  • Jitter detection circuit
    Patent number: 7406145
    Abstract: There is provided a jitter detection circuit of a phase locked loop circuit, comprising a comparison circuit. The comparison circuit compares an input clock that is inputted to the phase locked loop circuit and an output clock that is outputted by the phase locked loop circuit. When it is determined that the frequency difference between the input clock and the output clock is outside a predetermined range, the comparison circuit outputs a first anomaly signal. The comparison circuit is constituted as a digital circuit.
    Type: Grant
