TDA3857 - Quasi-split sound processor

Datasheet Summary

Description

Symmetrical IF inputs.

Gain controlled wideband IF amplifier.

AGC generation due to peak sync.

Features

  • Quasi-split sound processor for all FM standards e. g. B/G TDA3857.
  • 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 by the input level.
  • Stereo matrix correction.
  • Layout-compatible with TDA3856 (24 pins) and TDA3858 (32 pins).
