Broadcom PCI Interface IC, Part #: SS08-0B00-00 | Integrated Circuit | DEX

Broadcom PCI Interface IC, Part #: SS08-0B00-00 allows customers to build systems from simple PCIe connectivity in and outside the box to high performance, low latency, scalable, cost-effective PCIe fabrics for composable hyper-scale compute systems. 

For a complete eco-system with PCIe 4.0 connectivity, system designers and integrators require PCIe 4.0 switches and retimers to interconnect devices within a system and to connect PCIe subsystems together via cables or mid/backplanes. Broadcom has taken an innovative path by repurposing its PCIe 4.0 technology to create a retimer, the PEX88T32, to fill this market need. The PEX88T32 offers a total of 32 bidirectional PCIe 4.0 lanes where one x16 PCIe port can connect to a host and other x16 port to an I/O device, cable connector, or mid-plane. The PEX88T32 retimer uses the same field-tested device architecture and robust long-reach SerDes as the PEX88000 PCIe 4.0 Switch family.

Most servers have difficulty handling serious errors in I/O devices, especially when a device disappears from the system. PEX88T32 DPC/ eDPC implementation allows a downstream link to be disabled after an uncorrectable error or time-out, making recovery possible in a controlled and robust manner. This feature can be enabled via Serial Boot ROM (SBR) code.
