Function
This pin is connected to the
reference oscillator circuit.
The reference oscillator is working
as a negative impedance
converter. It presents a negative
resistance in series to an
inductance at the COSC pin.
Digital amplitude modulation can
be imparted to the Power Amplifier
through this pin.
A logic high (ASKDTA > 1.5 V or
open) enables the Power
Amplifier.
A logic low (ASKDTA < 0.5 V)
disables the Power Amplifier.
