ADV7185 is a professional NTSC/PAL video decoder from ADI, supporting 10-Bit CCIR656 output.
The ADV7185 integrates two 12‑bit ADCs clocked from a single 27 MHz crystal and supports dual video clocking schemes (Line‑Locked Clock and Adaptive Digital Line Length Tracking). It provides a 3‑line chroma comb filter, real‑time clock and status outputs, automatic gain control, and clamping for six analog video input channels, handling CVBS, SVHS, and YCrCb component signals.
The device offers extensive digital output options, including 20‑bit YCrCb formats, and includes programmable video controls for brightness, contrast, hue, and saturation. Electrical specifications cover a 5 V analog supply, 3.3 V digital I/O, and a maximum operating temperature of 70 °C, making it suitable for professional video equipment, broadcast, and surveillance applications.
