Precision latency control

A system and method for serializing output includes shift registers that sample a deserialized input signal at a relatively slow clock speed. Data latency between the input and output signals is controllable to a higher granularity than the input signal with bit positions corresponding to the high-speed input signal. A predictive learning algorithm receives data latency values from the input signal and corresponding data latency values from the output signal to correct and control output latency, potentially within one high speed clock cycle.
