ADV7172/ADV7173 is a digital PAL/NTSC video encoder with six 10-bit video DACs, color control and enhanced power management features.
The ADV7172/ADV7173 is a digital video encoder that converts CCIR‑601 4:2:2 component video data into standard analog PAL/NTSC signals. It supports a wide range of video standards and includes six 10‑bit DACs with programmable color and power‑management features, making it suitable for DVD playback, portable video equipment, set‑top boxes, and other multimedia applications.
This handbook describes the device’s features, functional block diagram, electrical specifications, timing diagrams, and allowable operating configurations. It also covers power‑supply options, DAC current settings, and programming via a two‑wire serial interface.
