FUNCTIONS AND EXPLANATION
Input frequency from an external VCO output.
Must be coupled with capacitor (e.g. 1 000 pF) for DC cut.
Supply voltage 5.0±0.5 V for operation. Must be connected bypass capacitor
(e.g. 1 000 pF) to minimize ground impedance.
Divided ratio control can be governed by following input data to these pins.
