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 (96k-bit RAM) ,V-chip data slicer and analog circuitries lead the PIP system low cost and small size.

FEATURES

? Built-in 96k-bit field memory (sub-picture data storage)

? Internal V-chip data slicer (for sub-picture)

? Vertical filter for sub-picture (Y signal )

? Single sub-picture (selectable picture size : 1/9 , 1/16)

? Sub-picture processing sepecification (1/9 size / 1/16 size) : Quantization bits Y, B-Y, R-Y : 6bits Horizontal sampling 171 pixels (Y) , 28.5 pixels (B-Y, R-Y) Vertical lines 69/ 52 lines

? Frame (sub-picture) on/off

? Built-in analog circuits : Two 8-bit A/D converters (main and sub-picture signals) Two 8-bit D/A converters (Y and C sub-picture signals) Sync-tip-clump, VCXO, Analog switch ... etc.

? I2C BUS control (parallel/serial control) : PIP on/off , Sub-picture size(1/9 or 1/16), Frame on/off (programmable luma level), PIP position (4 corners fixed position), Picture freeze , Y delay adjustment, Chroma level, Tint, Black level, Contrast ... etc.
