ADV7342/ADV7343
GENERAL DESCRIPTION
The ADV7342/ADV7343 are high speed, digital-to-analog
video encoders in a 64-lead LQFP package. Six high speed,
3.3 V, 11-bit video DACs provide support for composite
(CVBS), S-Video (Y-C), and component (YPrPb/RGB) analog
outputs in standard definition (SD), enhanced definition (ED),
or high definition (HD) video formats.
The ADV7342/ADV7343 have a 24-bit pixel input port that can
be configured in a variety of ways. SD video formats are supported over an 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® communication
protocol.
In addition, simultaneous SD and ED/HD input and output are
supported. Full-drive DACs ensure that external output buffering
is not required, while 216 MHz (SD and ED) and 297 MHz
(HD) oversampling ensures that external output filtering is not
required.
Cable detection and DAC autopower-down features keep power
consumption to a minimum.
Table 1 lists the video standards directly supported by the
ADV7342/ADV7343.

Analog output short circuit to any power supply or common can be of an
indefinite duration.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
The ADV7342/ADV7343 are high performance integrated
circuits with an ESD rating of <1 kV, and they are ESD sensitive.
Proper precautions should be taken for handling and assembly.

Values are based on a JEDEC 4-layer test board.
The ADV7342/ADV7343 are RoHS-compliant, Pb-free products.
The lead finish is 100% pure Sn electroplate. The devices are
suitable for Pb-free applications up to 255°C (±5°C) IR reflow
(JEDEC STD-20).
They are backward compatible with conventional SnPb soldering
processes. The electroplated Sn coating can be soldered with
Sn/Pb solder paste at conventional reflow temperatures of
220°C to 235°C.

MPU PORT DESCRIPTION
Devices such as a microprocessor can communicate with the
ADV7342/ADV7343 through a 2-wire serial (I2C-compatible)
bus. After power-up or reset, the MPU port is configured for
I2C operation.
I2C OPERATION
The ADV7342/ADV7343 support a 2-wire serial (I2C-compatible)
microprocessor bus driving multiple peripherals. This port
operates in an open-drain configuration. Two wires, serial data
(SDA) and serial clock (SCL), carry information between any
device connected to the bus and the ADV7342/ADV7343. The
slave address of the device depends on the device (ADV7342 or
ADV7343), the operation (read or write), and the state of the
ALSB pin (0 or 1). See Table 16, Figure 47, and Figure 48. The
LSB sets either a read or a write operation. Logic 1 corresponds
to a read operation, and Logic 0 corresponds to a write
operation. A1 is controlled by setting the ALSB pin of the
ADV7342/ADV7343 to Logic 0 or Logic 1.

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 plus the R/W bit). The bits are
transferred from MSB down to LSB. The peripheral that
recognizes the transmitted address responds by pulling the data
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 ADV7342/ADV7343 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 ADV7342/ADV7343 do not issue an
acknowledge but return to the idle condition. If the user uses the
auto-increment method of addressing the encoder and exceeds
the highest subaddress, the following actions are taken:

Analog Devices, Inc., recommends tying up ALSB. If this is not
done, a power supply sequence (PSS) may be required. For more
information on the PSS, see the Power Supply Sequencing section.
The various devices on the bus use the following protocol. The
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 ADV7342/ADV7343, and the parts return to the idle
condition.
Figure 49 shows data transfer for a write sequence and the start
and stop conditions. Figure 50 shows bus write and read
sequences.

REGISTER MAP ACCESS
REGISTER PROGRAMMING
A microprocessor can read from or write to all registers of the
ADV7342/ADV7343 via the MPU port, except for registers that
are specified as read-only or write-only registers.
Table 17 to Table 35 describe the functionality of each register.
All registers can be read from as well as written to, unless
otherwise stated.
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.
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.

