3.3. COM Express Compliance

The COMe-bID7 can be offered in two different versions regarding the compliance to the COM Express COM.0
specification Rev 3.0 or Rev 3.1.
The main different between both is the support of PCIe Gen 4.0 and the pin definition for the 10G LAN interfaces

COM.0 Rev 3.1: default configuration:

10G LAN - CEI (Common Electrical Interface) mode
This mode is used on COMe-bID7 modules for carriers/backplanes designed according to the COM Express
specification COM.0 Rev 3.1 and newer. In comparison to the legacy mode the CEI mode consists of a fewer set of
