512CCA000174BAG

The 512CCA000174BAG is part of the Pin Configurable/Selectable Oscillators category. It is a 21.47 MHz Crystal stabilised Oscillator in a RoHS compliant 3 mm x 3 mm SMD plastic package. As part of this category it has a wide range of applications due to its capability to be tuned to different frequencies based on the configuration of external circuitry.

Also, due to its layout, this device comes with a maximum operating temperature of 85°C along with a robust design ideal for a variety of environments. Therefore, the 512CCA000174BAG is particularly suitable for electronic manufacturing, medical equipment and mobile systems.

When talking about its working principle, it is based on the quartz crystal resonator which works on the principle of piezoelectricity. At its most elementary level, the quartz crystal resonator consists of two parallel plates of quartz with electrodes on either side which when a voltage is applied, cause the quartz plate to vibrate. The resonator has a natural resonance at a particular frequency, determined by its size and shape, and will be output as either a time-varying voltage or current.

The 512CCA000174BAG combines this idea with a two-stage amplifier, a frequency-selective feedback path and a timing capacitor to produce a stabilized oscillator. The two amplifiers within the oscillator amplify the output of the crystal, while the frequency-selective feedback and timing capacitor control the frequency of oscillation. By allowing the user to select the frequency of oscillation and adjust the timing capacitor, the 512CCA000174BAG can produce either a multi-frequency signal or a signal that remains at a constant frequency.

Overall, the 512CCA000174BAG is a reliable and highly accurate Pin Configurable/Selectable Oscillator, ideal for a variety of important applications such as with electronic manufacturing, medical equipment and mobile systems due to its robust design and ability to be tuned to different frequencies. Its working principle centres around the quartz crystal resonator and a two-stage amplifier, a frequency-selective feedback path and a timing capacitor to create its functioning.
