ADV7176AKS

The ADV7176AKS is a digital video encoder integrated circuit manufactured by Analog Devices, part of the ADV7175A/ADV7176A family designed to convert CCIR-601 4:2:2 component digital video streams into standard-definition analog PAL and NTSC signals. It integrates three 10-bit video digital-to-analog converters and supports simultaneous composite (CVBS), S-Video (Y/C), and component (RGB or YPrPb) outputs, with programmable features accessed via an I²C‑compatible serial interface for adjusting subcarrier frequency, phase, luminance filtering, and closed captioning insertion. A flexible pixel port accepts CCIR‑656 and other industry‑standard timing modes, while on‑chip color bar generation and an internal voltage reference simplify system bring‑up and test.

Typical applications include industrial vision processing, avionics cockpit displays, military video distribution units, medical imaging recorders, and surveillance systems where a reliable bridge between digital processing back‑ends and legacy analog monitors or transmission links is essential. The device is housed in a 44‑lead MQFP surface‑mount package suited to space‑constrained designs. As a member of a mature product family, the ADV7176AKS carries inherent lifecycle considerations; procurement engineers should verify the current obsolescence status with Analog Devices and evaluate long‑term supply continuity. The suffix code indicates a commercial or industrial temperature grade in this series; for defense or aerospace programs requiring extended temperature ranges or additional screening, the exact ordering code must be cross‑referenced against the manufacturer’s documentation. Authorized sourcing is strongly recommended to mitigate counterfeiting risks in high‑reliability deployments.
