T200 GNSS Synchronous Clock Module

Learn about our GNSS Disciplined Oven-Controlled Crystal Oscillators

The T200 GNSS Synchronous Clock Module is a highly integrated time and frequency module that integrates a high-stability crystal oscillator and GNSS receiver, outputting precise and stable 10MHz frequency signals and 1PPS time signals. The module boasts ultra-low phase noise, excellent timekeeping capabilities, and a wide operating temperature range (-20°C to +70°C), making it suitable for use in complex environments such as vehicles, aircraft, and ships. Using co-frequency phase shifting technology, the module improves crystal oscillator control accuracy, enabling it to autonomously generate stable time and frequency signals even when satellite signals are lost, ensuring system operation. Its high reliability and compact design meet diverse high-precision timing requirements.
