EXPLOITING SHORTEST PATH FOR IMPROVED NETWORK CLOCK DISTRIBUTION

摘要

It identifies short route, takes precedence over the delay transmission or the delay picture of the identical signal and, it offers the device and the method of utilizing the existence of short route with the transmission original (102) device and the intended (104) device by using the signal which takes short route, it improves the dispersion of the signal with that. This invention PLL from the signal which takes short route the phase detector (302) of the phase synchronous loop which mainly it selects drives offers the processor with the low-pass filters (304). In one execution form, the processor includes scaler such as the exponential scaler which offers the asymmetrically error weight attaching in order to improve the dispersion of the signal which accompanies small delay (shortly route).
