描述 Description

The CXA2060BS is a bipolar IC which integrates the luminance signal processing, chroma signal processing, RGB signal processing, and sync and deflection signal processing functions for PAL/NTSC/SECAM system color TVs onto a single chip. This IC includes deflection processing functions for wide-screen TVs. With a SECAM decoder and 1H delay line built in for PAL/SECAM, this IC can be used in configuring multi-color system TV set.
