GENERAL DESCRIPTION
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 either
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 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 ADV7344 also supports embedded EAV/SAV timing codes,
external video synchronization signals, and I
communication protocols.
In addition, simultaneous SD and ED/HD input and output is
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.
