Abstract
A frequency control unit has an input to receive a digital downstream strobe signal and an output to provide a controlled delay to the input strobe signal. A downstream latch has a data input to receive a digital downstream data signal and a clock input coupled to the output of the frequency control unit. The controlled delay is essentially equal to a set up time of the latch. A delay element coupled to the output of the frequency control unit further delays the downstream strobe signal by essentially a propagation time of the latch. Output drivers are coupled to the outputs of the latch and the delay element.
