Jitter Analysis
The jitter analysis function is mainly used to analyze the integrity of the high-speed
serial signal and measure the variance of a measurement over time. The
measurement item includes TIE, Cycle to Cycle, +Width to +Width, and –Width to
-Width. Wherein, TIE indicates time interval error. The TIE measurement compares
the edges in a data signal with the edges in an ideal data signal determined by the
clock recovery feature to generate error statistics.
