TEWS Technologies’ XMC (Switched Mezzanine Card) I/O product family delivers a versatile range of high-quality interface modules designed for demanding embedded applications — including industrial automation, communications, networking, and ruggedised platforms.
With a broad array of Ethernet, serial, and FPGA-based modules, the XMC portfolio enables developers to integrate flexible I/O capabilities into PCIe-based systems while maintaining compliance with ANSI/VITA XMC standards for reliability and interoperability. The product range includes options for high-speed Gigabit and 10 Gigabit Ethernet, various serial protocols such as RS-232, RS-422, and RS-485, as well as FPGA modules that offer customisable logic for specialised processing needs.
This diversity ensures that system designers can select the optimal interface to meet their specific performance, bandwidth, and environmental requirements, making the XMC family suitable for both standard commercial and harsh industrial environments.
TEWS XMC I/O products are tailored for system integrators, embedded designers, and OEMs who require modular, rugged interface solutions that can be easily integrated into PCIe-based or carrier-supported systems. They are particularly suitable for industrial automation, test & measurement, networking infrastructure, and defence platforms where reliable I/O and extended environmental performance are critical.
Highlights of the line
