| MITSUBISHI ICs (TV) M52779SP VIF, SIF, VIDEO, CHROMA, DEFLECTION FOR PAL/NTSC DESCRIPTION The M52779SP 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.
