Function
Digital frequency modulation can
be imparted to the Xtal Oscillator by
this pin. The VCO-frequency varies
in accordance to the frequency of
the reference oscillator.
A logic high (FSKDTA > 1.5V or
open)
sets the FSK switch to a high
impedance state.
A logic low (FSKDTA < 0.5 V)
closes the FSK switch
from FSKOUT (pin 4) to GND (pin
3).
A capacitor can be switched to the
reference crystal network this way.
The Xtal Oscillator frequency will
be shifted giving the designed FSK
frequency deviation.
