KS0118C
INTRODUCTION
T he KS0118C is a CMOS integrated circuit designed for the GEN LOCK and ND Conversion. It is a Monolithic IC that enabled an analog NTSC composite video signal to digitize at a clock rate that is synchronized and locked to the incoming video horizontal line frequency. It includes clamping function, 8-bit digitizing and creation of a line locked sampling clock. It is possible to correspond to the video signal system of LDP by the use of KA9413, KA 9414-D ICS together, which is designed for the Digital Video Signal Processor. 80-QFP-1420C
