Panmnesia, a pioneer in AI infrastructure link solutions, announced sample availability of its PCIe 6.0/CXL 3.2 Fabric Switch—the industry's first CXL switch silicon supporting port-based routing (PBR). The company is currently in the process of providing switch silicon samples to early access partners.

Panmnesia's switch is a hybrid solution that supports both PCIe Gen 6 and CXL 3.2 protocols on a single chip, while maintaining full backward compatibility with all previous PCIe and CXL generations. Fully implemented in strict accordance with the CXL 3.2/PCIe 6.0 specifications, it ensures complete standards compliance and seamless interoperability across all subprotocols. The switch can also operate in PBR mode and hierarchy-based routing (HBR) mode.
