The CXA1686M is a clock pulse generator IC produced by the Sony company which is widely used in Changhong NC-3 cassette mechanism series large-screen color TV sets. 1.Its functional features. The CXA1686M IC's internal part is mainly made up of three parts which are video signal selection circuit, clamp pulse forming circuit and 4fsc clock pulse forming circuit and so on. Its internal circut diagram and pin's function is shown in picture 1. The picture 1 shows the CXA1686M IC's internal circuit diagrama nd pin's function. The CXA1686M IC is generally used to coordinate with SBX1765-01 thick-film comb filter circuit to make up the Y/C separation circuit. The CXA1686M's function is supplying the necessary clamp pulse signal, comb filter working mode control signal and the chroma signal genlocking's 4fsc clock signal for the comb filter circuit SBX1765-01.
