ECIA EIA-974 PDF

This specification defines the terminology and physical requirements for the mating interface and physical characteristics of the Mini Multilane Connector. The dimensions specified apply to the various sizes of the family, which covers a variety of circuit sizes, see EIA-975 (Specification for Mini Multilane 4X Unshielded Receptacle Shell and Plug Connectors) and EIA-976 (Specification for Mini Multilane 4X Shielded Receptacle Shell and Plug Connectors).

Fibre Channel, SAS, and other standards define requirements on the characteristic impedance and ability to transmit multi-gigabit signals for cable assemblies and backplanes. When this connector is used in such an interconnect, it is subject to these requirements.

The SFF Committee activities support the requirements of the storage industry, and it is involved with several standards.
