MITSUBISHI ICs (TV) M52775FP VIF, SIF, VIDEO, CHROMA, DEFLECTION FOR NTSC DESCRIPTION APPLICATION The M52775FP is desinged to provide a solution to NTSC color NTSC type color TV, projecter 2 television system. It is an I C bus controlled NTSC 1 chip. It consists of various processing blocks such as video IF, sound IF, luminance, RECOMMENDED OPERATING CONDITION chrominance, mono-sound, OSD display, interface, H and V Recommended supply voltage.....................V3, 4, 21, 22, 23=4.75V deflection. At each block, I2C control is possible and a total of 30 V5, 15, 16=8.0V parameters can be controlled by I C bus. Supply voltage range........................V3, 4, 21, 22, 23=4.50 to 5.00V FEATURES Maximum output current.............................................3.0mA (pin14) 2 V5, 15, 16 =7.6 to 8.8V • • • • • • • • • • • • 4.0mA (pin13) AFT coil-less FM det coil-less Dynamic AGC AV switch (TV/EXT video) Y/C switch Built-in black stretch circuit Delay line aperture control Luminance peak limiter Two window vertical countdown Built-in chroma BPF and Trap Built-in Y Delay line Built-in ACC/Killer filters 8.0mA (RGB output current) 3.0mA (AUDIO OUT output current) 33 GND 34 VIDEO SW IN 35 CHROMA APC FILTER 36 EXT/C IN 37 VCD GND1 38 VCD GND2 39 VCD GND3 40 Y SW OUT 41 TV/Y IN 42 SYNC SEP IN 44 COINCIDENCE 43 VIDEO SW OUT 46 ABL 45 γ-CONT 47 LIMITER IN 48 GND PIN CONFIGURATION (TOP VIEW) 32 X-TAL 3.58 AUDIO SW OUT 49 31 AUDIO BYPASS AUDIO IN 50 30 FAST BLK AUDIO OUT 51 29 BLACK PEAK HOLD FM DIRECT OUT 52 28 R IN EXT AUDIO IN 53 VCO 54 27 AFC 2 FILTER VCO 55 26 G IN VIDEO APC FILTER 56 25 CONTRAST CONT M52775FP VIDEO OUT 57 24 B IN AFT OUT 58 23 VCD VCC3 RF AGC OUT 59 22 VCD VCC2 IF AGC FILTER 60 21 VCD VCC1 IF GND1 61 20 B OUT IF GND2 62 19 G OUT IF GND3 63 18 R OUT IF IN 64 Outline 64P6N-A 1 Hi VCC2 16 Hi VCC1 15 V PULSE 14 FBP INV OUT 13 AFC 1 FILTER 12 H OSC 11 SDA 9 H OUT 10 FBP IN 8 SCL 7 H VCC 5 IIL VCC 6 IF VCC1 3 IF VCC2 4 IF IN 2 GND 1 17 GND IF IN 64 ON/OFF MUTE SW DL Fine Adj Y SW OUT 40 X2 10 27 11 13 12 8 44 42 AFC-2 32 INV 32FH VCO HORIZONTAL COUNT DOWN VERTICAL COUNT DOWN R G B CUT OFF (8) HV BLK X-TAL 3.58 35 AFC-1 AFC GAIN V SYNC TRIG CLAMP SYNC SEP IN CHROMA APC FILTER 39 COINCI.