INPUT CONFIGURATION
16-Bit 4:2:2 YCrCb Mode
Subaddress 0x87, Bit 7 = 0; Subaddress 0x88, Bit 3 = 1
The ADV7342/ADV7343 support a number of different input
modes. The desired input mode is selected using Subaddress
0x01, Bits[6:4]. The ADV7342/ADV7343 default to standard
definition only (SD only) on power-up. Table 36 provides an
overview of all possible input configurations. Each input mode
is described in detail in the following sections.
In 16-bit 4:2:2 YCrCb input mode, the Y pixel data is input on
Pin S7 to Pin S0 (or Pin Y7 to Pin Y0, depending on Subaddress
0x01, Bit 7), with Pin S0/Y0 being the LSB.
STANDARD DEFINITION ONLY
Subaddress 0x01, Bits[6:4] = 000
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.
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.
8-Bit 4:2:2 YCrCb Mode
Subaddress 0x87, Bit 7 = 0; Subaddress 0x88, Bit 3 = 0
In 8-bit 4:2:2 YCrCb input mode, the interleaved pixel data is
input on Pin S7 to Pin S0 (or Pin Y7 to Pin Y0, depending on
Subaddress 0x01, Bit 7), with Pin S0/Y0 being the LSB. The
ITU-R BT.601/656 input standard is supported. Embedded
EAV/SAV timing codes are also supported.
The CrCb pixel data is input on Pin Y7 to Pin Y0 (or Pin C7 to
Pin C0, depending on Subaddress 0x01, Bit 7), with Pin Y0/C0
being the LSB. Embedded EAV/SAV timing codes are not
supported, so an external synchronization is needed in this mode.
24-Bit 4:4:4 RGB Mode
Subaddress 0x87, Bit 7 = 1
In 24-bit 4:4:4 RGB input mode, the red pixel data is input on
Pin S7 to Pin S0, the green pixel data is input on Pin Y7 to
Pin Y0, and the blue pixel data is input on Pin C7 to Pin C0.
The S0, Y0, and C0 pins are the respective bus LSBs.
Embedded EAV/SAV timing codes are not supported with SD
RGB mode. In addition, master timing mode is not supported
for SD RGB input mode; therefore, external synchronization
must be used.

DESIGN FEATURES
OUTPUT OVERSAMPLING
The ADV7342/ADV7343 include two on-chip phase-locked
loops (PLLs) that allow for oversampling of SD, ED, and HD
video data. Table 41 shows the various oversampling rates
supported in the ADV7342/ADV7343.
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.
External Sync Polarity
For SD and ED/HD modes, the ADV7342/ADV7343 parts
typically expect HS and VS to be low during their respective
blanking periods. However, when the CEA861 compliance bit is
enabled (0x39, Bit 5 for ED/HD modes and 0x86, Bit 3 for SD
modes), the part expects the HS or VS to be active low or high,
depending on the input format selected (0x30 Bits [7:3]).
If a polarity other than the default is needed for ED/HD modes,
0x3A Bits [2:0] can be used to invert PHSYNCB, PVSYNCB or
PBLANKB individually, regardless of whether CEA-861-B mode is
enabled. It is not possible to invert S_HSYNC or S_VSYNC.
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.

HD INTERLACE EXTERNAL P_HSYNC AND
P_VSYNC CONSIDERATIONS
ED/HD TIMING RESET
If the encoder revision code (Subaddress 0xBB, Bits[7:6]) = 01
or higher, the user should set Subaddress 0x02, Bit 1 to high to
ensure exactly correct timing in HD interlace modes when
using the P_HSYNCand P_VSYNC synchronization signals. If
this bit is set to low, the first active pixel on each line is masked
and the Pr and Pb outputs are swapped when using the YCrCb
4:2:2 input format. Setting Subaddress 0x02, Bit 1 to low causes
the encoder to behave in the same way as the first version of
silicon (that is, this setting is backward compatible).
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.
Subaddress 0x34, Bit 0
SD SUBCARRIER FREQUENCY LOCK
Subcarrier Frequency Lock (SFL) Mode
In this mode (Subaddress 0x84, Bits[2:1] = 11), the ADV7342/
ADV7343 can be used to lock to an external video source. The
SFL mode allows the ADV7342/ADV7343 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 59) 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.
If the encoder revision code (Subaddress 0xBB, Bits[7:6] = 00,
the setting of Subaddress 0x02, Bit1 has no effect. In this version
of the encoder, the first active pixel is masked and Pr and Pb
outputs are swapped when using the YCrCb 4:2:2 input format.
To avoid these limitations, use the newer version of silicon or a
different type of synchronization.
These considerations apply only to the HD interlace modes
with external P_HSYNCand P_VSYNC synchronization
(EAV/SAV mode is not affected and always has exactly correct
timing). There is no negative effect in setting Subaddress 0x02,
Bit 0 to high, and this bit can remain high for all the other video
standards.

