A clientadapter – plugged into the upstream port of a backplane (Gen2 or Gen3) – is connected via the host adapter to a free PCIe slot in the host system.
The client adapter X8 supports 8 PCIe Gen3 lines which are connected via 4 Mini Display port cables (2 lanes each) to the host adapter.
A jumper can be used to select whether the cabling is inside (e.g., Case #2) or outside (Case #3, Case #4) of a case.
With Digital Devices cables, the optimal setting in the host and client adapters is done automatically.
Cable lengths from 0.5 – 7 m are possible.
There is a Low Profile and a Full Profile slot bracket available.
Achievable data rates | Cable 1 | Cable 2 | Cable 3+4 |
PCIe Generation1 | 5 Gbit/s | 10 Gbit/s | 20 Gbit/s |
PCIe Generation2 | 10 Gbit/s | 20 Gbit/s | 40 Gbit/s |
PCIe Generation3 | 16 Gbit/s | 32 Gbit/s | 64 Gbit/s |
Note: The PCIe specification only provides for PCIe x1 as a mandatory fallback option.
