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 circui ts 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). Block diagram of TV signal processor ILA 8362 W ВЫХОДНОЙ Y КАСКАД SOUND PREAMPL. VOLUME COMTROL SOUND SWITCH SYNC SEPARATOR PHASE 1 DET.
