This document is about ADV7184 technical data. ADV7184 is a multiformat SDTV video decoder that supports fast switch overlay support.
The ADV7184 is a single‑chip multiformat SDTV video decoder from Analog Devices that automatically detects and converts NTSC, PAL, and SECAM signals from composite, S‑Video, or component sources into digital ITU‑R BT.656 4:2:2 video.
The device integrates four 10‑bit ADCs, a 5‑line adaptive comb filter, and supports fast‑blank SCART overlay, macrovision detection, and VBI data recovery. It runs from a 28.63636 MHz crystal, uses 3.3 V analog and 1.8 V digital core supplies, and is packaged in an 80‑lead LQFP rated for –40 °C to +85 °C.
