes.
Due to the high clock rates used, avoid long clock traces to the
ADV7340/ADV7341 to minimize noise pickup.
Any pull-up termination resistors for the digital inputs should
be connected to the VDD power supply.
Any unused digital inputs should be tied to ground.
Analog Signal Interconnect
DAC output traces should be treated as transmission lines with
appropriate measures taken to ensure optimal performance (for
example, impedance matched traces). The DAC output traces
should be kept as short as possible. The termination resistors on
the DAC output traces should be placed as close as possible to
and on the same side of the PCB as the ADV7340/ADV7341.
To avoid crosstalk between the DAC outputs, it is
recommended that as much space as possible be left between
the traces connected to the DAC output pins. Adding ground
traces between the DAC output traces is also recommended.

APPENDIX 1—COPY GENERATION MANAGEMENT SYSTEM
SD CGMS
Subaddress 0x99 to Subaddress 0x9B
The ADV7340/ADV7341 support copy generation management
system (CGMS) conforming to the EIAJ CPR-1204 and ARIB
TR-B15 standards. CGMS data is transmitted on Line 20 of the
odd fields and Line 283 of even fields. Subaddress 0x99,
Bits[6:5] control whether CGMS data is output on odd or even
fields or both.
SD CGMS data can only be transmitted when the ADV7340/
ADV7341 are configured in NTSC mode. The CGMS data is 20
bits long. The CGMS data is preceded by a reference pulse of
the same amplitude and duration as a CGMS bit (see Figure 91).
When HD CGMS is enabled (Subaddress 0x32, Bit 6 = 1), 720p
CGMS data is applied to Line 24 of the luminance vertical
blanking interval.
When HD CGMS is enabled (Subaddress 0x32, Bit 6 = 1), 1080i
CGMS data is applied to Line 19 and Line 582 of the luminance
vertical blanking interval.
The HD CGMS data registers are at Subaddress 0x41,
Subaddress 0x42, and Subaddress 0x43.
The ADV7340/ADV7341 also support CGMS Type B packets in
HD mode (720p and 1080i) in accordance with CEA-805-A.
ED CGMS
When HD CGMS Type B is enabled (Subaddress 0x5E, Bit 0 =
1), 720p CGMS data is applied to Line 23 of the luminance
vertical blanking interval.
Subaddress 0x41 to Subaddress 0x43
Subaddress 0x5E to Subaddress 0x6E
525p
When HD CGMS Type B is enabled (Subaddress 0x5E, Bit 0 =
1), 1080i CGMS data is applied to Line 18 and Line 581 of the
luminance vertical blanking interval.
The ADV7340/ADV7341 support copy generation management
system (CGMS) in 525p mode in accordance with EIAJ CPR1204-1.
The HD CGMS Type B data registers are at Subaddress 0x5E to
Subaddress 0x6E.
When ED CGMS is enabled (Subaddress 0x32, Bit 6 = 1), 525p
CGMS data is inserted on Line 41. The 525p CGMS data
registers are at Subaddress 0x41, Subaddress 0x42, and
Subaddress 0x43.
The ADV7340/ADV7341 also support CGMS Type B packets in
525p mode in accordance with CEA-805-A.
When ED CGMS Type B is enabled (Subaddress 0x5E, Bit 0 =
1), 525p CGMS Type B data is inserted on Line 40. The 525p
CGMS Type B data registers are at Subaddress 0x5E to
Subaddress 0x6E.
625p
The ADV7340/ADV7341 support copy generation management
system (CGMS) in 625p mode in accordance with IEC62375
(2004).
When ED CGMS is enabled (Subaddress 0x32, Bit 6 = 1), 625p
CGMS data is inserted on Line 43. The 625p CGMS data
registers are at Subaddress 0x42 and Subaddress 0x43.
HD CGMS
Subaddress 0x41 to Subaddress 0x43
Subaddress 0x5E to Subaddress 0x6E
The ADV7340/ADV7341 support copy generation management
system (CGMS) in HD mode (720p and 1080i) in accordance
with EIAJ CPR-1204-2.
CGMS CRC FUNCTIONALITY
If SD CGMS CRC (Subaddress 0x99, Bit 4) or ED/HD CGMS
CRC (Subaddress 0x32, Bit 7) is enabled, the upper six CGMS
data bits, C19 to C14, which comprise the 6-bit CRC check
sequence, are automatically calculated on the
ADV7340/ADV7341. This calculation is based on the lower 14
bits (C13 to C0) of the data in the CGMS data registers and the
result is output with the remaining 14 bits to form the complete
20 bits of the CGMS data. The calculation of the CRC sequence
is based on the polynomial x6 + x + 1 with a preset value of 111111.
If SD CGMS CRC or ED/HD CGMS CRC are disabled, all
20 bits (C19 to C0) are output directly from the CGMS registers
(CRC must be calculated by the user manually).
If ED/HD CGMS Type B CRC (Subaddress 0x5E, Bit 1) is
enabled, the upper six CGMS Type B data bits (P122 to P127)
that comprise the 6-bit CRC check sequence are automatically
calculated on the ADV7340/ADV7341. This calculation is
based on the lower 128 bits (H0 to H5 and P0 to P121) of the
data in the CGMS Type B data registers. The result is output
with the remaining 128 bits to form the complete 134 bits of the
CGMS Type B data. The calculation of the CRC sequence is
based on the polynomial x6 + x + 1 with a preset value of
111111.
If ED/HD CGMS Type B CRC is disabled, all 134 bits (H0 to H5
and P0 to P127) are output directly from the CGMS Type B
registers (CRC must be calculated by the user manually).

