摘要: A system configured to generate a signal with a random or pseudo-random frequency may include an oscillator and a signal generator. The oscillator may be configured to generate an oscillator signal. A frequency and a phase of the oscillator signal may be random or pseudo-random and may be based on a value of a received control signal. The signal generator may be configured to generate the control signal based on the oscillator signal and a seed state. The value of the control signal may be random or pseudo-random.

摘要: A clock multiplication and distribution system includes a first phase-lock-loop circuit, a second phase-lock-loop circuit, and a clock distribution network that electrically couples the first phase-lock-loop circuit and the second phase-lock-loop circuit. The first phase-lock-loop circuit may include a first feedback loop that includes a first integer divider circuit and may be configured to generate a first clock using a reference clock. A frequency of the first clock may be greater than a frequency of the reference clock. The second phase-lock-loop circuit may include a second feedback loop that includes a second integer divider circuit and may be configured to generate a second clock using the first clock. A frequency of the second clock may be greater than the frequency of the first clock.

摘要: A circuit may include a signal converter configured to convert a differential signal to a single-ended signal. The circuit may also include a biasing circuit configured to set a bias of the signal converter based on a feedback of the single-ended signal such that a voltage level of the single-ended signal is at a target voltage level.
