Abstract
This application is directed to controlling bandwidths of clock recovery circuit in an electronic device. The electronic device includes a clock recovery circuit and a bandwidth controller coupled to the clock recovery circuit. The clock recovery circuit is configured to receive a data signal carrying a stream of data bits according to a reference clock frequency and recover a clock signal from the data signal. The bandwidth controller is configured to control the clock recovery circuit to start with a pull-in bandwidth, settle at a target bandwidth, and apply an intermediate bandwidth between the pull-in bandwidth and target bandwidth. The intermediate bandwidth is greater than the target bandwidth and less than the pull-in bandwidth. In some implementations, the bandwidth controller controls the clock recovery circuit to apply one or more additional bandwidths to the clock signal after the pull-in bandwidth and the intermediate bandwidth and before the target bandwidth.
