SS03-0B00-00

• Broadcom PEX88080 device, 82 PCI Express Lanes
• PCI Express Gen4 Generation
• Programmable Port and Lane Configuration
• Lifecycle Status: Production

The SS03-0B00-00 is a Broadcom PEX88080 82-lane programmable PCI Express Gen4 device. A PCIe switch of this class expands a single upstream link from a host into multiple downstream ports, letting one root complex address more endpoints than its native lane count allows, and supports peer-to-peer transfers between endpoints without routing traffic through the host. Broadcom lists the SS03-0B00-00 as a production part. Note that this catalogue record carries only one attribute, so no package, voltage, thermal or port-configuration data is available for the SS03-0B00-00 beyond the manufacturer part identification.

PCIe Gen4 switches of this scale sit between a host CPU and a large population of endpoints, which is how storage and accelerator systems fan out far beyond the lanes a processor natively provides. Typical placements are NVMe storage backplanes connecting dozens of drives, GPU and accelerator baseboards where peer-to-peer transfers bypass host memory, composable infrastructure chassis, and high-port-count network and capture appliances. The programmable element allows lanes to be grouped into different port widths to match a particular chassis topology. Buyers are storage and server OEMs, accelerator system designers and systems integrators building PCIe fabrics.