Data Sheet
SD VCR FF/RW SYNC
For example, in NTSC mode
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 mode.
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.
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.
This control is available in all slave-timing modes except Slave
Mode 0.
VERTICAL BLANKING INTERVAL
The ADV7342/ADV7343 are able to accept input data that
contains VBI data (such as CGMS, WSS, and VITS) in SD, ED,
and HD modes.
If VBI is disabled (Subaddress 0x31, Bit 4 for ED/HD;
Subaddress 0x83, Bit 4 for SD), VBI data is not present at the
output and the entire VBI is blanked. These control bits are
valid in all master and slave timing 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.
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 is received by
the ADV7342/ADV7343. The SD input standard autodetection
feature must be disabled.
Typical FSC Values
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.
If CGMS is enabled and VBI is disabled, the CGMS data is,
nevertheless, available at the output.
SD SUBCARRIER FREQUENCY CONTROL
Subaddress 0x8C to Subaddress 0x8F
The ADV7342/ADV7343 are able to generate the color subcarrier
used in CVBS and S-Video (Y-C) outputs from the input pixel
clock. Four 8-bit registers are used to set up the subcarrier
frequency. The value of these registers is calculated using
Subcarrier Frequency Register =
× 2 32

The ADV7342/ADV7343 support an 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)
can be input into the ADV7342/ADV7343. The SD
noninterlaced mode can be enabled using Subaddress 0x88, Bit
1.
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 ADV7342/ADV7343 should be
configured for NTSC operation, and Subaddress 0x88, Bit 1
should be set to 1.
For 288p/50 Hz input, the ADV7342/ADV7343 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 ADV7342/ADV7343 support an SD square pixel mode
(Subaddress 0x82, Bit 4). For NTSC operation, an input clock of
24.5454 MHz is required. The active resolution is 640 × 480. For
PAL operation, an input clock of 29.5 MHz is required. The
active resolution is 768 × 576.
For CVBS and S-Video (Y-C) outputs, the SD subcarrier
frequency registers must be updated to reflect the input clock
frequency used in SD square pixel mode. The SD input standard
autodetection feature must be disabled in SD square pixel
mode. In square pixel mode, the timing diagrams shown in
Figure 60 and Figure 61 apply.

Table 44. Internal Filter Specifications
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 38 and Figure 39.
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 in
frequency responses is shown in Figure 35 to Figure 37.
In addition to the chroma filters listed in Table 43, the ADV7342/
ADV7343 contain an SSAF filter that is 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 62). This filter can be controlled with Subaddress
0x82, Bit 0.

Subaddress 0x33, Bit 3
The ADV7342/ADV7343 include a filter designed to counter
the effect of sinc roll-off in DAC 1, DAC 2, and DAC 3 while
operating in ED/HD mode. This filter is enabled by default. It
can be disabled using Subaddress 0x33, Bit 3. The benefit of the
filter is illustrated in Figure 63 and Figure 64.

Three 8-bit registers at Subaddress 0x36 to Subaddress 0x38
are used to program the output color of the internal ED/HD
test pattern generator (Subaddress 0x31, Bit 2 = 1), whether it
be the lines of the crosshatch pattern or the uniform field test
pattern. They are not functional as color controls for external
pixel data input.
The values for the luma (Y) and the color difference (Cr and

SD Manual CSC Matrix Adjust Feature
The SD manual CSC matrix adjust feature provides custom
coefficient manipulation for RGB to YPbPr conversion (for
YPbPr to RGB conversion, this matrix adjustment is not
available).
Normally, there is no need to modify the SD matrix coefficients
because the CSC matrix automatically performs the color space
conversion based on the output color space selected (see Table 46).
Note that Bit 7 in Subaddress 0x87 must be set to enable RGB
input and, therefore, use the CSC manual adjustment.
Table 45 shows sample color values that can be programmed
into the color registers when the output standard selection is set
to EIA 770.2/EIA 770.3 (Subaddress 0x30, Bits[1:0] = 00).

