LC89978M Overview
EN5546A CMOS LSI LC89978M CCD Delay Line for Multi-System Overview The LC89978M is a CCD delay line for multi television system that incorporates a b filter to remove noise from the chrominance signal and a 1-H delay line for the luminance signal. mm 3111-MFP14S [LC89978M].
LC89978M Key Features
