- PCIe 1.0, 2.0, 3.0 and 4.0 support
- 32 bi-directional PCIe lanes – 16 lanes up and 16 lanes down
- Industry’s best SerDes technology with extended reach (up to 39 dB loss)
- Low-power SerDes (under 90 mW per Lane)
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.
