T220-C PCI Timing Card

Learn about our PCI timing solutions

The T220-C PCI Time Synchronization Card is designed for traditional PCI architecture platforms, such as industrial control, communications, and test and measurement systems. It can be directly插入 into a host computer to provide the system with high-precision time synchronization, timing interrupts, and a variety of time synchronization interfaces. It supports multi-source input, including satellite timing, PTP, B-code, and PPS+TOD, and ensures continuous synchronization through priority switching and local clock taming. It also supports PTP master and slave clocks, NTP services, PPS, TOD, IRIG-B, and frequency output. It features a built-in high-stability temperature-compensated crystal oscillator (TCXO) that automatically switches or enters a time-holding state when the external reference fails, continuously providing a stable time reference. Through the PCI bus, it supports time reading, system synchronization, and API calls, enabling periodic interrupts and timed alarm functions.

Suitable for scientific measurement, communications, power systems, industrial automation, and upgrades to traditional PCI platforms.
