GENERAL DESCRIPTION
The ADV7390/ADV7391/ADV7392/ADV7393 are a family of
high speed, digital-to-analog video encoders on single
monolithic chips. Three 2.7 V/3.3 V 10-bit video DACs provide
support for composite (CVBS), S-Video (YC), or component

(YPrPb/RGB) analog outputs in either standard-definition (SD)
or high-definition (HD) video formats.
Optimized for low power operation, occupying a minimal
footprint and requiring few external components, these
encoders are ideally suited to portable and power sensitive
applications requiring TV-Out functionality. Cable detection
and DAC auto power-down features ensure that power
consumption is kept to a minimum.
The ADV7390/ADV7391 have an 8-bit video input port that
supports SD video formats over a SDR interface and HD video
formats over a DDR interface.
The ADV7392/ADV7393 have a 16-bit video input port that
can be configured in a variety of ways. SD RGB input is
supported.
All members of the family support embedded EAV/SAV timing
codes, external video synchronization signals and the I
SPI communication protocols.
Table 1 lists the video standards directly supported by the
ADV739x family.
