The XHTF1067 GPS/Beidou Synchronous Clock Module is a high-precision punctual module that integrates GPS, Beidou receiver and high-stability crystal oscillator. It uses intelligent tame algorithm to lock the crystal oscillator to GPS or Beidou.
The XHTF1067 GPS/Beidou Synchronous Clock Module is a high-precision punctual module that integrates GPS, Beidou receiver and high-stability crystal oscillator. It uses intelligent tame algorithm to lock the crystal oscillator to GPS or Beidou. In the locked state, the frequency accuracy of the output signal is better than 1×10-12/day; when the GPS and Beidou signals are not available, the maintenance algorithm control mode is entered, and the high accuracy of the frequency and the high precision of the time can be maintained.
This clock module can be used for BBU device integration of communication base stations, BITS device integration, power system clock synchronization device integration, and broadcast clock synchronization device integration.
Features
● Highly integrated and miniaturized single board structure;
● Using intelligent tame algorithm and high accuracy;
● Adopt intelligent maintenance technology and high punctual performance.
