T221-N Time-Synchronized Ethernet Card
Learn about our PCI timing solutions
The T221-N Time-Synchronized Ethernet Card is a professional-grade PCIe network interface card designed for next-generation high-precision time-synchronized networks. Based on the Intel® Ethernet Controller E810 architecture, it integrates IEEE 1588v2 PTP, SyncE (Synchronous Ethernet), GNSS time source inputs, and a high-precision DPLL clock system, providing nanosecond-level time alignment capabilities in complex network environments. This product is intended for 5G front-haul/mid-haul networks, high-frequency trading systems in the financial sector, power grid synchronization systems, industrial automation, and distributed computing infrastructure in data centers. It can be deployed as a PTP master clock (GM), boundary clock (BC), or slave clock (Slave/Time Receiver).
Important Features
