    • Crystals, Oscillators, ResonatorsCrystals, Oscillators, Resonators Crystals, oscillators and resonators each have their own characteristics and different application scenarios. In actual design, frequency stability, power consumption, cost and environmental factors need to be considered comprehensively. 1. What are Crystals? Definition: Crystals are typical passive devices (Passive Device), the main component of which is quartz (SiO₂), which use the piezoelectric effect to realize the mutual conversion of mechanical vibration and electrical signals. ‌Working principle‌: When an external voltage is applied, the crystal generates a resonant signal of a fixed frequency through mechanical vibration, but it does not have the driving ability itself and needs to rely on external circuits (such as amplifiers and load capacitors) to maintain oscillation. ‌Application scenario‌: Commonly used in clock circuits (such as microcontrollers and communication equipment) to provide reference frequency, and the nominal frequency range covers kHz to MHz (such as 32.768kHz or 24MHz). 2. What are Oscillators? Definition: Oscillators are active devices (Active Device), which integrate internal amplifier circuits, feedback resistors and voltage stabilization components, and can independently generate stable frequency signals. ‌Core features‌: √Directly output clock signals (such as sine waves or square waves) without external driving circuits‌. √Pins usually include power supply (VCC), ground (GND), output (OUT), etc.,…
