GENERAL DESCRIPTION

The ADV®7320/ADV7321 are high speed, digital-to-analog encoders on single monolithic chips. They include six high speed NSV video D/A converters with TTL compatible inputs. They have separate 8-/10-, 16-/20-, and 24-/30-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.
