XHTF 330A Time Synchronization Sync. Device

The XHTF330A system is designed with dual redundancy and high reliability and stability. It is mainly configured in a regional center where high frequency punctuality is required and the number of end users is high, and high-precision time synchronization is required. Time and frequency synchronization can be achieved by providing standard time and frequency to terminal devices in the same area.

The device is widely used in time synchronization in the field of communication and navigation, and is suitable for the vehicle environment.

Features
