When it comes to crystal oscillators, one may think of quartz crystals. In fact, these two are equivalent. So what is the difference between crystal oscillators and crystals? Give a brief analysis.

  1. Crystal oscillators are active

  For crystal oscillators, due to their active nature, they contain an oscillator that can operate independently and produce stable frequency output. So in terms of the composition of integrated circuits, resonant circuits naturally occur, but the prerequisite is that power supply is needed to vibrate. Generally speaking, experiments can be conducted through several patches.

  2. Crystals are passive

  For such passive crystals, crystals (such as quartz crystals) are passive and cannot generate oscillations independently. An external oscillation circuit is needed to drive it, which is called an integrated circuit.

  3. Structure and application: Crystal oscillators are usually packaged in a metal shell, which contains crystals, oscillation circuits, and amplification circuits inside. This allows crystal oscillators to be directly integrated into electronic devices, providing a stable frequency source. And the crystal itself is just a small piece of object, which needs to work in conjunction with external oscillation circuits.

  4. Classification and naming: In professional classification, crystal oscillators are usually referred to as "clock oscillators" or "active crystal oscillators", while crystals are referred to as "passive crystal oscillators".

  Through the above points, distinguish between crystal oscillator and crystal oscillator. In the process of equipment operation, the configuration of the oscillator is very important, and it needs to be selected according to different adaptation ranges to better demonstrate the quality of the crystal oscillator. At the same time, for the sealing and stability of the crystal oscillator, all parameters must meet the standards in order to avoid faults and ensure the accuracy of operation is improved.
