GENERAL DESCRIPTION
The ADV®7320/ADV7321 are high speed, digital-to-analog
encoders on single monolithic chips. They include six high
speed NSV video DACs with TTL-compatible inputs. They have
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.
