Intel Ethernet Network Adapter E810-XXVDA4T - 25GbE PCIe Card with Precision Time Protocol and SyncE Support

Designed to meet the demanding synchronization requirements of modern 5G RAN and edge deployments, the Intel Ethernet Network Adapter E810-XXVDA4T offers advanced features that enhance network reliability and flexibility. This PCIe adapter supports industry standards such as IEEE 1588 PTP and Synchronous Ethernet (SyncE), enabling precise timing synchronization essential for 5G and telecom infrastructure. With onboard high-precision oscillators, it maintains accuracy during holdover periods, ensuring less than +/- 1.5 microseconds of phase error for up to four hours, which is critical for maintaining network stability during source outages. The adapter’s support for synchronization methods extends to integrated hardware enhancements, simplifying deployment and ensuring compliance with telecom timing architectures.

The E810-XXVDA4T provides optional GNSS mezzanine support, including GPS, Galileo, GLONASS, BeiDou, and QZSS systems, facilitating integrated frequency, phase, and time-of-day synchronization. This feature, available on specific models, includes a subminiature SMB coaxial connector to connect external GNSS antennas, improving signal reception and accuracy. Dual external SMA connectors enable connection to 1PPS timing sources like GNSS signals, allowing the adapter to act as a grandmaster clock and deliver phase accuracy auditing capabilities across the network. Embedded U.FL connectors support 1PPS signal connectivity to motherboards or other adapters, providing versatile integration options for diverse deployment scenarios.

Flexibility in configuration is a key feature of this network adapter. It supports multiple high-speed Ethernet configurations, including quad-port SFP28 modules for 25 and 10 GbE connectivity, making it suitable for data center and telecom environments. The adapter complies with RoHS standards and is designed with a full-height bracket, ensuring compatibility with standard server chassis. Its support for Intel® Ethernet Optics, along with active optical cables and direct attach cables, enables seamless integration into various network architectures. Whether used as a primary timing source or as part of a larger synchronization network, the Intel E810-XXVDA4T delivers reliable, standards-based performance for high-precision timing and high-speed data transfer needs.
