It includes six high speed video D/A converters with TTL compatible inputs. The ADV7302A/ADV7303A has three separate 8-bit wide input ports that accept data in high definition and/or standard defini- tion 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. |
