-CHIP TV PROCESSOR IC FOR VISION AND SOUND IF PROCESSING , VIDEO AND SYNCHRONIZATION FOR B /W TV

IC DESCRIPTION

KK A8362W 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).
