The 416F520X2CAT crystal is a specific type of crystal from the Toronto-based firm Canadian Advanced Technology. This crystal is used in the oscillator circuitry of many applications and has become the “go-to” crystal in many products.

Application Field of 416F520X2CAT

The 416F520X2CAT crystal is a very precise low-noise and high-frequency crystal. It is widely used in communication equipment including: wireless transceivers, modems, cell phone base stations, automotive navigation systems, satellite communication systems, MIL-STD-1553 databus transceiver applications, EDACS/LTR transceiver applications, and medical monitoring and imaging equipment.

The 416F520X2CAT has a frequency range of 400 MHz to 520 MHz, and is ideal for harsh mobile environments, as the crystal exhibits excellent temperature and phase-noise performance. It uses a hermetically sealed 5.0x3.2mm ceramic SMD package with extended load capacitors, and its temperature range is from –40ºC up to +85ºC.

Working Principle of 416F520X2CAT

A crystal oscillator is an electronic device that outputs a precise frequency based on the electrical, mechanical or magnetic characteristics of a quartz crystal. The 416F520X2CAT crystal is a Saw-Stabilized resonator that was developed specifically for Radio Frequency (RF) applications. It is a quartz crystal cut into a specific shape, and then mounted to a ceramic substrate and coated with a metal alloy. The 416F520X2CAT uses a coated copper electrode substrate and silver-epoxy back plate, which results in better heat dissipation.

The 416F520X2CAT utilizes hermetically-sealed package technology. This technology extends the load capacitors and provides a low-noise, stable oscillator for applications such as frequency-hopping and spread-spectrum radios. The 416F520X2CAT is an excellent choice for precision RF applications because it utilizes a thin package design which leads to higher mechanical stability and better frequency stability, ensuring error-free transmission of information.

The 416F520X2CAT is designed for operation with low driving levels, excellent frequency stability, and minimal jitter over a wide temperature range. This is achieved due to the combination of advanced metallization techniques, highly integrated digital and voltage controlled crystal oscillator circuits (VCXOs) and optimized digital noise suppression techniques.

Thanks to its hermetically sealed package and thin package design, the 416F520X2CAT has a high degree of thermal and pressure resistance. Its frequency stability over temperature is enhanced by the use of extended load capacitors, which reduce the effects of temperature changes. The 416F520X2CAT has a standard 10 ppm stability, with an option of 15 ppm stability.

Conclusion

The 416F520X2CAT crystal is a highly accurate crystal that is used in a variety of RF applications. Its small package size and hermetically sealed package combine to make the 416F520X2CAT highly resistant to temperature changes and pressure. Its low-noise and high-frequency characteristics ensure reliable and accurate transmission of data in medical, communication, and military applications.
