This calculator converts singlesideband phase noise into phase jitter. It is ideal for limited data sets (up to 20 segments), for example, as found in datasheets, or derived from piecewise linear approximations of actual phasenoise plots graphed on a loglog scale. Larger data sets, such as raw data output from test equipment, are more appropriate for a spreadsheetbased converter, which is discussed in an article found here. Avoid including spurs in the phase noise data if you intend to use the integrated RMS phase jitter value to estimate BER numbers.
Enter offset frequencies in order from lowest to highest below. Enter numbers below as integers, decimals, or use scientific notation (for example, enter 1500 as 1500, 1.5e3, or 1.5E3). Select the desired data by checking the appropriate box; the calculation will include data up to the first unchecked Enable Data box.
The carrier frequency must be below 1E12 Hz, the offset frequency is limited to 100GHz, and the phase noise must fall in the range of 0 to 200 dBc/Hz.
