What is said to be the world’s first PCI Express (PCIe) 5.0 Rx LEQ Test System supporting compliance test items is being demonstrated by Anritsu and Synopsys at DesignCon 2020 in Santa Clara (January 28-30). The solution uses Anritsu’s Signal Quality Analyser-R MP1900a series PCI Express 5.0 test system and Synopsys’ DesignWare IP for PCIe.

With high-speed data rates of 32 GT/s, PCIe 5.0 requires new measurements, such as complex link training and crosstalk tests.

With high-quality signals supporting 32G, the MP1900A PCIe solution improves the efficiency of link training tests by monitoring/logging Link Training and Status State Machine (LTSSM) transitions and generating event triggers for waveform capture.

Multichannel expandability for crosstalk tests and easy expandability from PCIe 4.0 (16 GT/s data rates) to PCIe 5.0 (32 GT/s data rates) support early implementation of PCIe 5.0 products.

The joint DesignCon 2020 exhibit will demonstrate stress signal generation using the MP1900A BERT and a PCIe 5.0 compliance board.

It will also conduct actual link training of a system incorporating the Synopsys DesignWare IP for PCIe 5.0 and Anritsu MP1900A PCIe 5.0 Link Training Software to evaluate receiver stressed input characteristics.
