Crystals are universally utilized in many electronic gadgets today and they are used to not only produce accurate oscillations of frequency, but also as frequency selectivity element. Depending on the type of application needed, crystals are available in a variety of rise and fall time characteristics, input capacitance, operating temperature and frequency accuracy. One such form of crystals gaining so much attention in electronics field is AV-13.560MDHE-T.

The AV-13.560MDHE-T crystal, manufactured by Abracon, is a 13.560 MHz, low profile, low operating current, high frequency fundamental mode, surface mount, Lead Free and RoHS compliant crystal. It features a maximum frequency pullability of +/- 5 ppm, an extremely tight frequency tolerance as low as +/- 10 ppm, an operating temperature range from -10°C to +60°C and a storage temperature range from -20°C to +70°C. It also has a fast rise/fall time of 40/15, relatively low ESR and an extremely low operating current of 10.7 mA max at 10 kHz. This crystal is widely employed as oscillator element in microcontrollers and other electronic gadgets like electronic watches, mobile devices and medical devices that require high frequency accuracy.

The way AV-13.560MDHE-T crystal produces the specific frequency is all the same. It operates on the piezoelectric effect, effectively producing a voltage at its terminals when a mechanical distortion is induced on its surface. This voltage is mathematically linked to the frequency of the crystal. However, the fundamental mode crystal in this model has a higher frequency compared to other crystal modes like the higher overtone crystal. As the name implies, the fundamental crystal operates at the fundamental frequency and is usually used for applications like frequency uncertainties and reference clocks.

Considering its crystal size, accuracy and versatility, the AV-13.560MDHE-T is easily one of the most highly recommended fundamental mode crystals in the market today. It is used in radio frequency interference filters, millimetric bands, broadcast receivers, wireless base stations and most of the microcontrollers and embedded applications. An important thing to note is that higher frequencies also demands higher stability, which is precisely why this model can handle many of the high frequency applications with much accuracy and trust. Additionally, it also offers a great level of stability when frequency ranges surpass 500 MHz.

To get the best performance from an AV-13.560MDHE-T crystal, it is essential that the PCB layout is designed to reduce thermal resistance and maximize the thermal efficiency of the device. For example, using Johnson’s Effect for energy management can help maintain the device’s stability. The crystal also should be enclosed in thermal material in order to further reduce the temperature differences. Furthermore, it is important to perform regular calibrations in order to keep track of its frequency stability.

In summary, AV-13.560MDHE-T crystals are widely employed in many of the recent electronic gadgets and they are rather reliable in maintaining its stability and accuracy. It is relatively easy to design board layout and thermal envelops to minimize its temperature dependency. Accurate calibration and regular testing are highly recommended in order to get the best performance out of this crystal. So, anyone looking for an oscillator element for their electronics projects can definitely consider this model.
