The T221-C PCIe Time Synchronization Card is designed for modern servers, industrial control systems, and edge computing platforms. It utilizes an open-source architecture based on the Time Appliances Project and employs an FPGA to implement hardware-adjustable clocks, PPS and TOD synchronization, timestamping, and frequency measurement, providing the host with an independent, high-precision time reference. The card features a built-in u-blox LEA-M8T multi-constellation GNSS receiver and a highly stable, tamed clock, capable of stably outputting satellite time as 1PPS and 10 MHz signals while maintaining time continuity even when GNSS loses lock. Through Linux drivers, it provides PHC and PPS device interfaces, and\u2014in combination with software such as ptp4l, phc2sys, and chrony\u2014builds a PTP master clock, slave clock, and boundary clock system. The front panel features a GNSS antenna and multiple SMA time-frequency interfaces.<\/p>\n
