Video IF with FPLL, MAC State TDA 6050-5 Bipolar IC Features q Active multistandard video IF with FPLL demodulator q 12-MHz bandwidth q MAC state P-DIP-20 Type TDA 6050-5 Ordering Code Q67000-A5123 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 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. Application Multistandard TV/VTR and cable converters with mono or stereo applications.
