A method of serial data jitter analysis using one-shot time interval measurements
J.B. Wilstrup · 2002
A method for measuring inter-symbol interference, duty cycle distortion, random jitter and periodic jitter is described. The Blackman-Tukey method of signal analysis is used. This allows the application of jitter tolerance masks to ensure compliance to data communication standards. Mathematical analysis and computer simulations have been performed. The autocorrelation function and an FFT for clock jitter analysis have been implemented on our current product. A provisional patent application has been filed.
