ADV7344 Data Sheet
TABLE OF CONTENTS
Features .............................................................................................. 1
The ADV7344 is a high speed, digital-to-analog video encoder
in a 64-pin LQFP package. Six high speed, NSV, 3.3 V, 14-bit
video DACs provide support for composite (CVBS), S-Video
(YC), and component (YPrPb/RGB) analog outputs in standard
definition (SD), enhanced definition (ED), or high definition
(HD) video formats.
The ADV7344 has a 30-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 space.
The ADV7344 also supports embedded EAV/SAV timing codes,
external video synchronization signals, and I
protocol.
In addition, simultaneous SD and ED/HD input and output is
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
ADV7344.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress

device reliability.
The ADV7344 is a high performance integrated circuit with an
ESD rating of <1 kV, and it is ESD sensitive. Proper precautions

The ADV7344 is an RoHS-compliant, Pb-free product. The lead
finish is 100% pure Sn electroplate. The device is suitable for Pbfree applications up to 255°C (±5°C) IR reflow (JEDEC STD-20).
It is 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
ADV7344 through a 2-wire serial l(I
power-up or reset, the MPU port is configured for I
2
C-compatible) bus. After
2
C operation.
I2C OPERATION
The ADV7344 supports 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 ADV7344. The slave
address of the ADV7344 depends on the operation (read or
write) and the state of the ALSB pin (0 or 1). See Ta b l e 16 and
Figure 47. 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
ADV7344 to Logic 0 or Logic 1.
Table 16. ADV7344 I

ADV7344 0 Write 0xD4

1 Write 0xD6
1 Read 0xD7
Analog Devices, Inc., strongly recommends tying ALSB to
V
. If this is not done, a power supply sequence (PSS) may be
DD_IO
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
W
the R/
bit).The bits are transferred from MSB down to LSB.
The peripheral that recognizes the transmitted address
2
C Slave Addresses

C Slave 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 ADV7344 acts 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 ADV7344 does
not issue an acknowledge but returns 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 ADV7344, and the part returns to the idle condition.
Figure 48 shows an example of data transfer for a write sequence
and the start and stop conditions. Figure 49 shows bus write and
read sequences.

REGISTER MAP ACCESS
A microprocessor can read from or write to all registers of the
ADV7344 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.

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.
