Jitter is, as shown in Figure 1, is “the short-term variations of a signal with respect to its ideal position in time.” Figure 1. Jitter in Clock Signals This deviation in a clock’s output transition from its ideal position can negatively impact data transmission quality. In many cases...
Tangible non-transitory computer-readable storage devices can contain instructions that when carried out on processor(s) carry out the above process An apparatus has a clock sampling unit and a signal analyzer to derive the measure of jitter. This abstract is not to be considered limiting, since...
host for unbuffered/small outline modules or clock driver for clock driver unbuffered/small outline modules. Because the clock is measured within a system a high impedance, a solder-in probe is used to capture the clock signal. It’s important to measure as close as possible to...
Settling timeis the amount of time for a signal to reach a certain accuracy and stay within that range. Hysteresisprovides an amount of immunity to high-frequency noise in your digital system. Skewis when the clock signal arrives at different components at different times. ...
The clock mask masks clock signals corresponding to overhead bytes among the received clock signals. The N-phase clock generator divides the period of the output clock signal of the clock mask by N, to generate N-phase clock signals. The read clock generator sequentially selects the N-phase ...
System for digital cancellation of clock jitter induced noise in a gyroscope with provides better power effect In a digital gyroscope, the rate signal (including the quadrature) and the displacement signal of the drive part are sampled with an ADC. This displacement signal has the same frequency ...
Figure 4 shows a clock signal illustrating the concept of accumulated jitter. Accumulated jitter is the accumulation of the period jitter over many cycles. In real systems, we only need to consider the jitter over specific bandwidths, so the accumulated jitter will reach a limit independent of ...
clock to up-convert or down-convert, the resulting spectrum becomes the multiplication of the spectrum of the signal with the spectrum of the clock. Any phase noise in the clock signal will result in an undesired signal at the output, reducing the signal to noise ratio (SNR) of the system...

The SC(f) curve results when we connect the clock signal to a spectrum analyzer. The phase-noise spectrum L(f) is then defined as the attenuation in dB from the peak value of SC(f) at the clock frequency, fC, to a value of SC(f) at f. Figure 3 illustrates the definition of L...
