Problem Statement. A very different way is needed to perform jitter testing of multi-Gbps physical layer ICs on a highvolume production line [1]. To perform high-volume production testing, several issues must be addressed. First, what measurements are required to characterize jitter in multi-Gbps physical layer ICs? Should the BER performance of the IC be tested or not? Secondly, as shown in Fi...

When a shared channel or packet switched network is used for transmission (e.g. WLAN, HSPA (Turbo-3G), LTE (4G)), it introduces variance in the delay of packets. This variance is called jitter. This jitter can lead to significant degradation of quality in real-time services if it is not properly handled. High Speed Packet Access (HSPA) is an extension to the third Generation W-CDMA cellular net...

Clock (CLK) generators and synthesizers form the pulse of a complex digital system and errors in a clock's signal quality can have wide-ranging effect. One of the most important performance measurements is clock jitter. Jitter is defined as "the short-term variation of a signal with respect to its ideal position in time." In a clock generator chip, there are many factors which contribute to out...

Noise is present in every system. Phase noise, in particular, is commonly found in oscillators and phaselocked loops can degrade the performance of a system. Phase noise in the oscillator of a wireless communication system degrades the receiver's sensitivity in reciprocal mixing conditions. Phase noise in a telecommunications system causes time jitter in the signal chain. Although engineers usu...

Jitter analysis is yet another field of engineering that is pock-marked with acronyms. Each category and type of jitter has its own acronym and every one of them gives insight into problems that limit the bit error ratio of a system. In this paper, we define the categories and types of jitter, their origins and interrelationships, and how they can be used to diagnose and debug system hardware. ...

There exist a Model of Proportional Jitter Differentiated Service and Proportional Delay Differentiated Serivce, which provides proportional jitter or proportional delay between different classes. This first approach is very appropriated for high-speed networks because it does not require the implementation of the proportional jitter scheduling algorithms at all the routers in the network but o...

We demonstrate the use of fiber Bragg grating based pulse-shaping technology to provide timing jitter tolerant data demultiplexing in an 80 Gb/s all-optical time division multiplexing (OTDM) system. Error-free demultiplexing operation is achieved with 6 ps timing jitter tolerance using superstructured fiber Bragg grating based 1.7 ps soliton to 10 ps rectangular pulse conversion at the switchin...

Performance Index: We evaluate phase noise of VCO as a performance index of frequency domain, and cycleto-cycle jitter and cycle-jitter, as performance indices of time domain. The cycle-jitter is estimated from the histogram of period (Ti) in oscillation waveform, and, the cycle-to-cycle jitter is estimated by histograming the difference in periods from one cycle to the next (Ti-Ti-1). The cycl...
