INTEGRATED CIRCUITS DATA SHEET TDA3866 Quasi-split sound processor for all standards Preliminary specification File under Integrated Circuits, IC02 January 1992 Philips Semiconductors Preliminary specification Quasi-split sound processor for all standards 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 TDA3866 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.
