将 Time Tagger 连接至外部 FPGA

了解如何通过 QSFP+ 接口将 Time Tagger X 连接至外部 FPGA,实现高速信号输出。

Time Tagger 20Time Tagger Ultra 仅提供 USB 接口; Time Tagger X 还配备 QSFP+ 接口,可将信号以最高 1.2 GTags/s 的数据速率输出至另一块 FPGA。该接口会引入一定延迟,即时间标记经 QSFP+ 接口传输并可供第二块 FPGA 使用所需的时间。由于采用以太网协议,延迟约为 10 µs。

请注意,Time Tagger X 的 FPGA 输出兼容 Opal Kelly XEM 8320 FPGA 开发板。为简化第二块 FPGA 的开发,我们提供可按需求定制的基础 FPGA 软件。详细信息请参阅文档中的 FPGA 深度指南;参考设计指南可在 GitHub Repository 中获取。
