Quasi-split sound processor with two

FM demodulators

TDA3857

FEATURES

• Quasi-split sound processor for all FM standards e. g. B/G

• 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).

GENERAL DESCRIPTION

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 sound, output with low-pass filter.

Separate signal processing for 5.5 and 5.74 MHz intercarriers. Wide supply voltage range, only 300 mW power

dissipation at 5 V.
