Vitesse Semiconductor Corp., LeCroy Corp. and Wild River Technology presented a jointly prepared paper titled “A Robust method for Addressing 12Gbpsec Interoperability for High-Loss and Crosstalk Aggressed Channels,” at DesignCon 2012 at the Santa Clara Convention Center in Santa Clara, Calif., on Tuesday, January 31, 2012.
During the session, engineers involved with signal integrity design and backplane characterization with system interoperability issues related to crosstalk and channel loss learned about a new methodology, which was demonstrated on 10.7 Gbps measured systems. It involved synthesizing a perfect SerDes architecture, simulating responses with a host of pathological channels using S-parameter models, and then performing a final co-verification using internal eye monitoring metrics.
“As data rates increase, high speed serial channels are stressed by more than just excessive losses,” said Eric Bogatin, president of Bogatin Enterprises. “They are also stressed by channel-to-channel cross talk. The challenge is integrating cross talk pathology into serial link analysis.”
The paper was co-authored by James Bell and Al Neves of Wild River Technology, Alan Blankman from LeCroy Corp., Eric Bogatin, founder of Bogatin Enterprises, and Martin Spadaro and George Noh of Vitesse.
