Oscillators are electronic circuit components that produce a continuous output signal on the order of tens of MHz. They are used in a broad range of applications and one of the most commonly used oscillators is AX7PAF4-480.0000T. This paper will explain the application field and working principle of this oscillator.

The AX7PAF4-480.0000T is an oscillator that has a 7-bit bipolar digital transmitter, a 250 MHz clock rate and a maximum output power of 1.4 dBm. It is designed for applications such as data communication, RF switching, broadcast, and frequency syntheses. It has a center frequency of 180MHz which makes it ideal for such applications. Additionally, the oscillator has a wide frequency range (120 – 240 MHz) which provides it with great versatility. The device also has a low power consumption (0.45W) allowing it to be used with limited power supply.

As for its working principle, the AX7PAF4-480.0000T utilizes a phase-locked loop (PLL) circuit for frequency control. The PLL circuit starts with a crystal oscillator generating a signal that will be fed to an Input Frequency Divider. This stage controls the incoming frequency by dividing it to the whole N frequencies where N can be any integer number. This signal will then be fed to a phase detector which produces an output that represents the difference of phase between two input signals. The output of the phase detector is then fed to a low-pass filter and a voltage controlled oscillator. The output signal of the voltage controlled oscillator is then fed back to the phase detector and a new output signal is produced. The output of the low-pass filter is fed to the voltage controlled oscillator which makes its output frequency adjust until it is in phase with the input signal. This process ensures that the oscillator locks onto the input frequency and results in a stabilized output signal.

In conclusion, the AX7PAF4-480.0000T is an oscillator that has a 7-bit bipolar digital transmitter, a 250 MHz clock rate, a center frequency of 180MHz, a wide frequency range of 120 – 240MHz, and a low power consumption of 0.45W. It is suitable for applications such as data communication, RF switching, broadcast, and frequency syntheses. It works by utilizing a PLL circuit which locks onto the desired frequency and results in a stabilized output signal.
