Anritsu and AMD Demonstrate PCI Express Compliance at 64 GT/s

Anritsu Corporation has announced that it has supported AMD in accelerating electrical compliance testing for PCI Express (PCIe) on pre-production AMD EPYC CPUs.

Using the high-performance Anritsu MP1900A BERT Signal Quality Analyzer-R, PCI Express testing reached a maximum data rate of 64 GT/s under challenging backchannel conditions with insertion loss exceeding the 27 dB specified in the CEM standard and stress conditions from Spread Spectrum Clocking (SSC).

“In collaboration with Anritsu, we achieved stable electrical compliance up to 64 GT/s,” said Amit Goel, Corporate Vice President, Server Engineering, AMD. “This early PCI Express validation supports our commitment to delivering reliable, high-speed I/O for next-generation AMD EPYC™ platforms.”

“AMD is a key partner in advancing PCI Express technology,” stated Takeshi Shima, President of Anritsu’s Test and Measurement Company. “We will continue meeting diverse test needs, expanding PCIe compliance testing functions, and contributing to quality evaluation and design efficiency through standards proposals.”

PCIe 6.0 technology is the next-generation standard that provides a bandwidth of 64 GT/s per lane and up to 256 GB/s in a x16 configuration as a high-speed interface between internal devices such as CPUs, GPUs, SSDs, and network cards. Maintaining backwards compatibility, it enables reliable, efficient communication for AI, HPC, and high-speed storage, enhancing next-generation data centre and analytics performance.
