Abstract
For re-timing sampled data, input data samples at an input data rate are stored in a FIFO buffer and output at an output data rate according to an output clock that is locked to the input data rate in dependence on a loop-filtered measure of the fill level of the said buffer. The frequency of the output clock is additionally controlled by an estimate of the input data rate.
