ABSTRACT:
An integrated circuit includes a phase step generator and a clock circuit. The phase step generator generates an input clock signal based on a reference clock and the clock circuit generates an output clock signal based on the input clock signal. Additionally, the clock circuit generates a feedback clock signal based on the output clock signal and locks a phase of the feedback clock signal with a phase of the input clock signal. In response to an assertion of a trigger signal, the phase step generator extends a phase of the input clock signal by inserting a phase step into the reference clock signal. A bandwidth of the clock circuit is determined based on the output clock signal after assertion of the trigger signal.
