... Mar 26 APPLICATIONS Direct Broadcast Satellite (DBS) receivers. GENERAL DESCRIPTION The TDA8012M is a sensitive PLL FM demodulator which is used for the second IF in satellite receivers. It provides Automatic Gain Control (AGC) and Automatic Frequency Control (AFC) outputs that can be used to optimize the level and frequency of the input signal. During the searching procedure, the AFC output provides a signal which is used for carrier detection ...

... An analog AFC voltage is also made available. This signal can be suitably applied to the input of the ADC port of the PLL frequency synthesizer (TSA5055). The AFC function may be keyed to address D2MAC and MUSE systems. The TDA8012M includes a Carrier Detector (CD) which is used for channel detection during search procedures. 4 Product specification ...
