Low-Jitter Oscillators for High-Speed Signal Integrity

FCom low-jitter XO, TCXO and VCXO solutions provide clean reference clocks for high-speed serial links, optical modules, data-center networking and telecom systems. Select by RMS phase jitter, integration bandwidth, output logic, frequency and operating temperature.

Choose the Right Clock Architecture

Ultra-Low-Jitter Differential XO

Clean differential reference clocks for applications with the tightest jitter budgets.

Down to 50 fs RMS

Standard Differential XO

Balanced jitter, interface flexibility and package options for high-speed digital clock distribution.

Down to 150 fs RMS

Low-Jitter CMOS XO

Solutions for processors, controllers and digital systems that do not require differential signaling.

Down to 0.6 ps RMS

Compensated & Tunable Clocks

Clocks for systems that require frequency stability or tuning in addition to low timing noise.

TCXO and VCXO Options

Measured Under Defined Test Conditions

Low-jitter performance is evaluated through phase-noise measurement and integrated RMS phase-jitter analysis under defined carrier-frequency and offset-range conditions.

*Production verification and test documentation are available according to product series and project requirements.

Jitter Is More Than One Number

A jitter value is meaningful only when the measurement method and test conditions are defined.
