PEX88T32 is a PCIe Gen 4.0 Retimer with 32 bi-directional PCIe lanes and the industry’s best SerDes technology with extended reach. Broadcom has taken an innovative path by re-purposing its PCIe Gen 4.0 Switch to create a retimer, the PEX88T32, to fill this market need. The PEX88T32 offers a total of 32 bi-directional PCIe Gen 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 chip architecture and robust long-reach SerDes as PEX88000 PCIe Gen 4.0 Switch family.

Additional info

Broadcom PEX88000 switches allow 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. In order to have a complete eco-system for PCIe Gen 4.0 connectivity, system designers and integrators need PCIe Gen4 switches and retimers to interconnect devices within a system and to connect PCIe sub-systems together via cables or mid/backplanes.
