<div class="paragraph"><h2>Resonators</h2><p>Piezoelectric resonator is an electronic component that is mainly used as a frequency reference in different applications. It has become very popular in the electronics industry due to its high stability, low power consumption and low cost. One of the most popular piezoelectric resonator used in the market is the PT7C5009AN2-2WF.</p><h3>Application Field</h3><p>The PT7C5009AN2-2WF is a miniature, high-frequency crystal oscillator with an industry-leading frequency stability of ±75ppm across temperature and supply voltage variations. It is available in a miniature 0.8x1.6mm package and is suitable for use in automotive, medical, and telecom clocking applications. Due to its small size, it can be used in applications that require a small profile such as home audio systems, mobile phones and PDAs. For example, in a car audio system, it can control the noise cancellation associated with the tweeters, crossover filters, and other speaker components. </p><h3>Working Principle</h3><p>Piezoelectric resonators like the PT7C5009AN2-2WF work by using the piezoelectric effect of crystals and ceramics to generate an electrical signal when subjected to mechanical stress. The material used depends on the specific application, but the basic principle remains the same. When a mechanical stress is placed on the material, an electrical signal is generated. This signal is then amplified by either an external amplifier or an integrated circuit, such as an oscillator.</p><p>The PT7C5009AN2-2WF is a temperature compensated crystal oscillator (TCXO) that is optimized for frequency stability over a wide temperature range of -40° to 85°C. Additionally, it incorporates an on-board voltage regulator that enables operation from 2.5V to 4.0V. The oscillator design also includes an integral heat sink, which helps to improve the oscillator’s stability by providing a highly thermal conducive environment for the crystal and other components. As a result, the oscillator is able to maintain an exceptional frequency accuracy over a wide temperature range, as well as a high shock and vibration resistance.</p><p>In summary, the PT7C5009AN2-2WF piezo-electric resonator is a reliable and cost-effective way to achieve high frequency stability in timing and frequency control applications. Its miniature size allows it to be used in a variety of space-constrained applications, while its onboard voltage regulator, thermal heat sink and sensitivity to stress makes it a highly stable and resilient circuit component.</p></div>