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):
R = Y + 1.575Pr
G = Y − 0.468Pr − 0.187Pb
B = Y + 1.855Pb
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.
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.
If the ED/HD manual CSC matrix adjust feature is enabled and
another input standard (such as ED) is used, the scale values for
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 may use different scale values.
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 47). For this reason, the ED/HD
manual CSC matrix adjust feature is disabled by default.
For example, SMPTE 293M uses the following conversion:
If RGB output is selected, the ED/HD CSC matrix scalar uses
the following equations:
R = GY × Y + RV × Pr
The programmable CSC matrix is used for external ED/HD
pixel data and is not functional when internal test patterns are
enabled.
G = GY × Y − (GU × Pb) − (GV × Pr)
Programming the CSC Matrix
B = GY × Y + BU × Pb
If custom manipulation of the ED/HD CSC matrix coefficients
is required for a YCrCb-to-RGB color space conversion, use the
following procedure:
Note that subtractions are implemented in hardware.
If YPrPb output is selected, the following equations are used:
Y = GY × Y
Pr = RV × Pr
Pb = BU × Pb
where:
GY = Subaddress 0x05, Bits[7:0] and Subaddress 0x03, Bits[1:0].
GU = Subaddress 0x06, Bits[7:0] and Subaddress 0x04, Bits[7:6].
GV = Subaddress 0x07, Bits[7:0] and Subaddress 0x04, Bits[5:4].
BU = Subaddress 0x08, Bits[7:0] and Subaddress 0x04, Bits[3:2].
RV = Subaddress 0x09, Bits[7:0] and Subaddress 0x04, Bits[1:0].
R = Y + 1.402Pr
G = Y – 0.714Pr – 0.344Pb
B = Y + 1.773Pb

SD LUMA AND COLOR SCALE CONTROL
For example, to adjust the hue by +4°, write 0x97 to the hue
adjust control register.
Subaddress 0x9C to Subaddress 0x9F
When enabled, the SD luma and color scale control feature can
be used to scale the SD Y, Cb, and Cr output levels. This feature
can be enabled using Subaddress 0x87, Bit 0. This feature affects
all SD output signals, that is, CVBS, Y-C, YPrPb, and RGB.
When enabled, three 10-bit registers (SD Y Scale, SD Cb scale,
and SD Cr scale) control the scaling of the SD Y, Cb, and Cr
output levels. The SD Y scale register contains the scaling factor
used to scale the Y level from 0.0 to 1.5 times its initial level.
The SD Cb scale and SD Cr scale registers contain the scaling
factors to scale the Cb and Cr levels from 0.0 to 2.0 times their
initial levels, respectively.
The values to be written to these 10-bit registers are calculated
using the following equation:
Y, Cb, or Cr Scale Value = Scale Factor × 512
For example, if Scale Factor = 1.3
Y, Cb, or Cr Scale Value = 1.3 × 512 = 665.6
Y, Cb, or Cr Scale Value = 666 (rounded to the nearest integer)
Y, Cb, or Cr Scale Value = 1010 0110 10b

SD BRIGHTNESS DETECT
Subaddress 0xBA
The ADV7342/ADV7343 allow monitoring of the brightness
level of the incoming video data. This feature is used to monitor
the average brightness of the incoming Y signal on a field-byfield basis. The information is read from the I2C and, based on
this information, the color saturation, contrast, and brightness
controls can be adjusted (for example, to compensate for very
dark pictures).
The luma data is monitored in the active video area only. The
average brightness I2C register is updated on the falling edge of
every VSYNC signal. The SD brightness detect register (Subaddress 0xBA) is a read-only register.
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
It is recommended that the SD luma scale saturation feature
(Subaddress 0x87, Bit 1) be enabled when scaling the Y output
level to avoid excessive Y output levels.
SD BRIGHTNESS CONTROL
Subaddress 0xA1, Bits[6:0]
Subaddress 0xA0
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 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.
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.
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 ADV7342/ADV7343 provide a range
of ±22.5° in increments of 0.17578125°. For normal operation
(zero adjustment), this register is set to 0x80. Value 0xFF and
Value 0x00 represent the upper and lower limits, respectively, of the
attainable adjustment in NTSC mode. Value 0xFF and Value 0x01
represent the upper and lower limits, respectively, of the attainable
adjustment in PAL mode.
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.
SD HUE ADJUST CONTROL
For example, to add a +20 IRE brightness level to an NTSC
signal with pedestal, write 0x28 to Subaddress 0xA1.
The hue adjust value is calculated using the following equation:
Hue Adjust (°) = 0.17578125° (HCRd − 128)
where HCRd is the hue adjust control register (decimal).

frequency registers with the appropriate value for the identified
standard. The ADV7342/ADV7343 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

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: the 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: the 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]) registers.
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 66.
DAC 4 to DAC 6 are controlled by Register 0x0A.
DAC 1 to DAC 3 are controlled by Register 0x0B.

