Abstract
A controller includes a memory, a processor, and a first interface to a clock recovery unit that provides a recovered clock. When executed by the processor, instructions from the memory cause the controller to: instruct, via the first interface, the clock recovery unit at a first loop bandwidth to provide the recovered clock to a signal sampler; instruct, via the first interface, the clock recovery unit at a second loop bandwidth wider than the first loop bandwidth, to provide the recovered clock to the signal sampler; compare measurements from the signal sampler at the first loop bandwidth to measurements from the signal sampler at the second loop bandwidth; and instruct, via the first interface, the clock recovery unit at a third loop bandwidth to provide the recovered clock to the signal sampler applying adjustments based on comparing the measurements.
