Jitter Limitations on a Gigabit Copper Multi- Carrier System
نویسندگان
چکیده
The feasibility of a multi-carrier system for data-transmission over copper wires at gigabit rates is analyzed. More specific, we look at the effects of jitter and duty-cycle deviations on the SNR and error rate using Matlab simulations. Jitter causes crosstalk between the inphase and quadrature channels of a given tone frequency. Given a certain rms jitter variance, low frequency tones can carry more bits than higher frequency tones for the same error rate. Duty-cycle deviations cause crosstalk both from other carrier frequencies and from quadrature channels. These problems seem so big that a PAM system is likely to be the better choice for gigabit transmission. Keywords— data-communication, jitter, multi-carrier modulation

Periodic Jitter Injection with Direct Time Synthesis by SPPTM ATE for SerDes Jitter Tolerance Test in Production
Controlled amount of jitter injection into high speed serial bit stream is required for SerDes jitter tolerance test. While jitter injection by Direct Time Synthesis can be a much more cost effective method than a combination of several instruments, it is not widely used yet. Considering its high potential in high volume production test cost reduction, we have studied the basics of the jitter i...
متن کاملThe effect of carrier phase jitter on MC-CDMA performance
In this paper, we investigate the influence of the carrier phase jitter of a phase-locked local oscillator on the performance of a multi-carrier code-division multipleaccess (MC-CDMA) system in a non-dispersive channel. This carrier phase jitter degrades the signal-to-noise ratio at the input of the decision device. When all users have the same power level and phase jitter spectrum, it is shown...
متن کاملDelay Spread and Time Delay Jitter for the Uhf Factory Multipath Channel
The results of wide band delay spread and time delay jitter measurements collected from five factory buildings are presented here. Carrier frequency was 1282 MHz. The data show that excess mean delay, r.m.s. delay spread, and time delay jitter values in single-story factory buildings are similar to values observed in and around multi-story office buildings. Differential time delay jitter measur...

A fully integrated phase-locked loop (PLL) fabricated in a 0.24 micrometer, 2.5v digital CMOS technology is described. The PLL is intended for use in multi-gigabit-per-second clock recovery circuits in fiber-optic communication chip. This PLL first time achieved a very large locking range measured to be from 30MHz up to 2GHz in 0.24 micrometer CMOS technology. Also it has very low peak-to-peak ...
