Intel® Ethernet 800 Series Network Adapters
Intel® Ethernet Network Adapter E810-XXVDA4T
High-precision timing synchronization with IEEE 1588 PTP, SyncE and GNSS
Key Features
- Quad Port SFP28 for 25/10GbE
- IEEE 1588 Precision Time Protocol (PTP)
- Synchronous Ethernet (SyncE)
- Onboard high-precision oscillator
- Optional GNSS mezzanine
- SMA, SMB, and U.FL connectors
Increasing growth in 5G RAN and edge deployments is driving demand for high-precision timing synchronization across the network. This standards-based PCIe adapter 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. The E810-XXVDA4T supports both methods, with additional hardware enhancements ensuring reliability, accuracy, flexibility, and simplicity for timing synchronization deployments.
Support for Synchronization
Synchronous Ethernet (SyncE) delivers frequency synchronization over Ethernet between SyncE-enabled devices, extending 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.
The 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. This feature is available on the E810XXVDA4TGG1 model only.
A 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 timing recipients, enabling the network adapter to act as a grandmaster and timing source for other equipment. The output capability provides a way to audit the phase accuracy of each node.
U.FL connectors, which are 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.
Flexible Configurations
Intel® Ethernet Optics, and specification-compliant Active Optical Cables and Direct Attach Cables, can support multiple configurations.

All 800 Series Products Include These Technologies
Greater Predictability at Scale
As data centers scale, providing scalable, predictable application-level performance is crucial. 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, but also reduces latency and improves throughput.
Increase Throughput and Lower Latency
Remote Direct Memory Access (RDMA) provides high throughput and low-latency performance for modern high-speed Ethernet by eliminating three major sources of networking overhead: TCP/IP stack process, memory copies, and application context switches. Intel Ethernet 800 Series Network Adapters support all Ethernet-based storage transport, including iWARP, RoCEv2, and NVMe over Fabric.
RoCE (RDMA over Converged Ethernet): RoCEv2 substitutes the InfiniBand physical layer and data link layer with Ethernet, operates on top of UDP/IP, and is routable over IP networks.
iWARP, IETF standard protocols based: Delivers RDMA on top of the pervasive TCP/IP protocol. iWARP RDMA runs over standard network and transport layers and works with all Ethernet network infrastructure. TCP provides flow control and congestion management and does not require a lossless Ethernet network. iWARP is a highly routable and scalable RDMA implementation.
Improve Packet Processing Efficiency
Dynamic Device Personalization (DDP) customizable packet filtering, along with enhanced DPDK, supports advanced packet forwarding and highly-efficient packet processing for both Cloud and NFV workloads.
The 800 Series firmware loads an enhanced DDP profile with many workload-specific protocols at driver initialization for greater flexibility. When multiple 800 Series adapters are present in a system, the pipeline on each adapter can be programmed independently with a different DDP profile.
Increase Timing Accuracy
Intel Ethernet 800 Series supports both IEEE 1588 PTP v1 and v2 with a two-step option. The products provide increased accuracy at single-digit nanosecond level, and can report the reception time for every packet. This level of timing accuracy can help ensure tight synchronization across network deployments ranging from 5G RAN to financial services, industrial automation, and energy monitoring.
Protect, Detect, and Recover
Zero Trust is a security design strategy centered on the belief that organizations, by default, should not automatically trust any request for system access. This includes requests coming from outside, as well as inside its perimeters. Zero Trust demands that every access request be verified before granting access.
The 800 Series implements a design philosophy of platform resiliency with 3 attributes compliant with the NIST Cybersecurity Framework, including NIST 800-193 Platform Firmware Resiliency Guidelines: Protect, Detect and Recover. By design, the Hardware Root of Trust in the 800 Series protects the firmware and critical device settings with authentication for every access. Signed firmware updates and the Hardware Root of Trust protect and verify critical device settings with built-in corruption detection and automated device recovery. Together these features ensure the device safely returns to its originally programmed state.