In Case B of Figure 66, the video output signal is reduced. The
absolute level of the sync tip and the blanking level decrease
with respect to the reference video output signal. The overall
gain of the signal is reduced from the reference signal.
The range of this feature is specified for ±7.5% of the nominal
output from the DACs. For example, if the output current of the
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
DAC current is output. Table 51 shows how the output current
of the DACs varies for a nominal 4.33 mA output current.

where γ is the gamma correction factor.
Gamma correction is available for SD and ED/HD video. For
both variations, there are twenty 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. E | Page 61 of 106
ADV7342/ADV7343
Data Sheet
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 that the curve has a total length of 256
points, the 10 programmable locations are at the following
points: 24, 32, 48, 64, 80, 96, 128, 160, 192, and 224. The
following locations are fixed and cannot be changed: 0, 16, 240,
and 255.
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
y128 = [(112/224)0.5 × 224] + 16 = 174
From the 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:
xDESIRED = (xINPUT)γ
y160 = [(144/224)0.5 × 224] + 16 = 195
y192 = [(176/224)0.5 × 224] + 16 = 214
y224 = [(208/224)0.5 × 224] + 16 = 232
where the sum of each equation is rounded to the nearest integer.
where:
xDESIRED is the desired gamma corrected output.
xINPUT is the linear input signal.
γ is the gamma correction factor.
The gamma curves in Figure 67 and Figure 68 are examples only;
any user-defined curve in the range from 16 to 240 is acceptable.

respectively). The recommended threshold range is 16 to 235,
although any value in the range of 0 to 255 can be used.
To enhance or attenuate the Y signal in the frequency ranges
shown in Figure 69, 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).
The edges can then be attenuated with the settings in the
ED/HD adaptive filter (Gain 1, Gain 2, and Gain 3) registers
(Subaddress 0x58, Subaddress 0x59, and Subaddress 0x5A,
respectively), and the ED/HD sharpness filter gain register
(Subaddress 0x40).
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.
There are two adaptive filter modes available. The mode
is selected using the ED/HD adaptive filter mode control
(Subaddress 0x35, Bit 6) as follows:

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, Gain 2, and
Gain 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, Gain 2, and Gain 3) registers become active when
needed.

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.

Digital noise reduction (DNR) is applied to the Y data only.
A filter block selects the high frequency, low amplitude components of the incoming signal (DNR input select). The absolute
value of the filter output is compared to a programmable
threshold value (DNR threshold control). There are two DNR
modes available: DNR mode and DNR sharpness mode.

Coring Gain Border—Subaddress 0xA3, Bits[3:0]
These four bits are assigned to the gain factor applied to border
areas. In DNR mode, the range of gain values is 0 to 1 in
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
data inside the MPEG pixel block. In DNR mode, the range of

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

This bit controls the DNR mode selected. Logic 0 selects DNR

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).

Four bits are assigned to this control, which allows a shift of the

positions fixed. The block offset shifts the data in steps of one

same position regardless of variations in input timing of the data.

This bit is used to select the size of the data blocks to be

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.
The ADV7342/ADV7343 are able to control fast rising and
falling signals at the start and end of active video in order to
minimize ringing.
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,

LOW POWER MODE
Subaddress 0x0D, Bits[2:0]
For power-sensitive applications, the ADV7342/ADV7343
support an Analog Devices proprietary low power mode of
operation on DAC 1, DAC 2, and DAC 3. To use this low power
mode, these DACs must be operating in full-drive mode (RSET1
= 510 Ω, RL = 37.5 Ω). Low power mode is not available in lowdrive 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.
CABLE DETECTION
Subaddress 0x10
The ADV7342/ADV7343 include an Analog Devices proprietary cable detection feature. 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 (RSET1 =
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.
Once per frame, the ADV7342/ADV7343 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.
DAC AUTOPOWER-DOWN
Subaddress 0x10, Bit 4
For power-sensitive applications, a DAC autopower-down
feature can be enabled using Subaddress 0x10, Bit 4. This feature
is available only when the cable detection feature is enabled.
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.
Once per frame, DAC 1 and/or DAC 2 is 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.
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

