The ADV7184 is a high performance multi-format SDTV video decoder with fast switch overlay support. This device integrates four 54 MHz, 10-bit ADCs, supports NTSC, PAL and SECAM video formats, and supports SCART fast blanking function. It also uses a 28.63636 MHz crystal locked clock.
The ADV7184 is a single‑chip, multiformat video decoder that automatically detects and converts NTSC, PAL, and SECAM signals from composite, S‑Video, and component sources into a digital ITU‑R BT.656 output. It includes four 10‑bit ADCs, a 12‑channel input MUX, and optional antialiasing filters, making it suitable for DVD recorders, set‑top boxes, security systems, and professional video equipment.
The datasheet provides full electrical, video, timing, analog, and thermal specifications, as well as pin descriptions, register maps, typical circuit connections, and ordering information. It also outlines power‑down mode, I²C‑compatible serial interface, and package details for the 80‑lead LQFP device.
