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 sup-
ported 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.
