WebWith this synthesizer we are able to achieve a jitter of only 50fs integrated from 10Hz to 2.5GHz offset at a carrier frequency of 75GHz. This is in part achieved by a very low in-band phase noise of −111.8dBc at 10kHz offset. The sta- bilizable frequency range is 62–88GHz. WebTools. In electronics and telecommunications, jitter is the deviation from true periodicity of a presumably periodic signal, often in relation to a reference clock signal. In clock recovery …

If we assume an ideal clock signal and compare it against the actual clock, then the jitter of the n th rising edge is the time deviation of the n th rising edge of the actual clock from the ideal clock. See Figure 1. Figure 1. Jitter definition.
