TDA3857 Datasheet - NXP

TDA3857 Quasi-split sound processor with two FM demodulators

Symmetrical IF inputs. Gain controlled wideband IF amplifier. AGC generation due to peak sync. Reference amplifier for the regeneration of the vision carrier. Optimized limiting amplifier for AM suppression in the regenerated vision carrier signal and 90° phase shifter. Intercarrier mixer for FM sou.

TDA3857 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
