The working principle of ECX-H33CM-250.000 oscillator is based on the negative resistance properties of a semiconductor diode, which allows an oscillator to produce a stable frequency signal. The diode is typically combined with a resistor and capacitor, forming a negative-resistance oscillator or “LC oscillator.” It uses the weak capacitive coupling of the the capacitor and resistor to create a regenerative feedback loop that alternates between charging and discharging the capacitor. This creates an oscillating voltage waveform across the capacitor, and with the appropriate components, a sine wave is produced.

The signal amplitude of the sine wave is typically controlled by the bias current of the diode or by adding an additional resistor or diode to the circuit. The frequency is also controlled by the values of the capacitor and resistor in the LC oscillator. The combination of these components allows the user to adjust the frequency and amplitude of the output signal.

In conclusion, the ECX-H33CM-250.000 oscillator is a versatile and reliable component, suitable for a variety of applications. It has a wide frequency range, low phase noise, and a high precision frequency accuracy, making it an ideal reference frequency source for many digital systems.
