1 / 44 page  PAL/NTSC SYSTEM SHINGLE-CHIP COLOR TV SIGNAL PROCESSOR M52340SP MITSUBISHI ICs (TV) 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 I 2C 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. FEATURES •A built-in I 2C 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 APPLICATION PAL/NTSC system color TV 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) PIN CONFIGURATION (TOP VIEW) Outline 52P4B 52 VIDEO OUT VIDEO APC FILTER VCO VCO FM DIRECT OUT NC : NO CONNECTION ATT VCC 51 50 49 48 47 46 45 44 43 41 39 37 35 33 42 40 38 36 34 32 31 30 29 28 27 1 2 3 4 5 6 7 8 9 10 12 14 16 18 20 11 13 15 17 19 21 22 23 24 25 26 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 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. |
