FUNCTIONAL DESCRIPTION
The TDA8012M is a low power PLL FM demodulator
designed for use in satellite TV reception systems.
The demodulator is based on a Phase-Locked Loop (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 via a highly linear video buffer
which has a low output impedance. The centre frequency
of the VCO and the loop characteristics can be set using
external components.
The circuit provides an AGC signal which is used to drive
a gain-controlled IF amplifier (TDA8011T or TDA8010M)
to ensure a stable PLL demodulation characteristic.
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.
