For the first time, PCI Express allows Refclk jitter compliance to be measured using a phase noise analyzer (PNA), as an alternative to the traditional real-time oscilloscope measurement. This talk discusses changes in the latest PCIe BASE Rev. 5.0 specifications for determining Refclk jitter compliance, impacting all data rates (GEN 1 through GEN 5). We’ll discuss the motivation for adding a compliance methodology based on phase noise, the pros and cons of phase noise versus oscilloscope methods, and clarify changes to the compliance load board. The new PNA methodology will be discussed in detail, including an exhaustive case study comparing PNA and oscilloscope compliance results spanning multiple clock devices from different clock vendors, and multiple test equipment manufacturers. Attendees will walk away with a complete understanding of how to show compliance for Refclk jitter.
