GENERAL DESCRIPTION
The ADV
single monolithic chip. It includes six high speed NSV video
D/A converters with TTL compatible inputs.
The ADV7314 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 inser-
tion of appropriate synchronization signals into the digital data
stream and therefore the output signal.
