摘要:
A locked loop circuit is disclosed. The locked loop circuit includes phase detection circuitry to generate a first error output based on a phase difference between a first reference input and a locked-loop output. Summing circuitry receives the first error output and a second error signal. The second error signal is based on one from a selection of error values. Oscillator/delay circuitry generates the locked-loop output. For a first mode of operation, the second error signal is based on a first selected error value. For a second mode of operation, the second error signal is based on a second selected error value different than the first selected error value.
