Applies to Closed3602 Coaxlink Octo, 3603 Coaxlink Quad CXP-12, 3603-4 Coaxlink Quad CXP-12, 3620 Coaxlink Quad CXP-12 JPEG, 3620-4 Coaxlink Quad CXP-12 JPEG, 3623 Coaxlink Quad CXP-12 Value, 3624 Coaxlink Quad CXP-12 DF and 3625 Coaxlink QSFP+.

The PCI Express Interface implements a PCIe end-point interface and provides electrical power to the on-board circuits.

The 8-lane Rev 3.0 PCIe end-point:

● complies with Revision 3.0 of the PCI Express Card Electromechanical specification,
● supports 1-lane, 2-lane, 4-lane and 8-lane link width,
● supports PCIe Rev 3.0 link speed (8.0 GT/s with 128b/130b coding),
● supports PCIe Rev 2.0 link speed (5.0 GT/s with 8b/10b coding)
● supports the PCIe Rev 1.0 link speed (2.5 GT/s with 8b/10b coding),
● supports payload size up to 512 bytes,
● offers the optimal performance when it is configured for 8-lane PCIe Rev 3.0 link speed (8 GT/s).
