Oscillators

An oscillator is an electronic circuit used to produce a repetitive signal (usually a sine, square, or sawtooth wave) at a certain frequency, typically determined by an external or internal resistor and capacitor values. Commonly used for timing, clock, and waveform generation, oscillators are used to generate signals that can be used to generate sound, control the power of an amplifier, or transmit radio waves.The AX7DBF4-100.0000C model of oscillator is a low power, high frequency device, designed for many different applications. It utilizes a bulk acoustic wave (BAW) resonator, manufactured using proprietary technology. The surface acoustic wave (SAW) resonator technology provides superior frequency stability over the temperature range, and is typically used in applications requiring low frequency crystal oscillator and extended temperature range.

Features

The AX7DBF4-100.0000C has a number of features that provide superior performance and flexibility. It features a low start-up time of less than 400µs, a wide supply voltage range of up to 17V, low power consumption, low jitter and excellent frequency stability over the temperature range. Additionally, it features an improved output isolation of typically > 45dB, an improved center frequency accuracy of +/-1.25 ppm over the temperature range, the ability to operate at frequencies as low as 32 kHz and as high as 100 MHz, and a robust package with two-side anchoring.

Applications

The AX7DBF4-100.0000C is ideal for applications requiring low power consumption, accurate frequency stability, and ultra-low jitter. Common applications include telecom, active antennas, medical implants, industrial, automotive, instrumentation, and consumer electronics.

Working Principle

The AX7DBF4-100.0000C oscillator is based on a robust BAW resonator, which consists of two electrodes separated by low-loss dielectric material. By applying an alternating current (AC) voltage to the resonator, a mechanical wave is created which is able to vibrate the resonator at a set frequency.The frequency is determined both by the applied voltage and the thickness of the dielectric material. The main electrical ports of the resonator are connected to a tank circuit, consisting of an inductor and a capacitor, forming a resonant parallel circuit. This circuit further increases the overall frequency stability of the oscillator, as well as providing adjustable frequency control.

Conclusion

The AX7DBF4-100.0000C is a reliable, robust, low power, and high frequency oscillator designed for ease of use and superior performance in a variety of applications. Its advanced BAW resonator technology results in improved frequency stability over the temperature range, low power consumption, and an improved output isolation. The AX7DBF4-100.0000C is ideal for a wide range of applications including telecom, active antennas, medical implants, industrial, automotive, instrumentation, and consumer electronics.
