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. Features • Internal V-chip data slicer (for sub-picture) • Vertical filter for sub-picture ( Y signal ) • Base band com filter (2 Line) • Single sub-picture ( selectable picture size : 1/9 , 1/16 ) • Sub-picture processing specification ( 1/9 , 1/16 size) : Quantization bits Y, B-Y, R-Y : 7 bits Horizontal sampling 229 pixels (Y), 57 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 (for sub-picture signal) Three 8-bit D/A converters (for Y, U and V of sub-picture) Auto Slicer(Sync Sep.), Sync-tip-clamp, VCXO, OSD switch, etc.. • IIC BUS control ( parallel/serial control) : PIP on/off , Frame on/off ( programmable luma level), Sub-picture size ( 1/9, 1/16 ), PIP position ( free position ), Picture freeze , Y delay adjustment, Chroma level, Tint, Black level, Contrast ...etc.. Application NTSC color TV Recommended Operating Conditions Supply voltage range --------------------- 3.2 to 3.5 V Recommended supply voltage --------------------- 3.3 V
