Method and apparatus for efficiently transmitting multiple data signals
A switch suitable for use in high-bandwidth environments is disclosed. The switch eliminates the need for inter-stage jitter compensation by determining the timing signals associated with each data input and then re-timing the data based upon the timing signals at the switch output. Bandwidth is conserved by routing timing signals through a multiplexer that preferably determines the difference between the timing signal and a reference signal, combines the difference signal with other difference signals calculated for other data inputs, and then transmits the multiplexed difference signals to a demultiplexer. Suitable multiplexing schemes include time division multiplexing, wavelength division multiplexing, code division multiple access (CDMA) multiplexing, as well as various combinations of suitable multiplexing methods.
