Working Principle

The EG-2101CA 312.5000M-PCHL0 oscillator works by converting a digital/analog signal into a continuous sine wave with an exact frequency. The frequency is divided by the output frequency divider to create 32 synchronized outputs. The process begins with an input signal, converted into a sinusoidal signal by a narrow-band voltage-controlled oscillator (VCO). The input frequency is then digitally divided and calibrated by a digital/analog converter. The output of the converter is then connected to a Σ/Δ modulator, which reduces frequency variation within the output signal.

The signal is then amplified through a 7-state amplifier, which increases the amplitude of the output signal. Finally, the amplified signal is combined with another, weaker signal from the output of the frequency divider. As the two signals are combined, they form a single, more-stable signal with an exact frequency. This output signal is then transmitted through an RF filter, to ensure the output noise is within the required limits.

Conclusion

The EG-2101CA 312.5000M-PCHL0 oscillator is an advanced device designed to provide superior accuracy and performance. Its combination of digital and analog control allows for precise frequency control over a wide range of applications. Its ability to accept different types of input signals and to reduce frequency variability make it an ideal choice for use in communication systems, laboratory measurements, and many other applications.
