M65669FP - Mitsubishi

M65669FP PICTURE-IN-PICTURE SIGNAL PROCESSING

The M65669SP/FP is a PIP (Picture in Picture) signal processing LSI, whose sub-picture input is composite signal for NTSC, PAL-M, and PAL-N. The built-in field memory (144k-bit RAM) , V-chip data slicer and analog circuitries lead the high quality PIP system low cost and small size. RECOMMENDED OPERATING CONDITIONS Supply voltage range ---------------------.
