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. During the search procedure, the AFC output
provides a signal used for carrier detection.
