MITSUBISHI ICs (TV) M52778SP VIF, SIF, VIDEO, CHROMA, DEFLECTION FOR PAL/NTSC

DESCRIPTION

The M52778SP 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 C 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

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.
