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.
On-Board Voltage Reference
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 digi-
tal data stream and therefore the output signal.
