چکیده
Absiract -FIR fnter pre-emphasis has been used to Counteract inter-symbol interference @I) in highspeed backplane data transmission. In this paper, baclqlane channel characteristics are f i s t analyzed. It is round that channel group delay distortion is also n major IS1 contributor in addition to amplitude attenuation. AMATLAB program is then described for optimization of FIR filter under LMS criterion. Both symbol-spaced FIR (SSF) and fractionally-spaced FIR (TSF) arc comparatively studied at m e r e n t data rater. The determlnatlon of tap number and preference olFSF to SSF are discussed.

Studies on FIR Filter Pre-Emphasis for High-Speed Backplane Data Transmission
FIR filter-based transmitter pre-emphasis has been used to counteract inter-symbol interference (ISI) in high-speed backplane data transmission. In this paper, backplane channel characteristics are analyzed in both time and frequency domains. The analysis performed demonstrates that group delay distortion is a major ISI contributor in addition to amplitude attenuation. A Matlab program is then ...
متن کاملDesign Advances in PCB/Backplane Interconnects for the Propagation of High Speed Gb/s Digital Signals
Over the past five years tremendous advances have been made in the design of copper-based transmission line interconnects capable of propagating high-speed broadband digital signals over long lengths of printed circuit boards (PCBs) and backplanes. Data rates of 5 Gb/s transmitted over a single differential pair routed across more than one meter of PCB and backplane interconnect using low-cost ...
متن کاملTransmitter and Receiver Circuits for Serial Data Transmission over Lossy Copper Channels for 10 Gb/s in 0.13 μm CMOS
This paper presents a transmitter and receiver for high speed serial data links including pre-distortion and equalization circuits. The circuits allow data transmission over lossy copper channels up to 10 Gb/s and beyond. The transmitter uses a three tap FIR-filter for pre-distortion. A full rate FIR design allows a low latency and provides a smooth filter characteristic. An analog equalizer in...

The ever growing volume of backplane communications pushes the data rate toward 20Gb/s for the next-generation transceivers. Over the years, chip designers have been seeking different data formats to overcome the loss of electrical channels. Among the existing solutions, duobinary signaling manifests itself in bandwidth efficiency as (1) its spectrum occupies only half as wide as that of NRZ da...
متن کاملPower-efficient FIR filter architecture design for wireless embedded system
This paper presents a novel approach for implementing power-efficient finite-impulse response (FIR) filters that requires less power consumption than traditional FIR filter implementation in wireless embedded systems. The proposed schemes can be adopted in the direct form FIR filter and achieve a large amount of reduction in the power consumption. By using a combination of proposed methods, bal...
