Simplified Functional Block Diagram 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.
