Cable Extender Cards

Requirements & Challenges

• Cable, connector, and total board losses on both sides of the link make retiming a requirement for PCIe® 4.0 and PCIe 5.0 implementations
• SRIS/SRNS topologies are preferred because providing copies of REFCLK across each cable adds EMI challenges and additional cost​

Aries Retimer Benefits

• Supports separate reference clock (SRNS/SRIS) to accommodate out-of-box PCIe interconnect​ without needing to send REFCLK across the cable
• Retimers can be cascaded for cases with very long cables or large / difficult tray layouts (retimers located both on server and JBoF/JBoG)​
• Deep diagnostic features supported in BMC-tested SDK
