Abstract

For 40 Gb/s data transmission through electrical backplane trace up to 40 inch length on four layer fire-resistant (FR-4), we have designed the 40 Gb/s backplane channel model consisting of four channel 10 Gb/s. Simulation results show an enhancement of backplane channel characteristics excellent more than requirements specified in IEEE P802.3ba at 10 Gb/s. This paper provides a review of the structures and algorithms used in receive and adaptive equalization for 40 Gb/s backplane Ethernet. The use of this backplane channel model could achieves better receive equalizer at great data rate than 10 Gb/s.

본 논문에서는 40 인치 까지의 FR-4 백플레인 트레이스를 통해 40 Gb/s 데이터 전송을 위해서 10 Gb/s 4 래 인으 로 구성되는 백플레인 채널 모델을 설계하였다. 시뮬레이션 결과에서 10 Gb/s 데이터 속도에서 IEEE P 802.3ba 표준에서 규정하는 요구사항보다 더 나은 백플레인 채널 특성을 확인하였다. 본 논문에서 제시한 유형의 전송채널에 대한 연구를 수행하여야 40 Gb/s 백플레인 이더넷 수신 적응 등화기 등의 설계가 가능할 것이다.
