GENERAL DESCRIPTION
The ADV7302A/ADV7303A is a high speed, digital-to-analog
encoder on a single monolithic chip. It includes six high speed
video D/A converters with TTL compatible inputs.
The ADV7302A/ADV7303A has three separate 8-bit wide input
ports that accept data in high definition and/or standard defini-
tion video format. For all standards, external horizontal, vertical,
and blanking signals, or EAV/SAV timing codes, control the
insertion of appropriate synchronization signals into the digital
data stream and therefore the output signals.
