xtal frequency

Hi,

Is possible to vary Xtal frequency slightly by voltage?
Thanks
 

xtal change frequency

Yes. Xtal oscillators whose frequency can be controlled by voltage are called VCXOs (voltage controlled Xtal oscillators).
Usually varicap diodes are used for this purpose. See some link on this topic:

For small variations, a crystal oscillator with an external "pull" varicap diode is a usual technique. You can expect several 100 ppm maximum, sufficient to adjust an oscillator to it's nominal frequency in a small bandwidth PLL.
