SFF-SIG (Small Form Factor Special Interest Group) is a Standards family primarily focused on the development of modular embedded computers and controllers.

Many SFF-SIG specifications utilize proven interfaces such as PCI Express® and USB when defining single-board systems and COM (computer-on-module) form factors.

SUMIT

SUMIT is an electromechanical connectorization specification that enables all common serial and legacy chipset expansion busses for next generation products. It is a stackable, I/O-centric, serial expansion approach that is independent of any particular board form factor. It supports PCIe, USB, LPC, SMBus, and ExpressCard signals on a single high-speed connector.

As the demand for higher frequencies and wider bandwidths continue their relentless march upward, RF connectors need to keep up and even exceed this demand. Mating the RF connector to a PCB or substrate requires careful consideration of several factors to get the full performance...
VITA 66 has been around for some years now. What goes into this standard continues to expand. VITA 66 is an evolution to increase your options inside the existing VITA 46 (VPX) market space. Samtec is pleased to announce the addition of our VITA 66 Landing Page. We are designed i...
In this video from DesignCon 2022, Keysight’s Mike Resso refers to 224 Gbps as a “blindingly fast speed.” Ten years from now, when 224 is old-hat and commonplace, we will look back at that statement and smile at how far we’ve come since those technologically backward, archaic day...
If you need a connector and you don’t know exactly what you’re looking for, where on the Internet do you go first? You go to some sort of search engine, whether it be Google, Octopart, Digikey, or an on-site search like the one on Samtec.com. We’ve been working on several upgrade...
I recently attended the New York International Auto Show. While I was mesmerized by the new Corvette, the Huracán STO, and the GT-R, in reality I am thinking about updating my WRX. Whatever the budget, high-performance cars are high-precision engineered solutions using state-of-t...
