Our range of voltage controlled temperature compensated crystal oscillators adds the utility of voltage control to the benefits of temperature compensation in crystal oscillators.
What is a voltage controlled temperature compensated crystal oscillator?
Temperature Compensated Crystal Oscillators (TCXOs) deliver excellent temperature characteristics combined with low power consumption and fast warmup. Voltage Controlled Temperature Compensated Crystal Oscillators (VC-TCXOs) combine the same excellent temperature characteristics, low power consumption and fast warmup with a voltage control function to allow precise tuning of the output frequency after PCB assembly.
Voltage control can also be used during operational life, to compensate for any effects of aging as well as offering the ability to pull back to nominal frequency where there is a change of circuit conditions. TCXOs and VC-TCXOs are used where the stability of a standard Crystal Clock Oscillator is insufficient.
IQD’s IQXT-210 series of TCVCXOs offers frequency stabilities down to ±0.14ppm over the full industrial temperature range of -40 to +85 degrees C. These products approach Oven Controlled Crystal Oscillator (OCXO) performance levels, whilst being packaged in a miniature 8-pad 5 x 3.2mm package.
The IQXT-210 is primarily designed for low power consumption applications such as Femtocells, Smart Wireless Devices, Fibre Optic Networking (PON), Microwave Satellite Communications, LTE/4G Base Stations, Backhaul Infrastructure, Packet Transport Network (PTN) Computer Networking, RF Modules, Wi-Fi plus Test & Measurement Equipment.
Bliley TC-VCXOs (VC-TCXOs) are capable of meeting frequency vs. temperature stabilities which rival traditional OCXO technology. This coupled with design topologies meeting the harshest Mil-Standards makes Bliley TCXOs the choice of many system designers for mobile equipment.
