Anritsu plans PCI-Express 6.0 and 7.0 demos for PCI-SIG 2025

Anritsu will present PCI-Express 6.0 and 7.0 live demonstrations of the MP1900A BERT in collaboration with Synopsys, Teledyne LeCroy, CIG, and Tektronix.

Anritsu is joining forces with Synopsys, Tektronix, and CIG to demonstrate the world's first PCIe 6.0 optical connection link training using the Anritsu MP1900A BERT, Synopsys PCIe 6.x PHY and Controller IP, Tektronix DPO70000 Real Time Oscilloscope, and CIG OSFP LPO optical module.

PCIe over optical links provides higher bandwidth, covers longer distances, and is more energy-efficient, effectively addressing key bottlenecks for AI workloads in data centers.

In collaboration with Teledyne LeCroy, Anritsu will present a solution for evaluating the effect of differential skew in PCIe 7.0. PCIe 7.0 uses PAM4 signaling, which reduces eye height by more than three times compared to NRZ. Combined with the speed increase from 32.0 Gbaud in PCIe 6.0 to 64.0 Gbaud, this results in a smaller unit interval (UI) that is significantly more sensitive to skew.

In high-speed environments, signals traversing an ISI channel may exhibit a dip in the fundamental frequency due to skew.

While most BERTs lack built-in skew evaluation functions, Anritsu addresses this by using two MP1900A MU196020A PAM4 PPG units with the Channel Sync function to inject P-N skew and Teledyne LeCroy’s WaveMaster 8650HD 65 GHz oscilloscope for advanced analysis.
