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.
