FA-238 40.0000MB-K3

Crystals are used as an energy source for many applications, and the FA-238 40.0000MB-K3 is one such example. The FA-238 is a crystal quartz oscillator that is designed to provide extremely precise time and frequency control. The FA-238 crystal is made of a thin cut quartz wafer that has been precisely aligned and housed in a metal case. This enables the crystal to provide a stable and reliable frequency output.The FA-238 crystal is a temperature-compensated oscillator (TCO) as well as a voltage-controlled crystal oscillator (VCXO). The quartz material used in the FA-238 is selected to provide the most stable frequency over a wide temperature range. It also has low phase noise, which helps reduce interference. It can be used in high-frequency communication applications such as automotive, aerospace, consumer electronics, and industrial applications.The FA-238 crystal can be used in the following applications:

• Oscillator for spread spectrum telecommunication.
• Timing reference for GPRS and CDMA systems.
• High frequency clocks for wireless communication.
• Data rate stabilization for wireless LAN.
• Precision-controlled oscillator for telecom.
• Oscillator for guidance systems.
• Oscillator for antenna speakers and car audio systems.

The working principle of the FA-238 crystal is based on a specialized oscillator circuit and vibration of the quartz crystal. The oscillator circuit converts the electrical signal into an oscillating signal. This oscillating signal is then amplified and reinforced using the quartz crystal material.The FA-238 crystal is composed of a quartz wafer that is aligned and held in place with a metal casing. This casing also serves as a holder for the crystal that helps protect it from mechanical shock and other external influences. The quartz material is carefully selected to provide the desired frequencies and stability.The operating frequency of the FA-238 crystal is determined by the specific resonant frequency of the quartz material. In order to adjust the frequency, the quartz wafer is finely tuned to the desired frequency. This process is called frequency trimming, and is accomplished by adjusting the frequency with a special trim-pot.The FA-238 crystal oscillator provides extremely precise, low jitter and low phase noise performance. It is accurate within 10 ppm (parts per million) and is ideal for applications that require high stability and repeatability. The FA-238 can operate over a wide temperature range, is immune to aging, and is easy to install and maintain.In conclusion, the FA-238 40.0000MB-K3 crystal oscillator provides high-precision and low-jitter frequency control. It is ideal for applications such as spread spectrum transmission, GPRS and CDMA systems, wireless communications, and precision-controlled oscillators. The quartz material is selected to provide excellent frequency stability, while the metal casing helps protect the crystal from external influences. The crystal is also accurate within 10 ppm, making it suitable for many demanding applications.
