Application Field

445C25B24M57600 crystals are bipolar, monolithic, surface-mounted components with increased operating temperature, +/- 10-30ppm stability, selectable operating voltage, and low power consumption, making them suitable for a wide range of applications. These crystals are especially useful in integrated circuit (IC) applications, where their small size and high-performance characteristics can be particularly advantageous.

The device has four pins which are rated +ve, -ve, input, and output. It requires low cost printed circuit boards (PCBs) and associated components to be used in applications where small board footprints are desired. In addition, the device can be connected directly to a microcontroller or digital signal processor (DSP) with minimum fuss.

The 445C25B24M57600 crystal can be used in applications including:

• Radio Frequency (RF) transceiver circuits
• Communications systems
• Digital Timing Control
• Various frequency-based Digital Control Systems
• Embedded microcontroller systems
• System clocks

Working Principle

445C25B24M57600 crystals use an internal quartz crystal element to oscillate at a stable frequency. The device is also designed to buffer the quartz crystal and provide voltage regulation. When an AC voltage of an appropriate magnitude is applied across the device terminals, quartz crystals within the device resonate, generating a continuous output signal. This signal is then used to drive a circuit such as a microcontroller or radio frequency (RF) transmitter.

The output signal is of a sine wave shape and the frequency of the output signal is dependent on the mass and dimensions of the quartz crystal element. The higher the mass and dimensions of the quartz crystal, the higher the frequency of the output signal. For example, a device such as the 445C25B24M57600 is designed to produce an output signal in the range of 24MHz, which can be used to drive discrete components and integrated circuits.

The crystal also features Electronic Frequency Control (EFC) which adjusts the frequency of the output signal in response to changes in the external environment. This is done by varying the applied voltage to the crystal, which produces small changes in frequency of the output signal. This allows the device to be used in applications where environmental conditions may vary, such as automotive or industrial systems.

Conclusion

The 445C25B24M57600 crystal is a compact, low-cost component that can be used for a wide range of applications. It offers superior stability, low jitter, and low power consumption with the added benefit of Electronic Frequency Control which allows the device to be used in applications where environmental conditions may vary.
