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.
