ASTMHTFL-80.000MHZ-XR-E-T

Oscillators are generally used in circuits where an output signal has to be generated at a specified frequency. One such oscillator is the ASTMHTFL-80.000MHz-XR-E-T, a precision quartz crystal clock oscillator capable of operation over a wide temperature range of -40°C to +85°C. It is mainly applicable in embedded applications including mobile phones, PDAs, digital cameras and other consumer electronics.

Overview

The ASTMHTFL-80.000MHz-XR-E-T is a complete quartz crystal clock oscillator package developed on the basis of the XTAL-integrated monolithic crystal circuit. By combining the quartz crystal along with associated components in a small package, the device provides superior frequency accuracy, superior temperature stability, and excellent shock and vibration capability. Its package dimensions are 1.3mm x 1.9mm x 0.85mm, which makes it very suitable for high frequency and space-critical applications.

Features and Benefits

The ASTMHTFL-80.000MHz-XR-E-T offers an extensive range of features and benefits to its users. Firstly, it is designed to operate over a wide temperature range of -40°C to +85°C and offers excellent temperature stability. Furthermore, it offers superb frequency accuracy, with typcial drift of a few parts per million (ppm) across the temperature range. Additionally, it supports operation up to 1.9V and is consequently suitable for powering most low-power devices.

Applications and Working Principle

Due to its small package and wide temperature range, the ASTMHTFL-80.000MHz-XR-E-T is widely applicable in embedded applications including mobile phones, PDAs, digital cameras and other consumer electronics.

The working principle of the ASTMHTFL-80.000MHz-XR-E-T is based on a quartz crystal circuit. The quartz crystal resonator, connected to the XTAL connectors, oscillates between an upper limit frequency and a lower limit frequency, depending on the environmental conditions. The interval between the two limits can be fine-tuned by injecting a charge to the quartz crystal via the Trim Cap. This will cause a change in the capacitance and, consequently, the resonant frequency.

Conclusion

The ASTMHTFL-80.000MHz-XR-E-T precision quartz clock oscillator is an ideal solution for embedded applications, offering high frequency accuracy, wide temperature range and superior shock and vibration capabilities. By using a quartz crystal and a trim cap, it offers flexibility, stability and accuracy even in the harshest of environments.
