This document introduces ADV7195's functional characteristics, including input formats, output formats, functional blocks, etc.
The ADV7195 is a triple high‑speed digital‑to‑analog video encoder on a single monolithic chip. It offers three 10‑bit‑wide input ports supporting YCrCb and RGB formats and outputs analog YPrPb or RGB signals compliant with various HDTV standards. The device operates from a single 3.3 V supply and includes programmable features such as test‑pattern generation, gamma correction, and adaptive filter control.
The document contains a functional block diagram, detailed electrical specifications, timing diagrams, absolute maximum ratings, ordering information, and a full pin‑out layout for the 52‑lead MQFP package. It is intended for designers integrating the encoder into progressive‑scan HDTV, video projection, or digital video systems.

The ADV7195 requires a single 3.3 V power supply and optionally an external 1.235 V reference.
It accepts YCrCb 4:4:4 10‑bit, RGB 4:4:4 10‑bit, and YCrCb 4:2:2 10‑bit input formats.
The ADV7195 is offered in a 52‑lead plastic quad flat‑pack (MQFP) package.
