Patent attributes
An apparatus may include a sampling circuit configured to produce a sequence of input samples based on a continuous time input signal and a sample clock signal, the sampling phase of the sequence of input samples based on a phase control value output by a timing recovery circuit. In addition, the apparatus may include the timing recovery circuit configured to receive the sequence of input samples, detect, for a current sample of the sequence of input samples, a phase offset in the sampling phase of the sequence of input samples, the phase offset being a deviation of the sampling phase from an expected phase, and in response to detecting the phase offset, select a bandwidth for timing recovery. Further, the timing recovery circuit may generate an updated phase control value based on the selected bandwidth for timing recovery.
