Abstract

Return-to-zero (RZ) formatted data is recovered and transmitted using non-return-to-zero (NRZ) devices. A NRZ clock and data recovery device (CDR) interprets the clock rate of a RZ formatted signal as twice its actual clock rate. Due to this interpretation, extra zeroes will be inserted in the data stream. The extra zeroes introduced by the NRZ interpretation of the data are discarded, and the interpreted clock rate is divided resulting in preserving the values of the original data stream of the RZ formatted signal. A NRZ encoded data stream at a specific clock rate is processed so that when the data stream is transmitted to a recipient expecting RZ formatted data, the recipient interprets the correct data.
