TABLE OF CONTENTS
Features .............................................................................................. 1
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 I
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.
Tabl e 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 above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device 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.

Devices such as a microprocessor can communicate with the
ADV7342/ADV7343 through a 2-wire serial (I
2
C-compatible)
bus. After power-up or reset, the MPU port is configured for
2
I
C 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 Ta b le 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.

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

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:
•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
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.
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 17 to Table 35 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.
