A video signal processing system is presented to realize an adjustment-free system. The proposed system is trimmable for the electrical characteristics of LSI after final assembly using a serial data control and fusible links. In this case, trimming is done by the information of a serial data control, which requires only 3 additional pins. The adjustment-free LSI for use in VCRs is fabricated using a BICMOS process with 1.2 /spl mu/ design rules, operating on a main power supply voltage of 5 V.
