T220-C PCIe PCI timing card

Learn about our PC timing solutions

The T220-C PCI timing card supports GPS/BD multi-mode receivers and a local oven-controlled crystal oscillator (OCO), providing precise time information for computers. It can also provide external time services, supporting IEEE1588, B-code, 1PPS, and TOD timing signals. This card transmits time information and timer interrupt signals to the computer via the PCI interface, synchronizing the computer software time with the card's time. Its built-in high-temperature OOCO ensures that even if all reference time sources are disconnected, the card's internal, highly stable oscillator can maintain continuous operation within a specified accuracy range for a specified period of time, thus providing a highly accurate time signal to the computer system and significantly improving the product's reliability.

Applicable fields: scientific research measurement, communications, electricity, transportation, industrial automation, etc.
