【Abstract】 This paper describes the design and implementation of a TTP hub with high transmission rate in detail, including FPGA-based hub architecture design, functions management, time synchronization, receive gating and frame forwarding, and designs corresponding fault avoidance strategies for common faults. All designs have been verified on the board and can achieve highprecision time synchronization within 25 ns.更多还原
