TDA4340X - Stereo Decoder/Noise Blanker

General Description

Power Supply, Reference Current A temperature stable, low noise reference voltage generator is used for better ripple rejection and for the generation of a reference current.

Key Features

  • Internal reference voltage source.
  • Adjustment free oscillator with ceramic resonator 456 kHz.
  • Pilot dependent mono/stereo switching with hysteresis P-DSO-20-1.
  • Stereo indicator output.
  • Analogue control of mono/stereo change over (stereo noise control, SNC).
  • Pilot canceller (19 kHz).
  • Adjacent channel noise suppression (114 kHz).
  • MUTE facility.
  • Analogue control of deemphasis (high cut control, HCC).
  • Stereo.