Data Sheet
SLEEP MODE
The ADV7342/ADV7343 include a power-on reset (POR)
circuit to ensure correct operation after power-up.
Subaddress 0x00, Bit 0
SD TELETEXT INSERTION
In sleep mode, most of the digital I/O pins of the ADV7342/
ADV7343 are disabled. For inputs, this means that the external
data is ignored, and internally the logic normally driven by a
given input is just tied low or high. This includes CLKINx.
Subaddress 0xC9 to Subaddress 0xCE
The ADV7342/ADV7343 support the insertion of teletext data,
using a 2-pin interface, when operating in PAL mode. Teletext
insertion is enabled using Subaddress 0xC9, Bit 0.
For digital output pins, this means that the pin goes into tristate
(high impedance) mode.
In accordance with the PAL WST teletext standard, teletext data
should be inserted into the ADV7342/ADV7343 at a rate of
6.9375 Mbps. The teletext data can be inserted on the
S_VSYNC, P_VSYNC, or C0 pin. The pin on which the teletext
data is inserted is selected using Subaddress 0xC9, Bits [3:2].
There are some exceptions to allow the user to continue to
communicate with the part via I2C: the ALSB, SDA, and SCL
pins are kept alive.
PIXEL AND CONTROL PORT READBACK
When teletext insertion is enabled, a teletext request signal is
output from the ADV7342/ADV7343 to indicate when teletext
data should be inserted. The teletext request signal is output on
the SFL pin. The position (relative to the teletext data) and
width of the request signal are configurable using Subaddress
0xCA. The request signal can operate in either a line or a bit
mode. The request signal mode is controlled using Subaddress
0xC9, Bit 1.
Subaddress 0x12 to Subaddress 0x14, Subaddress 0x16
The ADV7342/ADV7343 support the readback of most digital
inputs via the I2C MPU port. This feature is useful for board
level connectivity testing with upstream devices.
The pixel port (S[7:0], Y[7:0], and C[7:0]), the control port
(S_HSYNC, S_VSYNC, P_HSYNC, P_VSYNC, and P_BLANK),
and the SFL pin are available for readback via the MPU port.
The readback registers are located at Subaddress 0x12 to
Subaddress 0x14 and Subaddress 0x16.
To account for the noninteger relationship between the teletext
insertion rate (6.9375 Mbps) and the pixel clock (27 MHz), a
teletext insertion protocol is implemented in the ADV7342/
ADV7343. At a rate of 6.9375 Mbps, the time taken for the
insertion of 37 teletext bits equates to 144 pixel clock cycles (at
27 MHz). For every 37 teletext bits inserted into the ADV7342/
ADV7343, the 10th, 19th, 28th, and 37th bits are carried for three
pixel clock cycles, and the remainder are carried for four pixel
clock cycles (totaling 144 pixel clock cycles). The teletext
insertion protocol repeats every 37 teletext bits or 144 pixel
clock cycles until all 360 teletext bits are inserted.
When using this feature, apply a clock signal to the CLKIN_A
pin to register the levels applied to the input pins.
RESET MECHANISM
Subaddress 0x17, Bit 1
The ADV7342/ADV7343 have a software reset accessible via
the I2C 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.

UNUSED PINS
If the S_HSYNC, S_VSYNC, P_HSYNC, and P_VSYNC pins are
not used, they should be tied to VDD_IO through a pull-up resistor
(10 kΩ or 4.7 kΩ). Any other unused digital inputs should be tied
to ground. Unused digital output pins should be left floating. DAC
outputs can be either left floating or connected to GND. Disabling
these outputs is recommended.
DAC CONFIGURATIONS
The ADV7342/ADV7343 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.
An optional reconstruction (anti-imaging) low-pass filter (LPF)
may be required on the ADV7342/ADV7343 DAC outputs if
the ADV7342/ADV7343 are 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.
For applications requiring an output buffer and reconstruction
filter, the ADA4430-1, ADA4411-3, and ADA4410-6 integrated
video filter buffers should be considered.
Table 58. ADV7342/ADV7343 Output Rates
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.

SD Only
The ADV7342/ADV7343 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.
ED Only
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).

