ABSTRACT:
A communication system which eliminates cumulative jitter is comprised of a transmitter which receives a continuous input stream of data bits at a transmitter input bit rate on an input port, and which simultaneously transmits the data bits in spaced-apart bit-serial data blocks with respective bit-serial headers that have a variable length and fill the space between the data blocks. Also, the communication system includes a receiver, coupled to the transmitter, which receives the spaced-apart data blocks, and which simultaneously generates from selected bits in the received data blocks but not the headers, an output stream of the data bits at a receiver output bit rate on an output port. Further the receiver includes a closed loop feedback control circuit which forces the output stream of data bits to be continuous and forces the receiver output bit rate to be substantially constant by maintaining a count of the number of data bits generated when the selected bits in the data blocks are not being received, minus the difference between the number of data bits received and generated when the selected bits in the data blocks are being received, within a predetermined range.
