T220-C PCI 授时卡
Learn about our PCI timing solutions
T220-C PCI授时卡面向工业控制、通信及测试测量等传统PCI架构平台,可直接插入主机,为系统提供高精度时间同步、定时中断及多种授时接口能力。支持卫星授时、PTP、B码及PPS+TOD等多源接入,并通过优先级切换与本地时钟驯服保障连续同步能力,同时支持PTP主从时钟、NTP服务、PPS、TOD、IRIG-B及频率输出等功能。内置高稳恒温晶振,在外部参考异常时可自动切换或进入守时状态,持续提供稳定时间基准。通过PCI总线支持时间读取、系统对时及API调用,实现周期中断与定时闹钟功能。
适用于科研计量、通信、电力、工业自动化及传统 PCI 平台升级。
