GENERAL DESCRIPTION
The ADV®7322 is a high speed, digital-to-analog encoder on a
single monolithic chip. It includes six high speed video DACs
with TTL compatible inputs. It has separate 8-, 16-, 24-bit input
ports that accept data in high definition and/or standard
definition 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 signal.
