The card is a signal retimer adapter used to secure the link budget to meet the challenging SI
requirements for long PCIe Gen4 channel comprising PCB, connector and cable. It uses
advanced signal conditioning techniques to compensate for the channel attenuation and
remove the impacts of various jitter sources. It connects NVMe SSD or PCIe connectors
via SlimSAS connector (SFF-8654).
Applications
It is targeted for meeting the higher performance PCIe Gen4 interconnection needs of the
following end applications:
• Servers
• Storage Appliances
• Hardware Accelerators
The Motherboard with CPU and BIOS needs to support bifurcation to ensure PCIe
x16 link width to bifurcate two x8 link width or four x4 link width for NVMe SSD,
Otherwise this card can only support PCIe x16 link width.
Features
•High Performance Retimer
•Compensate for channel loss up to 30dB by comprising PCB, connector and cable
•Eliminate deterministic and random jitter
•PCIe Standards and Compatibility
•Support 100MHz reference clock output
•Directly connected to PCIe 4.0 U.2 NVMe SSD by SFF-8654 8i to 2x SFF-8639 cable
•Support bifurcated in quad x4 data link width configuration(CPU and BIOS both
support)
•Support bifurcated in two x8 data link width configuration (CPU and BIOS both
support)
•Build in SlimSAS(SFF-8654) 8i connector 2 sets, pin-out defined by SFF-9402 for
high-performance storage connectivity
•Eight internal lanes per SlimSAS 8i port,
•PCIe Standard Full-profile bracket pre-installed and also a low-profile bracket for
small form factor computer.
Specifications
