VCXO CRYSTAL SELECTION
Choosing a crystal with the correct characteristics is one of the
most critical steps in using a Voltage Controlled Crystal Oscillator
(VCXO). The crystal parameters affect the tuning range and
V
C
Control voltage used to tune frequency
C
V
Varactor capacitance, varies due to the change in
control voltage
accuracy of a VCXO. Below are the key variables and an example
of using the crystal parameters to calculate the tuning range of
the VCXO.

Load tuning capacitance used for fine tuning or
centering nominal frequency

S1, CS2
Stray Capacitance caused by pads, vias, and other
board parasitics