APPENDIX 2—SD WIDE SCREEN SIGNALING
The WSS data is preceded by a run-in sequence and a start code
(see Figure 98). If SD WSS (Subaddress 0x99, Bit 7) is set to
Logic 1, it enables the WSS data to be transmitted on Line 23.
The latter portion of Line 23 (42.5 sec from the falling edge of
HSYNC) is available for the insertion of video. It is possible to
blank the WSS portion of Line 23 with Subaddress 0xA1, Bit 7.
Subaddress 0x99, Subaddress 0x9A, Subaddress 0x9B
The ADV7340/ADV7341 support wide screen signaling (WSS)
conforming to the ETSI 300 294 standard. WSS data is
transmitted on Line 23. WSS data can be transmitted only when
the device is configured in PAL mode. The WSS data is 14 bits
long. The function of each of these bits is shown in Table 55.

ADV7340/ADV7341
APPENDIX 3—SD CLOSED CAPTIONING
The ADV7340/ADV7341 automatically generate all clock runin signals and timing that support closed captioning on Line 21
and Line 284. All pixels inputs are ignored on Line 21 and Line
284 if closed captioning is enabled.
Subaddress 0x91 to Subaddress 0x94
The ADV7340/ADV7341 support closed captioning conforming
to the standard television synchronizing waveform for color
transmission. Closed captioning is transmitted during the
blanked active line time of Line 21 of the odd fields and
Line 284 of the even fields.
The FCC Code of Federal Regulations (CFR) 47 Section 15.119
and EIA-608 describe the closed captioning information for
Line 21 and Line 284.
Closed captioning consists of a 7-cycle sinusoidal burst that is
frequency- and phase-locked to the caption data. After the clock
run-in signal, the blanking level is held for two data bits and is
followed by the Logic 1 start bit. Sixteen bits of data follow the
start bit. These consist of two 8-bit bytes, seven data bits, and one
odd parity bit. The data for these bytes is stored in the SD closed
captioning registers (Subaddress 0x93 to Subaddress 0x94).
The ADV7340/ADV7341 use a single buffering method. This
means that the closed captioning buffer is only 1-byte deep.
Therefore, there is no frame delay in outputting the closed
captioning data, unlike other 2-byte deep buffering systems.
The data must be loaded one line before it is output on Line 21
and Line 284. A typical implementation of this method is to use
VSYNC to interrupt a microprocessor, which in turn loads the
new data (2 bytes) in every field. If no new data is required for
transmission, 0s must be inserted in both data registers; this is
called nulling. It is also important to load control codes, all of
which are double bytes, on Line 21. Otherwise, a TV does not
recognize them. If there is a message such as “Hello World”
that has an odd number of characters, it is important to add a
blank character at the end to make sure that the end-of-caption,
2-byte control code lands in the same field.
The ADV7340/ADV7341 also support the extended closed
captioning operation, which is active during even fields and
encoded on Scan Line 284. The data for this operation is stored
in the SD closed captioning registers (Subaddress 0x91 to
Subaddress 0x92).

APPENDIX 4—INTERNAL TEST PATTERN GENERATION
SD TEST PATTERNS
The ADV7340/ADV7341 are able to generate SD color bar and
black bar test patterns.
The register settings in Table 56 are used to generate an SD
NTSC 75% color bar test pattern. CVBS output is available on
DAC 4, S-Video (Y/C) output is on DAC 5 and DAC 6, and
YPrPb output is on DAC 1 to DAC 3. Upon power-up, the
subcarrier frequency registers default to the appropriate values
for NTSC. All other registers are set as normal/default.

0x82
0x84
To generate an SD NTSC black bar test pattern, the same
settings shown in Table 56 should be used with an additional
write of 0x24 to Subaddress 0x02.
For PAL output of either test pattern, the same settings are used,
except that Subaddress 0x80 is programmed to 0x11 and the
subcarrier frequency registers are programmed as shown in
Table 57.

To generate an ED 525p flat field test pattern, the same settings
shown in Table 58 should be used, except that 0x0D should be
written to Subaddress 0x31.
The Y, Cr, and Cb levels for the hatch and flat field test patterns
can be controlled using Subaddress 0x36, Subaddress 0x37, and
Subaddress 0x38, respectively.
For ED/HD standards other than 525p, the same settings as
shown in Table 58 (and subsequent comments) are used except
that Subaddress 0x30, Bits[7:3] are updated as appropriate.

The ADV7340/ADV7341are controlled by the SAV (start of active video) and EAV (end of active video) time codes embedded in the
pixel data. All timing information is transmitted using a 4-byte synchronization pattern. A synchronization pattern is sent immediately
before and after each line during active picture and retrace. If the S_VSYNC and S_HSYNC pins are not used, they should be tied high
during this mode.

Mode 1—Master Option (Subaddress 0x8A = X X X X X 0 1 1)
In this mode, the ADV7340/ADV7341 can generate horizontal sync and odd/even field signals. When HSYNC is low, a transition of the
field input indicates a new frame, that is, vertical retrace. The ADV7340/ADV7341 automatically blank all normally blank lines as per
CCIR-624. Pixel data is latched on the rising clock edge following the timing signal transitions. HSYNC and FIELD are output on the
