GENERAL DESCRIPTION
The ADV
7330 is a high speed, digital-to-analog encoder on a
single monolithic chip. It includes three high speed video D/A
converters with TTL compatible inputs.
The ADV7330 has separate 8-bit or 16-bit input ports that
accept data in high definition or standard definition video
format. For all standards, external horizontal, vertical, and
blanking signals or EAV/SAV timing codes control the inser-
tion of appropriate synchronization signals into the digital
data stream and therefore the output signal.
