Description: Intercarrier Mixer and AM-Demodulator for TV and VCR

Features

* D Very high input sensitivity D Excellent signal-to-noise ratio D Intercarrier output signal gain controlled and independent from the picture carrier to sound carrier ratio D Few external components D ESD protected D AM demodulator alignment free Case: DIP14 Block Diagram AGC 7 14 +VS 13 1 IF I

Applications

* in TV-sets and VCR. This circuit has separate inputs for the soundand picture carrier. The sound carrier signal (single or dual carrier, modulated with AM, FM or NICAM) from the SAW filter will be fed into a 3-stage, gain controlled, IF amplifier (Pin 1 and 2). The following two mixer stages operate
