Preliminary speciﬁcation

Quasi-split sound processor for all standards

TDA3866

FEATURES

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

(FM sound) and L (AM sound)

• AF2 signal automatically muted (at B/G) by the input

signal level

• AM signal processing for L standard and switching over

the audio signal

• Stereo-matrix correction

• Layout-compatible with TDA3858 (32 pins) and

TDA3857 (20 pins)

• AM output level typically 500 mV at m = 0.54 (+2.5 dB in

comparison to TDA3856)

GENERAL 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. Reference amplifier for the regeneration of

the vision carrier. Optimized limiting amplifier for AM

suppression in the regenerated vision carrier signal and

° 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.
