Evolution of Various Crosstalk Metrics & Evaluation Methods for High Speed Serial Link & Their Complementary Characteristics

Masashi Shimanouchi (Design Engineer, Intel)

Hsinho Wu (Designer Engineer, Intel Corp.)

Mike Li (Fellow, Intel)

Location: Ballroom G

Date: Thursday, January 31

Time: 2:50pm - 3:30pm

Track: 09. Measurement, Simulation & Optimization of Jitter, Noise & Timing to Minimize Errors

Session Type: Technical Session

Vault Recording: TBD

Audience Level: All

Many factors degrade high speed serial link performance, and crosstalk is one of the major culprits. First, we review the evolution of the crosstalk metrics and evaluation methods for Ethernet and CEI such as ICR, ICN and COM. Then, we elucidate the conditions where random noise can be justifiably used to emulate crosstalk by studying the relationship among crosstalk noise pdf, data rate, signal / crosstalk phase relation, and PAM-n dependency. This is essential since receiver interference tolerance test for Ethernet uses random noise instead of physical crosstalk. We also discuss the bounded nature of random noise.

Takeaway

First, the evolution of the crosstalk metrics and evaluation methods for Ethernet and CEI is reviewed. Then, the conditions where random noise can be justifiably used to emulate crosstalk is elucidated by studying the relationship among crosstalk noise pdf, data rate, signal / crosstalk phase relation, and PAM-n dependency.
