M52340SP

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.
