Oscillators

An oscillator is an electronic circuit that produces a continuous, recurring waveform in the output. Oscillators are used to generate waveforms such as square waves, sine waves and sawtooth waves, as well as more complex shapes and harmonics. The AX7PAF1-77.7600T oscillator is an advanced, low phase-noise PECL (Positive ECL) oscillator that provides a frequency range of 77.7600 MHz to 77.8600 MHz. The AX7PAF1-77.7600T oscillator is a PECL oscillator designed to operate in the frequency range of 77.7600 MHz to 77.8600 MHz. Its comprehensive frequency range allows for use in various applications such as clocks, telecommunications, data communication, wireless local loop, and mobile radio systems. It offers high reliability and low power consumption, and its low phase-noise performance makes it ideal for applications where stable, low-noise signals are required. This oscillator is designed to use External Resonators (XER) for temperature tuning and frequency adjustment. This allows for frequency adjustments over a wider range with better frequency stability compared to quartz crystals. The output signal of the oscillator is CMOS output, which means that it is compatible with professional grade equipment and high performance circuits. The working principle of the AX7PAF1-77.7600T oscillator is simple. It works by using a phase locked loop (PLL) which is used to sample an oscillator signal, create a feedback loop, and then use the feedback loop to control the oscillator’s output frequency. The phase locked loop consists of a phase detector, a voltage controlled oscillator (VCO), and an amplifier. The phase detector monitors the input frequency and output frequency from the oscillator, and if they are not in phase, the phase detector adjusts the output frequency of the VCO to match the input frequency. This ensures that the output frequency of the oscillator matches the input frequency.The AX7PAF1-77.7600T oscillator is a reliable and easy to use oscillator for any application requiring a 77.7600 MHz to 77.8600 MHz frequency signal. Due to its phase-noise performance, low power consumption, and frequency stability over temperature, this oscillator is an excellent choice for those applications requiring a low-noise signal with high reliability.
