Abstract
A network interface for use within a distributed antenna system, the network interface including circuitry configured to: receive a downlink digital communication signal from an external device external to the distributed antenna system, wherein a reference clock is embedded in the downlink digital communication signal; generate a master reference clock for the distributed antenna system using the reference clock embedded in the downlink digital communication signal; convert the downlink digital communication signal into a downlink signal; communicate the downlink signal toward a remote antenna unit within the distributed antenna system; and wherein the distributed antenna system is configured to distribute the master reference clock to various components of the distributed antenna system to keep the various components of the distributed antenna system locked to a single clock, wherein the various components of the distributed antenna system include the remote antenna unit.
