Functional Description

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

5 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.
