Abstract
A system delays input clock signals using time-to-digital converters (TDCs) to convert edges or the clock signals to digital values and storing the digital values in a memory. The digital values are retrieved from the memory based on a desired delay. A time counter used by the TDCs to determine the edges is also used determine the delay. The accuracy and range of the delay depends on the time counter and size of the memory.
