Abstract
A digital data transport system where a serial stream of digital input data, received from a remote transmitter at an original clock frequency F,, enters a FIFO repository at a variable frequency bit rate having an average frequency rate of I,. A difference generator G, operating at the I,frequency rate, receives a first feedback frequency clock signal F,from a voltage controlled oscillator and a second feedback signal designating the current loading of the FIFO to provide a variable pulse stream to a driver whose output voltage controls the voltage controlled oscillator output frequency F,so that it will match the average input frequency bit rate I,(less the header bytes) in order to approximate the original clock frequency F,.
