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 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.
FEATURES
A built-in I2C 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-Ramp output
RGB output
