PCI-SIG specifications define standards driving the industry-wide compatibility of peripheral component interconnects. Members regularly review them, providing commentary and change requests when necessary. These requests are considered by technical workgroups and applied as appropriate, resulting in collaboratively devised specifications benefiting millions of platforms and add-in devices.
Engineering Change Request Process
PCI-SIG members may submit requests to change specifications here. The Engineering Change Request process and form can be found here.
Purchasing Specifications
PCI-SIG members may access specifications online, at no cost, using the Specification Library. Members may filter their search by technology type, revision, and the type of document. Select the appropriate filters and then select the Filter button to initiate your search. Alternatively, members may purchase a hard copy of the specifications, at a reduced member rate, here.
Non-members who are interested in purchasing specifications may submit their order here.
PCI Code & ID Assignment Specifications
The PCI Code & ID Assignment Specifications are accessible to non-members without charge here. PCI-SIG members can download these specifications directly from the Specifications Library below.
The M.2 form factor is intended for Mobile Adapters....view moreThe M.2 form factor is intended for Mobile Adapters. The M.2 is a natural transition from the Mini Card and Half-Mini Card (refer to the PCI Express Mini CEM Specification) to a smaller form factor in
both size and volume. The M.2 is a family of form factors that enables expansion, contraction, and higher integration of functions onto a single form factor module solution.

The specification uses a qualified subset of the same signal protocol, electrical definitions, and configuration definitions as the PCI Express Base Specification, Revision 2.0. Where this specification 5 does not explicitly define PCI Express characteristics, the PCI Express Base Specification governs.

LTE category 5 peak data rates are 320 Mbps downlink; 75 Mbps uplink. Most USB 2.0 implementations achieve a maximum of about 240 Mbps throughput. Looking longer term, the ITU has set a target of 1 Gbits/s for low mobility applications for IMT Advanced.
