Working Principle of ZL30321GGG2

The ZL30321GGG2 is a high-performance oscillator that works according to crystal thermodynamic principles. It consists of a precision quartz crystal, a temperature-compensated circuit, and a frequency control system.The quartz crystal oscillator works according to the so-called piezo-electric effect. The quartz crystal itself has an electrical property called the piezo-electric effect. When an electric field is applied to a quartz crystal, the vibration frequency of the crystal\'s natural lattice is modified. The resulting frequency is dependent on the specific crystal being used and the voltage being applied. A temperature-compensated circuit is used to control and maintain a stable frequency over time and temperature range. It consists of a reference oscillator, a temperature sensor and a timing control circuit. The reference oscillator provides a reference clock signal for the timing control circuit. The temperature sensor measures the temperature of the crystal and the timing control circuit adjusts the frequency accordingly to compensate for any temperature drift.The frequency control system is used to provide dynamic frequency adjustment and finely tune the frequency. It consists of a frequency counter, a frequency control circuit, and a voltage-controlled oscillator (VCO). When the VCO detects a frequency discrepancy, it sends a signal to the frequency control circuit to adjust the frequency. The frequency counter is used to measure the actual frequency and is compared to the desired frequency.

Conclusion

The ZL30321GGG2 is a high performance, low jitter oscillator designed to provide application-specific timing solutions. Its precision quartz crystal, temperature-compensated circuit, and frequency control system work together to provide reliable and accurate timing over temperature and in hostile operating environments. It is suitable for a host of timing applications in industrial, medical and aerospace installations.
