Catalyst-X™ Carrier Card

All Catalyst PXIe-GbE modules are built on the RADX patent-pending Catalyst-X™ carrier card — a purpose-designed PXIe/CPCIe single-slot carrier that integrates standard PCIe NIC cards into the PXIe form factor. PCIe Gen 4 ×8 host interface ensures full bandwidth utilization for all three NIC configurations. Standard vendor drivers are used throughout; no custom RADX drivers are required.
