Low Phase Noise Series

Pure Reference Clocks for RF and Wireless Systems

FCom low-phase-noise OCXO, TCXO and VCXO solutions provide spectrally clean frequency references for radar, RF conversion, microwave communication and precision test equipment. Select by carrier frequency, phase noise at key offset frequencies, frequency stability, output format and tuning requirements.

Choose the Right Low-Noise Architecture

ULTRA-LOW-NOISE OCXO

FOC-5S-LN

−145 dBc/Hz @ 100 Hz

For radar and precision RF references.

STANDARD OCXO

FOC-2D / FOC-3D

−115 to −120 dBc/Hz @ 10 Hz

For telecom and test equipment.

LOW-NOISE TCXO

FVT-6S / FVT-2S

−115 dBc/Hz @ 100 Hz

For compact, temperature-stable RF systems.

TUNABLE VCXO

FVC-3X

Voltage-Controlled Reference

For PLL and clock synchronization.

Measured Under Defined Test Conditions

Phase-noise performance is characterized at defined carrier frequencies and offset points to verify spectral purity across the applicable product series.

*Production verification scope, phase-noise plots and additional test documentation are available according to product series and project requirements.

How Phase Noise Is Specified

A phase-noise value is meaningful only when its carrier frequency, offset frequency and measurement conditions are defined.

Spot Phase Noise

Offset Frequency

Carrier Frequency

Close-In and Far-Out Noise

Spurs and Noise Floor

Low Phase Noise Oscillator Portfolio

Compare OCXO, TCXO and VCXO solutions by carrier frequency, phase-noise performance at key offset frequencies, stability, output format and tuning capability. Refer to the individual datasheet for complete phase-noise plots and test conditions.
