GENERAL DESCRIPTION

The ADV®7310/ADV7311 is a high speed, digital-to-analog encoder on a single monolithic chip. It includes six high speed NSV video D/A converters with TTL compatible inputs.

The ADV7310/ADV7311 has separate 8-/10-/16-/20-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.
