Crystals

Crystals play a vital role in modern electronics, owing their success to their ability to oscillate at a fixed frequency, with great accuracy and stability. Crystals are an essential component in the vast majority of modern electronics, fulfilling a number of roles, including oscillators, frequency references and timing devices. However, when selecting a crystal for a specific design there are many considerations to take into account, including the desired frequency and stability, the size of the package, the operating temperature range and whether the crystal is leaded or lead-free.

Working Principle

The CA-301 50.2600M-K: PB FREE operates on a quartz crystal principle. This principle states that a quartz crystal will vibrate in resonance at a certain frequency when an alternating voltage is applied. This frequency is determined by the size of the cut quartz rod which makes up the crystal. The CA-301 uses a mechanically-cut quartz crystal to oscillate at a very precise frequency. The crystal is connected to two oscillation circuits which provide an oscillation signal that is transmitted to the circuit under test. This signal is then received and used to provide the reference frequency for the circuit. The quartz crystal operates by generating an electric field from a charge when an AC signal is applied to it. This electric field causes the quartz rod to vibrate and the oscillation frequency is determined by the size of the cut rod. This frequency is extremely stable and only changes by a very small amount.

Conclusion

The CA-301 50.2600M-K: PB FREE has many advantages over other crystal oscillators, being highly accurate, stable, and possessing a wide range of operating temperatures. This crystal is ideal for use in a variety of high frequency and precision timing applications, with the most common being clock generator for embedded systems, GPS and Navigation systems, digital cameras and Multi Media Players. The CA-301 operates on the quartz crystal principle, where a quartz rod is mechanically cut and connected to two oscillation circuits in order to generate an oscillation signal with extremely precise and stable frequency.
