Working principle

ASTMLPV-125.000MHZ-LJ-E-T3 is based on a phase-lock-loop (PLL) principle. It utilizes an electronic feedback loop to adjust the oscillation frequency. This feedback loop consists of three components: an oscillator, a filter, and a voltage-controlled amplifier (VCA).The oscillator generates a signal which is then filtered by the filter. The filtered signal is then amplified by the VCA. The output of the amplifier is fed back into the oscillator, where it acts as a reference signal.The oscillator adjusts its frequency based on the reference signal, and the VCA adjusts the amplitude of the resulting signal based on the amplitude of the reference signal. This ensures that the resulting signal is at the desired frequency and amplitude.In summary, ASTMLPV-125.000MHZ-LJ-E-T3 is a highly reliable and stable oscillator designed for use in various applications. It is based on a PLL principle and utilizes an electronic feedback loop to adjust the oscillation frequency and amplification of the signal. This ensures that the resulting signal is at the desired frequency and amplitude.
