Data jitter measurement using a delta-time-to-voltage converter method

This paper demonstrates a new low cost method for data jitter measurement. It shows that jitter in data steam can be accurately measured in real time by combining an interpolated data sequence with a delta-time-to-voltage converter. Experimental results using a 2.5-Gbps PRBS with injected sinusoidal jitter and DDJ are presented to illustrate the usefulness and accuracy of this method.
