M65665SP

MITSUBISHI DIGITAL TV ICs M65665SP/FP PICTURE-IN-PICTURE SIGNAL PROCESSING DESCRIPTION The M65665SP/FP 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) f or NTSC, PAL-M, and PAL-N. The built-in f ield memory (168k-bit RAM) , V-chip data slicer and analog circuitries lead the high quality PIP sy stem low cost and small size. APPLICATION NTSC, PAL-M, PAL-N color TV RECOMMENDED OPERATING CONDITIONS Supply v oltage range ------------------------ 3.2 ~ 3.5 V Operating f requency ----------------------- 14.32 MHz Operating temperature ------------------------ 0 ~ 70 deg. Input v oltage (CMOS interf ace) "H" ----- VDD x 0.7 ~ VDD V "L" ----0 ~ VDD x 0.3 V Output current ( output buf f er ) ------------ 4 mA ( MAX ) Output load capacitance ---------------------- 20 pF ( MAX ) *1 Circuit current ----------------------------------mA FEATURES * * * * * Internal V-chip data slicer (f or sub-picture) NOTICE: Connect a 0.1µF or larger capacitor between VDD and VSS pins.
