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.
