The 3.0 release of the successful COM Express computer-on-module standard includes a new pinout type. This enables a faster data transfer rate of up to 10 Gbps, thereby expanding the applicability of COM Express in terms of server applications. Of course, the PCB connectors required to connect the baseboard and the COM module need to meet these increased requirements.
Unlike the type 6 pinout, the new type 7 pinout does not include any audio or video interfaces. As such, it does not represent a substitute for type 6; instead, it expands the range of COM Express applications in terms of server applications. The audio and video interfaces on the previous pinout type have been replaced with four 10 GB Ethernet KR lanes and 32 PCI Express lanes to increase the data transfer rate. These new features are relevant for use in video on demand in the telecom segment, for example, as well as medical or security technology applications.
These areas of application require reliable PCB connectors, which are essential for securely connecting the baseboard with the COM module and guaranteeing high data transfer rates of up to 10 Gbps. Colibri® connectors from ept are perfectly suited for achieving these high data transfer rates – they feature optimized contact design and deliver first-rate signal integrity, even at 10 Gbps and higher. They are therefore ideally suited for PCI Express Gen3 applications with 8 Gbps or 10 Gbps Ethernet (10GBase-KR); the pinout type 7, among other features, is designed for this. S-parameters are available on request from ept for use in simulating your proprietary designs.
The Colibri® connector series with a pitch of 0.5 mm impresses with extremely robust design and a high degree of versatility. Both 220-pin and 440-pin versions for board-to-board distances of 5 and 8 mm are available. Colibri® products are compatible with all popular connector systems on the market. This has been proven by signal integrity tests carried out by the Fraunhofer Institute. The testers compared Colibri® connectors to other COM Express connectors and also tested the two connector types in combination, achieving excellent results in each scenario.
