TCXO oscillators (Temperature Compensated Crystal Oscillator) are oscillator units with a tight frequency offset over a certain temperature range. Typical TCXO applications can be found in areas where a stable frequency is needed in an environment with changing temperatures. In a TCXO the frequency change over temperature of the crystal is compensated by an internal circuit. This TCXO temperature controlled circuit can be analog but also digital. Digital compensated TCXO units are ‘programmed’ with the frequency offset characteristics. For the output signal there are several options. The CMOS TCXO and Clipped Sine Wave TCXO are most common but we have options for other output levels like True Sine Wave TCXO types. Optional, several types can be supplied with EFC (Electronic Frequency Control). These VCTCXO oscillator (Voltage Controlled TCXO) types can be adjusted in frequency by a control voltage. Package types are from small 4 pad SMD TCXO units to through hole DIL14 TCXO housing.
Below is a general overview of the various types used for most TCXO applications. If you need support, contact us by email or contact form.
