描述 Description

The M65665CFP/SP 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) for NTSC.
The built-in field memory (168k-bit RAM) , V-chip data slicer and analog circuitries lead the high quality PIP system low cost and small size.
