Title: Accurate and Low-Cost Deterministic Jitter Decomposition for High Speed Link

Abstract: Jitter performance plays a crucial role in Bit-Error Rate of High-speed digital communication system., jitter decomposition is a key tool to accurately derive each type of jitter as well as total jitter in a system and for identifying the root causes of jitter. In this paper, we propose a jitter decomposition algorithm using least squares (LS).It is designed to simultaneously separate three different jitters (Inter-symbol interference (ISI), Random Jitter (RJ) and Periodic Jitter (PJ)). The algorithm includes a new time domain ISI model which is based on channel pulse response more effectively rather than a conventional cursor convolution technique. The proposed jitter decomposition method is able to obtain the final estimated value with good accuracy by using fewer samples of total jitter data compared with conventional methods. The comparison between the   simulation and hardware experiment demonstrate the accuracy of the proposed method.
