Pinneberg, Germany. TEWS Technologies introduced its TXMC391, a conduction-cooled XMC module featuring four 1000BASE-KX Ethernet interfaces offering precision networking, enhanced thermal stability, and adaptable backplane connectivity. It is designed around Intel's I210IS Gigabit Ethernet controllers and leverages a PCIe Gen2 x4 interface through an onboard switch. For consistency and flexibility, each channel is equipped with its own 16 Mbit serial flash.
Key Features:
- IEEE 1588 / 802.1AS PTP support for precision time synchronization
- IEEE 802.1Qav AVB support (with software extensions)
- PXE & iSCSI boot supported via per-port flash memory
- Fully compliant P16 backplane I/O (VITA 46.9 X12d mapping)
- Extended temperature range: -40°C to +85°C (card edge)
- Conduction-cooled (ANSI/VITA 20), ideal for rugged deployments
- Onboard I²C temperature sensor for thermal monitoring
“The TXMC391 is designed for high-precision Ethernet communication in harsh environments,” said Jan Zimmermann, General Manager at TEWS Technologies. “From aerospace to industrial control, it delivers rock-solid performance, synchronization accuracy, and integration flexibility.”
The module is ideal for defense, aerospace, industrial automation, and test and measurement applications.
