Companies showcase electrical PCIe compliance up to 64GT/s

Anritsu Corporation has announced that it has assisted AMD accelerate the testing of electrical compliance for PCIe specification for pre-production AMD EPYC CPUs. Achieving a maximum data rate of 64GT/s using the high-performance Anritsu BERT Signal Quality Analyzer-R MP1900A, testing was completed under challenging backchannel conditions with insertion loss exceeding the specified 27dB in the CEM specification, along with stress conditions applied using Spread Spectrum Clocking (SSC).

"In collaboration with Anritsu, we have achieved a stable demonstration of electrical compliance up to 64GT/s," said Amit Goel, corporate vice president, Server Engineering, AMD. "This early validation furthers our commitment to delivering reliable, high-speed I/O for future platforms powered by our next-generation AMD EPYCTM CPUs."

"AMD is a key technology partner in advancing PCIe technology," said Takeshi Shima, director, senior vice president, Test and Measurement Company President of Anritsu Corporation. "We will continue to respond to various test needs and expand functions for PCIe compliance testing, while also contributing to quality evaluation and design efficiency of PCIe devices through proposals to standards organisations."

PCIe 6.0 technology is the next-generation standard that provides a bandwidth of 64GT/s per lane and up to 256GB/s in a x16 configuration as a high-speed interface between internal devices such as CPUs, GPUs, SSDs, and network cards. While maintaining compatibility with previous standards, it achieves highly reliable and efficient communications in fields such as AI, HPC, and high-speed storage, significantly contributing to the improvement of next-generation data centres and analytical systems.
