GENERAL DESCRIPTION

The ADV®7324 is a high speed, digital-to-analog encoder on a single monolithic chip. It includes six high speed NSV video DACs with TTL-compatible inputs. It has separate 8-/10-, 16-/20-, and 24-/30-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.
