TDA3858 - Quasi-split sound processor

Datasheet Summary

Description

Separate symmetrical IF inputs for FM or AM sound.

Gain controlled wideband IF amplifier, input select switch.

AGC generation due to peak sync for FM or mean signal level for AM.

Features

  • Quasi-split sound processor for all standards e. g. B/G (FM sound) and L (AM sound).
  • Reducing of spurious video signals by tracking function and AFC for the vision carrier reference circuit; (recommended for NICAM).
  • Automatic muting of the AF2 signal (at B/G) by the input level.
  • AM signal processing for L standard and switching over the audio signal.
  • Stereo matrix correction.
  • Layout-compatible with TDA3856 (24 pins) and TDA3857 (20 pins). GE.
