Analysis of jitter due to call-level fluctuations CWI's research has a theme-oriented structure and is grouped into four clusters. Listed below are the names of the clusters and in parentheses their acronyms. Analysis of jitter due to call-level fluctuations ABSTRACT In communication networks used by constant bit rate applications, call-level dynamics (i.e., entering and leaving calls) lead to ...

We transfer an optical frequency over 251 km of optical fiber with a residual instability of 6x10(-19) at 100 s. This instability and the associated timing jitter are limited fundamentally by the noise on the optical fiber and the link length. We give a simple expression for calculating the achievable instability and jitter over a fiber link. Transfer of optical stability over this long distanc...

As data rates increase, crosstalk becomes an increasingly important issue. Crosstalk aggressors can attack both amplitude and timing characteristics of the victim signal. The effects of crosstalk on the jitter of a victim signal are not well understood because crosstalk does not fit neatly into the standard definitions of jitter components. As a result, most commercially available jitter analyz...

We present comprehensive simultaneous studies of jitter process in time, frequency, and statistical domains. Math models for jitter characteristics and mapping relationships between one domain and the other are presented, along with the simulation experimental results. The theory and methodologies introduced in this paper enable better understanding, accurate implementing and correlating those ...

Thetiming jitter in relaxation oscillators is analyzed. This jitter is described by a single normalized equation whose solution allows prediction of noise in practical oscillators. The theory is confirmed by measurements on practical oscillators and is used to develop a prototype low noise oscillator with a measured jitter of 1.5 ppm rms.

approvedAs the functionality of digital chips continues to increase dramatically, chipto-chip communication bandwidths must scale accordingly to avoid constraining the overall system performance. Therefore, high speed transceiver design has become an important research topic. In particular, the performance of the circuits that are responsible for timing accuracy are important as bit periods con...

A stable passively synchronized femtosecond laser has been realized by coupling two 1.3 W mode-locked Ti:sapphire lasers with a Kerr medium. An ultralong tolerance of 10 microm for the cavity length mismatch and a timing jitter of less than 0.4 fs were obtained. The relative carrier-envelope phase slip was directly observed by measuring the heterodyne output between the two lasers.
