Abstract:
Aspects of the present disclosure provide for a method. In some examples, the method includes receiving a synchronization signal, dividing the synchronization signal to form a first divided signal and a second divided signal, generating a first ramp signal and a second ramp signal, setting a latch output to a logical high value when the first divided signal has a logical high value or a value of the first ramp signal exceeds a value of a reference signal, setting the latch output to a logical low value when the second divided signal has a logical high value or a value of the second ramp signal exceeds the value of the reference signal, generating a synchronization clock according to the latch output and an inverse of the latch output, and outputting the latch output or the synchronization clock as a clock signal based on a value of a synchronization active signal.
