摘要:
A technique provides data from an information signal. The technique involves receiving the information signal in the forwarded clock device synchronously with a forwarded clock signal. The technique further involves recovering data contained within the information signal synchronously with a recovery clock signal such that the data is recovered with (i) a particular cycle latency when the recovery clock signal has an optimal rate for the forwarded clock device, and (ii) a different cycle latency when the recovery clock signal has a sub-optimal rate. The particular cycle latency may include more cycles than the different cycle latency. As such, the time latency may be shorter when the recovery clock signal has the sub-optimal rate.
