Summary:A desynchronizer for extracting and desynchronizing a tributary signal from a multiplex signal at its original data rate has a buffer memory for temporarily storing tributary data bits extracted from the multiplex signal, an adjustable oscillator for generating a read clock for reading the tributary data bits or bytes from the buffer, and a comparator for comparing the read and write timing rates of the buffer memory in synchronism with the frame rate of the multiplex signal to generate a control signal to adjust the oscillator.
