Introduction to Custom Oscillators

For applications where a compact, low power and high stability frequency source is required, Hy-Q supply a comprehensive range of Through Hole crystal oscillators. The standard range discussed here cover the frequency range of 1 Hz to 40 MHz and are available in a wide range of package styles and sizes to suite our customers applications. Frequencies higher than these are detailed in our High Frequency Oscillator range.

Frequency stability over a temperature band is often the most important parameter to specify. Where this is not critical a Simple Packaged Crystal Oscillator (SPXO) will be the cost effective option. However, where tight stability is needed then a Temperature Compensated Crystal Oscillator (TCXO) will be required.

There are also many applications where adjustment of oscillation frequency is necessary, whether internally by means of a trimmer capacitor, or externally by application of a control voltage (VCXO). Where voltage control is applied to a TCXO the term VCTCXO is used. Examples of these are within the Hy-Q standard product range.

Should you require an oscillator with criteria outside the standard range then Hy-Q are happy to customise a product to meet your needs. As with all our other products, we recommend you contact our Sales Department for help with your application.
