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
