Oscillators are automatic electronic circuits that maintain a steady frequency on its output. The AX7DCF1-166.0000T oscillator is a fractional-N PLL (phase-locked loop) clock generator, which is used for its versatile range of applications and working principles.The oscillator module comprises a set of components like the Vctcxo (Voltage Controlled Temperature Compensated Crystal Oscillator), a phase-frequency detector (PFD), a charge pump, a low pass filter (LPF) and a Voltage Controlled Oscillator (VCO, also called a Voltage Controlled Crystal Oscillator, VCXO). Additionally, a temperature sensor and a memory are often included in the module. The VCTCXO serving as the input of the oscillator is used to measure the frequency of the oscillator output with a precision of a few parts per million. This input is connected to the PFD, which in turn, compares the actual frequency with the frequency described in the memory. From there, the output of the PFD is connected to the Charge pump, which increases or decreases the operating current of the Voltage Controlled Oscillator (VCO) based on the output of the PFD. The Voltage Controlled Oscillator (VCO) output is then fed to the Low-pass Filter (LPF), which is used to average the frequency and allow for the phase-locked loop to circulate. The filtered output of the LPF is then fed back to the input of the PFD, and the cycle is repeated. Thus the output of the oscillator stays at the desired frequency. The temperature sensor is used to keep the output frequency of the oscillator constant even if the ambient temperature changes.The AX7DCF1-166.0000T oscillator is capable of providing a wide range of output frequencies. Its operating range extends from 10 KHz to 10 MHz, allowing it to be used in a variety of applications. It is also highly stable and provides high-accuracy precision, making it suitable for high-precision applications like communication systems, data logging and positioning.The oscillator is also known for its low power consumption, which makes it ideal for battery operated and portable devices. It has a frequency accuracy of 0.8 parts per million (ppm) and offers high stability with an aging coefficient of 0.2 ppm/year.In summary, the AX7DCF1-166.0000T oscillator is an ideal choice for a wide range of applications. Its versatile range of operating frequencies, precision, and stability make it suitable for high performance and critical applications. In addition, its low power consumption makes it ideal for use in battery-powered and portable devices.
