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
either standard definition (SD), enhanced definition (ED), or
high definition (HD) video formats.
The ADV7342/ADV7343 each have a 24-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 parts also support embedded EAV/SAV timing codes,
external video synchronization signals, and I2C and SPI
communication protocols.
In addition, simultaneous SD and ED/HD input and output are
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.
Table 1 lists the video standards directly supported by the
ADV7342/ADV7343.
