Temperature Compensated Crystal Oscillators (TCXO)

Temperature Compensated Crystal Oscillators use compensation circuitry to reduce crystal frequency drift over temperature. They provide compact reference timing where oven control is not required.

TCXO crystal oscillator for temperature compensated RF timing

FAQ

How should frequency accuracy, temperature stability, aging and holdover be specified?

Specify accuracy, temperature, aging and holdover as separate error terms with their own interval, environment, warm-up and reference history instead of one unexplained ppm value.

Temperature Compensated Crystal Oscillators (TCXO)

A TCXO applies temperature compensation to a crystal oscillator so the reference frequency remains controlled across changing ambient conditions. It is a compact timing source for equipment that does not need an ovenized reference.

System role

TCXOs are used in RF modules, GNSS and satellite terminals, communication equipment, portable instruments and synchronized platforms where size, power and temperature behavior are linked.

Data to confirm

Useful records include nominal frequency, stability over temperature, aging, phase noise, output format, supply voltage, current, startup time, load condition and operating temperature.
