Phase Noise (dBc/Hz) to Phase Jitter Converter

A linear characteristics between the data points is assumed. The data shown here is from an Mini Circuits ROS-1310C+ Oscillator. This is just for illustration. Feel free to insert your own values. The calculations are based on the paper of Bar-Giora Goldberg, "The Effects of Clock Jitter on Data Conversion Devices," RF Design, August 2002, pp. 26-32, available at http://www.rfdesign.com

Clock Freq.
Offset #1	Level #1	dBc
Offset #2	Level #2	dBc
Offset #3	Level #3	dBc
Offset #4	Level #4	dBc

Jitter [rms]		ms µs ns ps fs as
SNR		dB

✈ Notes

• In case you have more values, use the Excel Spreadsheet.
• To compare values, one usually limits the bandwidth to 10 kHz - 10 MHz. (12 kHz - 20 MHz)
• When displaying jitter values, always note the center frequency and the bandwidth !
