TDA 6051-5X
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 combined 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.
