Working Principle

The 8W-72.000MBD-T oscillator utilizes a VCO (voltage-controlled oscillator) core with an integrated reference oscillator. The oscillator is designed with a low-voltage, wide-input-voltage operation. It is temperature-compensated and features low phase noise and very low jitter.

The 8W-72.000MBD-T oscillator works on the principle of negative resistance. It uses an integrated circuit comprising two resistors in series and three active devices in parallel. The active devices act as current amplifiers, with the common output being connected to the second resistor, thus forming a negative feedback loop. The circuit includes a series capacitor connected to the negative input of the transistor. The voltage between the first resistor and the common output is regulated to ensure a constant output frequency.

When the input voltage to the transistor increases, the transistor behaves as a negative resistance, and the output frequency decreases. Conversely, when the input voltage decreases, the transistor behaves as a positive resistance, and the output frequency increases. The 8W-72.000MBD-T oscillator also features low phase noise and low jitter, making it suitable for use in a wide variety of applications.
