Crystals play a crucial role in everyday life. Not only do they provide us with moments of serenity and beauty, but they also allow us to explore the mysterious realm of physics. Crystals come in an array of shapes and sizes, bearing different properties and levels of complexity.  MP122A is a crystal oscillator device, which has wide-spread applications and addresses numerous needs of modern day physics.The MP122A is a quartz crystal oscillator module with three pins Pb,Pt and Pk. It works based on the Piezoelectric effect, where incoming electrical energy (in form of a signal) applied to the crystal causes the crystal to vibrate at a certain frequency. The MT122A can reach frequencies of up to 30 MHz.The MP122A\'s application fields are vast and varied. The most common use of the device is as a time-keeper in computers, wristwatches, satellites, and any other gadget which requires an accurate time measure. The MP122A also acts an electrical noise barrier; its vibration cancels out electrical noise. This is essential for industries such as healthcare, military and aerospace, where the presence of electrical noise can interfere with data transmission, or produce undesirable results.The MP122A enables the conduction of oscilloscope, which is a device used to analyse electronic signals; enabling users to view the signals accurately and in detail. It makes for an efficient oscilloscope since the MP122A jumps right onto the next sample, eliminating the delay between observations. Another application of the MP122A is as a carrier or frequency reference. In such cases, the MP122A provides a consistent frequency reference and bandwidths.The working principle of the MP122A is based on the Piezoelectric effect. The device consists of three parts: a quartz crystal, two terminals and an oscillation circuit. The quartz crystal consists of two pairs of electrodes and an internal conductive mass. These components together form an oscillator circuit, which works according to the principle of vibrational resonance.When a voltage is applied to the crystal, mechanical deformation occurs at the crystal surface. This motion is transferred to the mass, causing it to vibrate at its natural frequency. This vibration enters the terminals, and can be measured as an electrical current.The MP122A oscillator device has a plethora of applications in the scientific and engineering fields. Its wide-spread use and efficient working principle make it a key component in many industries and technology applications.
