Electronic – Controlling the frequency of oscillation of SI530 VCXO

clock

I am thinking of using the SI530 VCXO as a means to generate clock signal at frequency of 1.4 GHz.

But in the datasheet I do not pin which controls the frequency of oscillation. Can someone help!

Also I am thinking of using the output from this IC as clock input for EL16V IC for generating PECL compatible clock signal at 1.4 GHz.

Will it work?

What gave you the idea that Si530 is a VCXO? It says in the datasheet:

The Si530/531 IC based XO is factory configurable for a wide variety of user specifications including frequency, supply voltage, output format, and temperature stability. Specific configurations are factory programmed at time of shipment, thereby eliminating long lead times associated with custom oscillators.
