GS5020 Time & Frequency Module - 100MHz Clock
Products Introduction
The GS5020 time and frequency module is an airborne clock reference module designed for avionics applications.
It integrates high-stability, shock-resistant 10MHz and 100MHz clock sources, and accepts external satellite signals or 1PPS inputs as reference for disciplining the internal clock sources. Utilizing advanced intelligent digital phase-locked loop (PLL) algorithms, the module achieves fast disciplining to the external reference and outputs high-precision 100MHz clock signals and 1PPS signals. Module operating status is reported in real time via the serial interface.
The module features dual backup clock sources in a redundant design, with the two temperature controlled crystal oscillator operating independently without mutual interference, significantly enhancing system reliability. A key advantage of the product is its integrated modular design, offering plug-and-play functionality that allows users to easily expand the system based on the signal types provided by the clock module.
