TDA3867T Datasheet | NXP Semiconductors

FEATURES - Quasi-split sound processor for all FM standards e.g. B/G - Reduction of spurious video signals by tracking function and AFC for the vision carrier reference circuit; (indispensable for NICAM) - AF2 signal automatically muted (at B/G) by the input signal level GENERAL DESCRIPTION Symmetrical IF input and 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 m W power dissipation at 5 V.
