This document describes a multiformat SDTV video decoder with fast switch overlay support. The decoder supports various video standards and integrates four 54 MHz, Noise Shaped Video (NSV), 12-bit ADCs. It also features SCART fast blank support, clocked from a single 28.63636 MHz crystal, Adaptive Digital Line Length Tracking (ADLLT), signal processing, and enhanced FIFO management for mini-TBC functionality. Other features include 5-line adaptive comb filters, a proprietary architecture for locking to weak, noisy, and unstable video sources such as VCRs and tuners, subcarrier frequency lock and status information output, integrated automatic gain control (AGC) with adaptive peak white mode, Macrovision® copy protection detection, chroma transient improvement (CTI), digital noise reduction (DNR), and more.
The ADV7188 video decoder from Analog Devices automatically detects and converts NTSC, PAL and SECAM signals from composite, S‑video and component sources into digital video formats. It features four 12‑bit NSV ADCs, a 28.63636 MHz clock, and a 5‑line adaptive comb filter for high‑quality output.
Designed for applications such as DVD recorders, set‑top boxes, video projectors and security cameras, the device includes programmable video controls, Macrovision copy‑protection detection, and a 2‑wire I²C‑compatible serial interface for configuration.
