It includes six high speed video D/A converters with TTL compatible inputs. The ADV7300A/ADV7301A has three separate 10-bit wide 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 signals.
