Abstract
A time to digital converter is used to determine which edge of the higher frequency clock (oversampling clock) is farther away from the edge of the lower frequency timing signal. At the same time, the oversampling clock performs sampling of the timing signal by two registers: one on the rising edge and the other on the falling edge. Then, the register of 'better quality' retiming, as determined by the fractional phase detector decision, is selected to provide the retimed output.
