The SAA7118 is a video capture device for applicaTIons atthe image port of VGA controllers.Philips X-VIP is a new mulTIstandard comb filter videodecoder chip with addiTIonal component processing,providing high quality, opTIonally scaled, video.The SAA7118 is a combination of a four-channel analogpreprocessing circuit including source selection,anti-aliasing filter and ADC with succeeding decimationfilters from 27 to 13.5 MHz data rate. Each preprocessingchannel comes with an automatic clamp and gain control.The SAA7118 combines a Clock Generation Circuit(CGC), a digital multistandard decoder containingtwo-dimensional chrominance/luminance separation by anadaptive comb filter and a high performance scaler,including variable horizontal and vertical up anddownscaling and a brightness, contrast and saturationcontrol circuit.
