M65669FP

PRELIMINARY Notice ; This is not the final specification. Some of information in this document are subject to changes. MITSUBISHI DIGITAL TV ICs M65669SP/FP V3.1 APPLICATION NTSC, PAL-M, PAL-N color TV PICTURE-IN-PICTURE SIGNAL PROCESSING DESCRIPTION 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 ---------------------------------- 3.1 ~ 3.5 V Operating frequency --------------------------------- 14.32 MHz Operating temperature --------------------------------- -10 ~ 70 deg. Input voltage (CMOS interface) "H" ----- VDD x 0.7 ~ VDD V "L" ----0 ~ VDD x 0.3 V Output current ( output buffer ) ------------------- 4 mA ( MAX ) Output load capacitance --------------------------- 20 pF ( MAX ) *1 Circuit current ---------------------------------------- mA FEATURES * Built-in 144k-bit field memory ( sub-picture data storage) * Internal V-chip data slicer (for sub-picture) NOTICE: Connect a 0.1µF or larger capacitor between VDD and VSS pins. * Vertical filter for sub-picture ( Y signal ) *1 : Include pin capacitance ( 7 pF ) * 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 : 6 bits Horizontal ...
