1-CHIP DEFECTION SYSTEM CD1379CP
DESCRIPTION
Outline Drawing
The CD1379CP consists of a vertical
system including function and a horizontal
system including an AFC function . It is
for use in small size color TV, B/W TV
receivers and monitors.
FUNCTIONS
Horizontal Section
SYNC separation
Horizontal Oscillators
Horizontal Pre-drivers
Horizontal AFCs
Shunt Regulator(Typical 6.7V)
Vertical Section
Vertical Oscillator
Vertical Pre-drivers
Vertical Output
Fly-back generators
FEATURES:
Low Power consumption, direct deflection coil driving capability (Fly-back
voltage two times as high supply voltage is supplied during fly-back period only)
Variable circuit of vertical retrace time on chip
