The Advanced PAL Comb FilterII is a video signal processor for VCRs, LDPs, and TVs. It separates the Luminance Y and Chrominance C signal from the NTSC/PAL composite signal by using digital signal processing techniques which minimize dotcrawl and crosscolor. The builtin 4xFSC PLL circuit allows a subcarrier signal input, which generates 4xFSC clock for video signal processing. This filter allows a video signal input of an extended frequency bandwidth by using a 4xFSC clock. The builtin vertical enhancer circuit reduces noise and dot crawl on the Luminance Y signal. The builtin A/D and D/A converters allow easy connection to analog video circuits.
