Package P-DIP-20
Circuit Description
The IF circuit consists of a four-stage capacitively coupled and symmetrically designed controlled amplifier and a real synchronous demodulator with a FPLL-carrier regeneration. Two IF inputs can be selected for applications with different SAWs. The main performance of the device is the very low differential phase DP and gain DG bined with an excellent intermodulation ratio. The positive video output is used to derive the IF and tuner control voltage. The AGC threshold is set by means of a potentiometer. Dependent on the modulation polarity the video signal and the AGC are switched over. MAC state can be selected by an additional signal. Application Multistandard TV/VTR and cable converters with mono or stereo applications.
