M65667FP

MITSUBISHI ICs (TV) PRELIMINARY Notice:This is not a final specification. Some parametric limits are subject to change. M65667FP 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 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. APPLICATION NTSC color TV RECOMMENDED OPERATING CONDITION Supply voltage range........................................................3.1 to 3.5V Operating frequency.........................................................14.32 MHz Operating temperature....................................................-20 to 75 °C Input voltage (CMOS interface) "H"........................V DD×0.7 to VDD V "L".............................0 to VDD×0.3V Output current (output buffer)........................................ ±4mA (MAX) Output load capacitance............................................20pF (MAX) ∗1 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 ...
