We currently use the DS80PCI402 PCIe Gen 1/2/3 Redriver.
The Redriver is implemented on a PC Add-In Kate to realize the transmission over a 3m copper cable.
The PC card works in some PCs and some do not.
The customer wants to know which requirements apply to a PCIe PC slot for the PC card to work.
Can you tell us something about this?
Furthermore there is a "Rate" select pin. This configures the DS80PCI402 to PCIe Gen 1&2 transmission or(?) PCIe Gen 3 transmission.
Can a card configured to PCIe Gen. 3 work in a Gen 1 or Gen 2 PC slot?
On the other hand, can a card configured to PCIe Gen 2 or Gen 3 work in a Gen 3 PC slot?
