... SSOP20 plastic shrink small outline package; 20 leads; body width 4.4 mm 1997 May 26 GENERAL DESCRIPTION The TDA8012AM is a sensitive Phase Locked Loop (PLL) Frequency Modulation (FM) demodulator for the second Intermediate Frequency (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 the frequency of the signal applied at the input ...

... FUNCTIONAL DESCRIPTION The TDA8012AM is a low power PLL FM demodulator designed for use in satellite TV reception systems. The demodulator is based on a PLL structure including a fully balanced two-pin VCO. A high gain IF amplifier ensures a high input sensitivity. The video output voltage is supplied through a highly-linear video buffer with a low output impedance ...
