Crystals – ABLS7M-20.000MHZ-B-2-T application field and working principle

Crystals are widely used in many electronic and timekeeping devices, as oscillators for providing highly precise, consistent timing. One instance of a crystal is the ABLS7M-20.000MHZ-B-2-T – a miniature SMD crystal oscillator. This section will discuss the application field and working principle of this crystal.

Application field

The ABLS7M-20.000MHZ-B-2-T is a miniature SMD quartz crystal oscillator for frequency control and timing applications operating in the 20MHz range. The temperature compensated crystal oscillator (TCXO) uses an athermal oven that’s able to achieve an industry-leading reference frequency stability over temperature. It is a hybrid-mode frequency, which means it can be used in many different systems.

The ABLS7M-20.000MHZ-B-2-T crystal can be used in a variety of fields, such as wireless communications, such as GSM, CDMA, WCDMA; digital broadcasting, wireless modules, GPS systems, LBS (location based services), digital TV and satellite TV, phones, and portable media devices, such as USB data clocks and media players.

Working principle

A quartz crystal works by vibrating and resonating when an electrical current is applied. This creates a consistent clock signal with a highly precise frequency. This is achieved by using the properties of piezoelectricity, which allows quartz crystals to be pushed or pulled and generate an electrical charge in the process.

The ABLS7M-20.000MHZ-B-2-T oscillator has higher frequency stability than other clocks, owing to its built-in temperature compensating layer. The oscillator is designed with two layers: the quartz crystal and a temperature compensating layer. The oscillator works as follows:

The quartz crystal is made up of a regular array of atoms, which cause a specific frequency pattern when they vibrate. The temperature compensating layer is designed to expand and contract with temperature changes, which ensures that the frequency remains consistent. When a clock system is operating at one temperature, the temperature compensating layer is designed to adjust the frequency accordingly, ensuring the oscillator is able to remain within a few parts per billion of the desired frequency.

The ABLS7M-20.000MHZ-B-2-T oscillator is a miniature SMD variation, meaning that it is small enough for use in many applications. The oscillator works in a wide range of temperatures, from -40°C to 85°C, and is characterized for 10% to 90% humidity operations. The ABLS7M-20.000MHZ-B-2-T is a highly reliable crystal, and is often used in many consumer and industrial applications.

Conclusion

The ABLS7M-20.000MHZ-B-2-T miniature SMD quartz crystal oscillator is a reliable and widely used type of crystal with high frequency stability. It can be used in many applications, such as wireless communication systems, digital broadcasting, GPS systems, digital TV, and media devices. The crystal works by using the properties of piezoelection and a built-in temperature compensating layer, ensuring that it is able to remain within a few parts per billion of the desired frequency.
