Description
The M65667FP is a NTSC PIP (Picture in Picture) signal processing LSI, whose sub and main-picture inputs are
composite and Y/C separated signals, respectively. The built-in field memory (96 Kbit RAM), V-chip data slicer and
analog circuitries lead the PIP system low cost and small size.
