Functional Description

Pin Symbol Interface Schematic

No.

Function

7

FSKDTA

Digital frequency modulation can

VS

+1.2 V

be imparted to the Xtal Oscillator by

this pin. The VCO-frequency varies

60 kΩ

7

90 kΩ

in accordance to the frequency of

the reference oscillator.

+1.1 V A logic high (FSKDTA > 1.5V or

open)

30 µA 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.
