Abstract :
A digital adaptive Y/C separator LSI for S-VHS VCR is described. The LSI 1.3-μm rule, two 8-bit DACs (digital-to-analog converters) and an 8-kb line memory. To reduce the chip size, adaptive Y/C separation is done with a one-line memory and a multipurpose filter. Technologies used to realize the Y/C separator are: (1) noncorrelation detection using a one-line memory; (2) technology to reduce the bandwidth for noncorrelation detection; and (3) use of the soft-mix method. This LSI also operates as a dynamic comb filter and a dropout compensator in the playback mode
