Philips Semiconductors
Quasi-split sound processor for all standards
Preliminary specification
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
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.
