Testing PCI Express 5.0 PHY Receiver Performance in the Absence of a Controller White Paper

The “Testing PCI Express® 5.0 PHY Receiver Performance in the Absence of a Controller” white paper explains how receiver electrical validation can be performed without relying on MAC‑level link negotiation. At 32 GT/s, traditional automated test suites often require a fully integrated system to establish linkup before testing can begin. This paper presents an alternative approach that enables early, controller‑independent receiver characterization, accelerating PHY development and silicon validation.

What You Will Learn:

• Why negotiated linkup complicates early receiver testing
• How receiver jitter tolerance can be evaluated without a controller
• How stressed‑eye calibration enables accurate standalone testing
• How early PHY validation accelerates development schedules
