DESCRIPTION

The M65665SP/FP is a PIP (Picture in Picture) signal processing LSI, whose sub-picture input is composite signal or component signals(Y/C or Y/U/V) f or NTSC, PAL-M, and PAL-N. The built-in f ield memory (168k-bit RAM) , V-chip data slicer and analog circuitries lead the high quality PIP sy stem low cost and small size.

FEATURES
