Search for TCXOs

Ideal for precision demanding applications

Aside from offering outstanding performance and consistency with long-term, stable performance, tcxos have become the choice timing device for applications requiring unparalleled performance. Temperature controlled crystal oscillators can meet the standard for applications requiring less than 1PPM performance along with exceptionally low jitter (cycle to cycle) and TDEV or MTIE performance. These oscillators can provide an extremely stable output over temperature and is a less expensive alternative to the Oven Controlled Crystal Oscillator (OCXO).

Applications

TCXOs are well suited for the following communication, data-com and telecom applications requiring low power consumption and no warm -up period:

• High End Mobile Phones
• High End PDA/Smart Phones
• WLAN
• WiMax Applications
• GPS Applications (In-car Navigation, speed detection devices and security tracking systems)
• Other Base Station Applications

Demanding applications requiring such critical performance will find the features of a TCXO design superior over other timing device solutions.

How they function

Using a signal from a temperature sensor, these components generate a correct voltage that is applied to a voltage-variable reactance or varactor. A frequency is then produced by the varactor that is equal and opposite to the change in frequency produced by the temperature. These oscillators are not recommended when high stability over wide temperature ranges are required.

TCXOs are available in stabilities from ±0.5ppm to ±10ppm with electrical and/or mechanical tuning.
