Increasing growth in 5G RAN and edge deployments is driving demand for high-precision timing synchronization across the network. Meet these challenging requirements head-on with a standards-based PCIe adapter that provides greater flexibility at a lower price point than single-purpose timing appliances.

Most 5G RAN deployments use 1588 PTP SyncE or both to ensure required timing synchronization. Both of these synchronization methods are supported by the E810-XXVDA4T while additional hardware enhancements ensure reliability and accuracy and provide greater flexibility and simplicity for timing synchronization deployments.

Support for synchronization

Synchronous Ethernet (SyncE) delivers frequency synchronization over Ethernet between SyncE-enabled devices. Extends traditional telecom timing architecture to commercial-off-the-shelf (COTS) Ethernet solutions.

IEEE 1588 PTP enables synchronization of systems on a network through the transfer of timing data (including frequency phase and time of day) with hardware timestamping in PTP packets.

Onboard high-precision oscillator maintains high accuracy during holdover (when the synchronization source is not available) providing up to four hours with less than +/- 1.5 microsecond of phase error.

Hardware features for deployment flexibility

Optional GNSS mezzanine enables integrated support for frequency phase and time-of-day synchronization with Global Navigation Satellite Systems including GPS Galileo GLONASS BeiDou and QZSS. Available on E810XXVDA4TGG1 only. Subminiature version B (SMB) coaxial connector allows connection to an external active GNSS antenna.

Dual external SubMiniature version A (SMA) coaxial connectors allow connection to external 1PPS timing sources such as GNSS signaling devices and to timing recipients enabling the network adapter to act as a grandmaster and as a timing source for other equipment. The output capability provides a way to audit the phase accuracy of each node.

U.FL connectors embedded coaxial connectors allow 1PPS signal connectivity between the adapter and motherboard or another adapter. Dedicated send and receive U.FL ports are embedded on the adapter. E810-XXVDA4T Product Brief Intel® Ethernet 800 Series Network Adapters

All 800 Series products include these technologies | Greater Predictability at Scale

As modern data centers scale a key challenge is to provide scalable predictable application-level performance. Application Device Queues (ADQ) technology improves performance scalability and predictability by dedicating queues to key workloads delivering predictable high performance through dramatically reduced jitter.

Increasing the predictability of application response times by lowering jitter enables more compute servers to be assigned to a task and can allow more users to access the system providing a better end-user experience. Even applications that are not large scale can benefit from higher consistency enabling them to meet service-level agreements (SLAs) more easily.

ADQ enables application-specific data steering signaling and rate limiting using an optimized application thread to device data path. This ability to dedicate queues and shape network traffic not only increases performance it reduces latency and improves throughput.
