Oscillators

An oscillator is a device that generates a close-range or repetitive electronic, electrical or acoustic waveform that is often periodic. This oscillation can be a stable, repeated pattern or a timestamped output, such as a periodic clock signal. Oscillators can be used for a wide range of applications, such as supplying current to a motor, powering microphone transmissions, generating tone signals for intercom systems, producing low-power GPS signals and in medical imaging machines.The FXTC-HE73PR-16.67 MHz oscillator is an example of a crystal oscillator, which is a type of oscillator that uses a quartz crystal to produce a set of stable electrical signals. This type of oscillator is commonly used where highly accurate frequency output is required over a wide range of temperature conditions. This oscillator is designed to provide a reliable and highly accurate signal with minimal phase noise; it features an RF output connector, a frequency synthesis/LOCK detector pin and a VCO/LOCK detector pin.The working principle of a crystal oscillator is based on the piezoelectric effect, where a voltage is applied to a quartz crystal, inducing a mechanical strain on the crystal. The resulting mechanical stress changes the crystal’s physical condition, causing it to vibrate. This vibration is translated into a waveform and subsequently amplified and converted to an electrical signal. In order for a crystal oscillator to remain stable, the crystal must be constructed so that the desired frequency can be achieved. This is done by constraining the surface area of the crystal to a certain shape while maintaining the closest possible packing of ions in the lattice. This creates a lattice structure that has a natural resonant frequency, referred to as the oscillator’s fundamental frequency. The oscillator’s frequency can be adjusted by the addition of a small capacitor or inductor, which are also known as frequency-adjusting elements. By adjusting the capacitance or inductance, the oscillator’s output frequency can be adjusted by a few kilohertz up or down. In order to maintain stability, these adjustment elements must be adjusted with precision to the oscillator’s fundamental frequency.The FXTC-HE73PR-16.67 MHz oscillator has an operating temperature range between -30°C and +85°C and a supply voltage range of 4.75 volts to 5.25 volts. It is designed to operate within this temperature range and supply voltage range and to maintain stability and long-term accuracy within a frequency tolerance of +15/-15 ppm.The FXTC-HE73PR-16.67 MHz oscillator is suitable for a variety of applications, such as GPS receivers, medical devices, telecom systems, audio systems, RF test equipment and power supplies. It is a reliable and highly accurate source of frequency output with minimal phase noise, making it an ideal choice for a wide range of applications that require a stable frequency output.
