GENERAL DESCRIPTION
The ADV7322 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-, and 24-bit
input ports that accept data in high definition (HD) and/or
standard definition (SD) 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.
