Temperature Compensated Crystal Oscillators (TCXOs & VCTCXOs)

START 'TCXO & VCTCXO' PRODUCT SEARCH

Temperature Compensated Crystal Oscillators (TCXO) deliver excellent temperature characteristics combined with low power consumption and fast warmup. Voltage Controlled Temperature Compensated Crystal Oscillators (VCTCXO) 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 and later, 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 VCTCXOs are used where the stability of a standard Crystal Clock Oscillator is insufficient. IQD's wide range of TCXO and VCTCXO models offer tight frequency temperature stability performance down to the 'parts per billion' (ppb) level of many low end Oven Controlled Crystal Oscillators (OCXOs). With much smaller package sizes, low power consumption and significantly lower cost, IQD's TCXO and VCTCXO models provide a viable alternative to many traditional OCXO applications. Some of our TCXO models incorporate an analogue ASIC which provides a smoother signal when combined with a high order temperature compensation circuit.

As a previous division of Rakon, IQD maintains a close partnership as a worldwide channel partner supplying Rakon’s wide range of high stability Temperature Compensated Crystal Oscillator (TCXO) solutions, from highly stable products for mass volume consumer applications through to industry leading ultra-stable products for more demanding applications. Rakon's commitment to quality and high performance has meant it has become the default standard for consumer GPS, emergency beacons, telecommunications infrastructure and many other performance critical applications.

Our TCXO and VCTCXO range covers virtually all applications within the electronics industry with package sizes down to 2.0 x 1.6mm. We also offer a custom TCXO design and application service to meet specific customer requirements where characteristics such as frequency slope and perturbation specifications can be customised to satisfy specific applications.
