MITSUBISHI ICs (TV) M52770SP NTSC/PAL TV SIGNAL PROCESSOR DESCRIPTION The M52770SP is a single chip CTV processor which has VIF/SIF, PIN CONFIGURATION (TOP VIEW) luminance, chrominance, mono sound, OSD display, RGB interface, and deflection. I2C And it is possible to control each parameters by bus. A baseband 1H delay line is built-in, and conjunction with SECAM decoder M52325AP simplifies multi system CTV chassis. FEATURES • Built-in 1H Delay Line using Bi-CMOS technology • Multistandard PLL demodulator for IF • Alignment - free sound demodulator • Flexible source selection with internal CVBS and external CVBS or Y/C input signal • Audio switch integrated • Integrated chroma trap and bandpass filters with auto-calibration VIF GND 1 64 VIF VIDEO OUT AFT OUT 2 63 VIF APC FILTER1 SIF LIMITER IN 3 62 VIF VCO (2) RF AGC OUT 4 61 VIF VCO (1) QIF OUT 5 60 FM DIRECT OUT IF AGC FILTER 6 59 EXT AUDIO IN QIF IN 7 58 AUDIO BYPASS SPOT KILLER 8 57 AUDIO OUT VIF IN(1) 9 56 VIF APC FILTER2 VIF IN(2) 10 55 -(R-Y) IN VIF VCC 11 54 -(B-Y) IN FAST BLK 12 53 Hi VCC • Luminance delay line integrated SCL 13 • RGB control circuit with cut-off and drive SCP OUT 14 H OUT 15 • Horizontal synchronaization with two control loops and alignment- VSS 16 free H-oscillator SDA • Vertical saw tooth generator integrated • I2C Bus control of various functions VDD DECOUPLING 18 AFC 1 FILTER 19 • Supply current pin11 and pin31....................................... 107mA pin27 and pin53..........................................56mA • Input signals VIF input sensitivity...................................47dBµ SIF limiting sensitivity............................... 40dBµ 47 Y SW OUT 46 VIDEO/CHROMA GND 45 TV IN 21 44 CHROMA APC FILTER R OUT 22 43 EXT IN G OUT 23 42 KILLER FILTER B OUT 24 41 X-TAL 3.58 DEFLECTION GND 25 40 CONTRAST CONTROL V OUT(RAMP/PULSE) 26 39 R IN START-UP VCC 27 38 BLK HOLD B IN 28 37 G IN V RAMP FEEDBACK 29 36 X-RAY IN V RAMP C 30 35 VIDEO IN • Supply voltage pin11(VIF), pin31(video/chroma).................. 5.0V pin27(Start-up), pin53(Output Stage)........... 9.0V 48 SYNC SEP IN(1) 20 APPLICATION QUICK REFERENCE DATA 49 SYNC SEP IN(2) H OSC • Small amount of peripheral components NTSC/PAL TELEVISION 50 X-TAL 4.43 MUTE FILTER • Easy interfacing with SECAM decoder for multistandard applications 17 51 VIDEO CLAMP M52770SP • Linear RGB inputs and fast blanking • Vertical count-down circuit 52 SECAM REF.
