M65667FP Datasheet | Mitsubishi Electric

MITSUBISHI ICs (TV) PRELIMINARY Notice:This is not a final specification. Some parametric limits are subject to change. PICTURE-IN-PICTURE SIGNAL PROCESSING DESCRIPTION The M65667FP is a NTSC PIP (Picture in Picture) signal processing LSI, whose sub and main-picture inputs are posite and Y/C separated signals, respectively. The built-in field memory (96k-bit RAM) ,V-chip data slicer and analog circuitries lead the PIP system low cost and small size.
