T220-V VPX Time Synchronization Card

Learn About Our VPX Time Synchronization Solutions

The T220-V VPX Time Synchronization Card is designed for high-reliability systems such as embedded computing, communication control, and synchronized data acquisition. Featuring a fully enclosed 3U VPX design, it can be directly integrated into a VPX chassis to provide a compact time synchronization solution. The product uses GPS/Beidou satellites as its time reference and features a built-in GNSS receiver and a highly stable temperature-compensated crystal oscillator (TCXO). It can output various time signals, including NTP, 1PPS, TOD, and B-DC, to meet the synchronization requirements of systems and peripheral devices. When satellite signals are abnormal or interrupted, the onboard clock enters a time-holding state to maintain time continuity, thereby reducing the risk of system out-of-sequence events and interruptions. The product features high integration and environmental adaptability.

Suitable for applications such as industrial automation, communications, power systems, radio navigation monitoring, synchronous data acquisition, and precision time-frequency comparisons.
