This data sheet introduces the ADv7340/ADV7341 multiformat video encoder, which can encode various format video inputs (including composite, S-Video, YPrPb, and RGB) to HDCP-compliant SDI output. The encoder uses 6 12-bit Noise Shaped Video (NSV) DACs to provide high-quality video output. The encoder also supports simultaneous SD and ED/HD operation.
The ADV7340/ADV7341 are high‑speed digital‑to‑analog video encoders that support standard definition (SD), enhanced definition (ED) and high definition (HD) video formats. They provide six 12‑bit noise‑shaped video DACs and a variety of output interfaces including composite, S‑Video, component YPrPb and RGB.
The data sheet includes functional block diagrams, pin descriptions, timing specifications, power consumption figures, and programming details for the I²C‑compatible MPU port. It also lists supported video standards, filter options, and test‑pattern generation capabilities.
