Hy-Q International supplies a range of standard oscillators covering a frequency range of 1Hz to 175MHz.
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 most cost-effective option, but where high stability is needed 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. Hy-Q standard product range includes this kind of device.
The company can also provide custom oscillators for customers whose requirements lie outside the standard range.
