RF input signal pin.
AGC control input from the demodulator/FEC IC. It controls the gain of the RF attenuator
and both baseband amplifiers. Minimum gain occurs at minimum voltage. Input impedance
zin = 1 MΩ//20 pF..
Baseband filter control input from the demodulator/FEC IC.
Minimum BW occurs at minimum voltage. Zin = 17 kΩ//20 pF.
