Seamless Transition to PCIe® 5.0 Technology in System Implementations

December 2, 2020 by AsteraAdmin

In this PCI-SIG® hosted technical webinar, Astera Labs’ engineers explore the changes between PCIe 4.0 and PCIe 5.0 specifications, including signal integrity and system design challenges, where the right balance must be found between PCB materials, connector types and the use of signal conditioning devices for practical compute topologies. Through an objective analysis, the goal is to provide the audience with a methodology to optimize signal and link integrity performance, present best practices for system board design to support PCIe 5.0 technology applications, and test for system level interoperation.

PCI Express® 5.0 Architecture Channel Insertion Loss Budget

June 11, 2020 by AsteraAdmin

The upgrade from PCIe 4.0 to PCIe 5.0 doubles the bandwidth from 16GT/s to 32GT/s but also suffers greater attenuation per unit distance, despite the PCIe 5.0 specification increasing the total insertion loss budget to 36dB. After deducting the loss budget for CPU package, AIC, and CEM connector, merely 16dB system board budget remains. Within the remaining budget, engineers need to consider safety margin for board loss variations due to temperature and humidity.

Simulating with Retimers for PCIe 5.0

March 16, 2020 by Casey Morrison

retimer-cxl

The design solution space for high-speed serial links is becoming increasingly complex with increasing data rates, diverse channel topologies, and tuning parameters for active components. PCI Express® 5.0, at 32 GT/s, is a particularly relevant example of an application whose design solution space can be a daunting problem to tackle, given the performance-cost requirements of its end equipment. This paper is intended to help system designers navigate these design challenges by providing a how-to guide for defining, executing, and analyzing system-level simulations, including PCIe 5.0 Root Complex (RC), Retimer, and End Point (EP).

In this video, Casey Morrison gives a quick tutorial on PCIe® Retimers – What do they do? When to use them? What key features to look for? PCI-SIG compliance requirements, etc.

Signal-integrity challenges will be significant in PCIe Gen 4.0 and Gen 5.0 due to increased data rates. A PCIe Retimer is a cost-optimized option to provide more margins and enable a robust link. Compliance tests meeting electrical and protocol specifications, latency, small total footprint, power consumption, bifurcation capacity, in-band and side-band diagnostics are key features system designers should look for in Retimers.
