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.
The LRES6080PF-4SFP28 TimeSync card is based on the Intel E810 NIC controller and Microchip PLL and supports 4 port of 25/10/1GbE . It uses 1PPS and 10MHz to synchronize the host system with an external clock source, and supports both 1588v2/PTP and SyncE synchronization methods. It achieves high clock accuracy in master and slave modes, while additional hardware enhancements ensure reliability and accuracy, and provide greater flexibility and simplicity for timing synchronization deployments.
TimeSync:
• Quad Port SFP28 for 25G/10GbE
• Supports PTP Transparent Clock (TC) Boundary Clock (BC) OC (Master / Slave)
• PTP over IPv4 (IEEE-1588v2) / SyncE
• GNSS enables integrated support for frequency, phase, and time synchronization with global navigation satellite systems
• Dual SMA (10 MHz / 1PPS), with configurable input and output
• Full HW and SW TimeSync solution based on industry leading DPLL, high-precision clock solution,Servo stack and PTP1588
• high-precision OCXO +/-5ppb to keep 4h accuracy< 1.5us without External source assistance

• RDMA: Supports iWARP and RoCEv2, and can be selectively configured for each port.
• SR-IOV (Single Root I/O Virtualization): 8PFs，256VFs，768VSIs，256 Queues per PF，2K Queue pairs total
