TECHNICAL DATA
SINGLE-CHIP TV PROCESSOR IC FOR VISION AND SOUND IF
PROCESSING, VIDEO AND SYNCHRONIZATION FOR B/W TV
IC DESCRIPTION
ILA8362W 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).