The ADV7342/ADV7343 contain an on-chip voltage reference
that can be used as a board-level voltage reference via the VREF
pin. Alternatively, the ADV7342/ADV7343 can be used with an
external voltage reference by connecting the reference source to
the VREF pin. For optimal performance, use an external voltage
reference such as the AD1580 with the ADV7342/ADV7343. If an
external voltage reference is not used, a 0.1 µF capacitor should
be connected from the VREF pin to VAA.

traces as short as possible.
The termination resistors on the DAC output traces should be

Rev. E | Page 73 of 106
ADV7342/ADV7343
Data Sheet
External filter and buffer components connected to the DAC
outputs should be placed as close as possible to the ADV7342/
ADV7343 to minimize the possibility of noise pickup from
neighboring circuitry and to minimize the effect of trace
capacitance on output bandwidth. This is particularly important
when operating in low-drive mode (RSETx = 4.12 kΩ, RL = 300 Ω).
Power Supplies
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.
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 ADV7342/ADV7343 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.
be established a minimum of 250 µs prior to the VDD power
supply being established. The VAA and PVDD power supplies can
be established at any time and in any order. Tying ALSB to
VDD_IO completely removes this PSS requirement.
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 plane.
Due to the high clock rates used, avoid long clock traces to the
ADV7342/ADV7343 to minimize noise pickup.
Any pull-up termination resistors for the digital inputs should
be connected to the VDD_IO 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 ADV7342/ADV7343.
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.
Power Supply Sequencing
If the ALSB pin is tied low, a power supply sequence is required
for proper operation of the part. The VDD_IO power supply must

COPY GENERATION MANAGEMENT SYSTEM
SD CGMS
Subaddress 0x99 to Subaddress 0x9B
The ADV7342/ADV7343 support a copy generation
management system (CGMS) conforming to the EIAJ CPR1204 and ARIB TR-B15 standards. CGMS data is transmitted
on Line 20 of 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 be transmitted only when the ADV7342/
ADV7343 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 90).
ED CGMS
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 ADV7342/ADV7343 also support CGMS Type B packets in
HD mode (720p and 1080i) in accordance with CEA-805-A.
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.
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.
Subaddress 0x41 to Subaddress 0x43;
Subaddress 0x5E to Subaddress 0x6E
525p Mode
The HD CGMS Type B data registers are at Subaddress 0x5E to
Subaddress 0x6E.
The ADV7342/ADV7343 support a copy generation management system (CGMS) in 525p mode in accordance with EIAJ
CPR-1204-1.
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
ADV7342/ADV7343. 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.
When ED CGMS is enabled (Subaddress 0x32, Bit 6 = 1), 525p
CGMS data is inserted on Line 41 and the 525p CGMS data
registers are at Subaddress 0x41, Subaddress 0x42, and Subaddress 0x43. The ADV7342/ADV7343 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 Mode
The ADV7342/ADV7343 support a 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 ADV7342/ADV7343 support a copy generation management
system (CGMS) in HD mode (720p and 1080i) in accordance
with EIAJ CPR-1204-2.
When HD CGMS is enabled (Subaddress 0x32, Bit 6 = 1), 720p
CGMS data is applied to Line 24 of the luminance vertical
blanking interval.
CGMS CRC FUNCTIONALITY
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 ADV7342/ADV7343. 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).

SD CLOSED CAPTIONING
and Line 284. All pixels inputs are ignored on Line 21 and on
Line 284 if closed captioning is enabled.
Subaddress 0x91 to Subaddress 0x94
The ADV7342/ADV7343 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 seven-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 ADV7342/ADV7343 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).
The ADV7342/ADV7343 automatically generate all clock runin signals and timing that support closed captioning on Line 21
10.5 ± 0.25µs
The ADV7342/ADV7343 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 (two 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 ADV7342/ADV7343 are able to internally generate SD
color bar and black bar test patterns. For this function, a
27 MHz clock signal must be applied to the CLKIN_A pin.
The ADV7342/ADV7343 are able to internally generate ED/HD
black bar and hatch test patterns. For ED test patterns, a 27 MHz
clock signal must be applied to the CLKIN_A pin. For HD test
patterns, a 74.25 MHz clock signal must be applied to the
CLKIN_A pin.
The register settings in Table 61 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. On power-up, the
subcarrier frequency registers default to the appropriate values
for NTSC. All other registers are set as normal/default.

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

To generate an ED 525p flat field test pattern, the settings
shown in Table 63 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 settings shown in
Table 63 (and subsequent comments) are used, except that
Subaddress 0x30, Bits[7:3] are updated as appropriate.

The ADV7342/ADV7343 are 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 to
VDD_IO during this mode.
