PCIe® Test – Compliance and Debugging Solutions for Electrical (PHY) Layer, CXL® and NVMe™ Testing

CrossSync PHY for PCIe uses a single interposer that connects to a protocol analyzer and provides probe inputs to the oscilloscope. A single software interface unifies oscilloscope and protocol analyzer views.

• CrossSync PHY PCIe capable interposers enable observation of both electrical and protocol behavior without disturbing the link
• Sideband signals, reference clock and power rails are all easily accessible to oscilloscope probes
• High-bandwidth oscilloscope probing points for data lanes to debug during PCIe link training failure

CrossSync PHY for PCIe provides cross triggering between the protocol analyzer and the oscilloscope, and built-in software makes minor timing corrections. Therefore, all protocol and oscilloscope captures are time correlated, making it easy to resolve interoperability problems.

• Trigger protocol analyzer and oscilloscope captures on the same high-level event using the powerful triggering capabilities of the protocol analyzer.
• Easily measure timing relationships between protocol and electrical domains
• Faster root-cause analysis means fewer costly finger-pointing exercises
