PAL/NTSC SYSTEM SHINGLE-CHIP COLOR TV SIGNAL PROCESSOR
M52340SP
MITSUBISHI ICs (TV)
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 I
2
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
A built-in I
2
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.
Horizontal/vertical countdown system
V-pulse output
RGB output
