TECHNICAL DATA
SINGLE-CHIP TV PROCESSOR IC FOR VISION AND SOUND IF
PROCESSING, VIDEO AND SYNCHRONIZATION FOR B/W TV
IC DESCRIPTION
KKA8362W is intended for b/w TV receiver and contain functional units for video and
sound IF signals, line and frame synchronization , output Y-signal.
IC FEATURES
circuit for processing Vision IF (positive and negative modulation).
FM sound demodulator (4.5-6.5 МHz).
Addition inputs for A/V (external and internal video inputs, internal and external audio inputs).
Embedded delay line for brightness signal.
control IC for output Y-signal and external Y-input and possibility of a direct information display on screen
(OSD
mode).
Line synchronisation with two control circuits and a generator (adjustment is not needed).
IC for frame divider and preamplifier of frame scanning.
Low power consumption (500 mW).
Minimum quantity of external parts.
Only one adjustment is required (IF demodulator).
