MITSUBISHI ICs (TV) M52340SP PAL/NTSC SYSTEM SHINGLE-CHIP COLOR TV SIGNAL PROCESSOR Description The M52340SP is a single-chip semiconductor integrated circuit to process signals of a color TV. Circuits to process video IF, sound IF, video, color, and deflection signals, a I2C bus control circuit, and D/A are build in this device. This IC can be used not only for popular-type TV sets but also for middle-class TV sets. Combined with a SECAM chroma decoder, the M52325AP, this device can process signals of every type of TVs in the world by discriminating them fully automatically. PIN CONFIGURATION (TOP VIEW) Features •A built-in I C bus control circuit makes it possible to reduce the number of peripheral parts and rationalize production lines. •Various filters (TRAP, BPF, Y-DL, RGB clamp) are build in this IC. •PLL detection system is introduced to process video IF and voice IF. Furthermore, AFT coil is not necessary. •DL aperture control •Color signal frequency and vertical frequency of TVs of every type can be discriminated fully automatically. •Horizontal/vertical countdown system •V-pulse output •RGB output 2 AFT OUT LIMITER IN RF AGC OUT IF AGC FILTER VIF GND VIF IN VIF IN VIF VCC H VCC IIL VCC SCL SCP OUT H OUT H OSC SDA AFC 1 FILTER INTERFACE GND V PULSE OUT AFC 2 FILTER Hi VCC R OUT G OUT B OUT VCD VCC B IN CONTRAST CONT. 1 2 3 4 5 6 7 8 9 10 11 52 51 50 49 48 47 46 45 44 43 42 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 VIDEO OUT VIDEO APC FILTER VCO VCO FM DIRECT OUT ATT VCC AUDIO OUT -(R-Y) IN -(B-Y) IN -(R-Y) OUT SECAM REF. -(B-Y) OUT SYNC SEP IN X-TAL 4.43 V(Y) SW OUT VCD GND TV IN (Y IN) CHROMA APC FILTER KILLER FILTER AUDIO BYPASS X-TAL 3.58 FAST BLK AC-IDENT R IN COINCIDENCE G IN Outline 52P4B M52340SP APPLICATION PAL/NTSC system color TV NC : NO CONNECTION RECOMMENDED OPERATING CONDITION Supply voltage .. 4.75V to 5.25V (pins 8 and 24) …7.6V to 8.4V (pins 9, 20, and 47) Rated supply voltage 5.0V (pins 8 and 24) .8.0V (pins 9, 20, and 47) Maximum output current . 5.0mA (pin 18) . 5.0mA (pin 13) BLOCK DIAGRAM VCO VIDEO APC FILTER IIL VCC Hi V CC VIF VCC AUDIO ATT BYPASS VCC VIDEO OUT LIMITER IN VIF GND IF AGC FILTER FM DIREC T OUT 4 51 AUDIO ATT SW AUDIO MUTE SW SYSTEM DECODE SYSTEM auto B EXT INPUT ID OUT SYSTEM ID REF FILTER BRIGHT DRIVE AMP LAMP V SYNC TRIG SECAM REF EO ELIMINATE TV/ EXT KILLER DET F/F BIGP GENE PAL SW PHASE CONT TINT AFC GAIN VCXO AFC-1 32FH VCO MUTE DET MUTE OUT H-PHASE AFC-2 50/60 OUT V.PULSE HORIZONTAL COUNT DOWIN H STOP VERTICAL COUNT DOWIN SERVICE SW CONTRAST CHROMA DEMODULATOR SYNC SEP RGB MATRIX CONTRAST COLOR SERVICE BRIGHT G EXT INPUT DRIVE R B CUT OFF R G B R EXT INPUT SYSTEM SET 4.5/6.0 BUS I/F LOCK DET LIMITER FM DET ATT AF AMP […]
