Working Principle

The TD-76.800MBD-T oscillator is based on a quartz crystal resonator and relies on the resonant frequency of the crystal to determine its frequency. The quartz crystal resonator consists of two conductive plates, each containing quartz crystals, connected to a conductive rod. The quartz crystals vibrate at a frequency determined by the resonant frequency of the crystal, which is then used to control the frequency of the oscillator.

At the heart of the oscillator is a tunnel diode, which is a semiconductor device that acts as a switch. The tunnel diode has a depletion region, which can be used to control the amount of current flowing through it. The tunnel diode is connected to the quartz crystal resonator, and the resonant frequency of the crystal is used to determine the frequency of the oscillator.

The tunnel diode and quartz crystal resonator work together to create a closed-loop control system. As the frequency of the oscillator changes, the tunnel diode adjusts the current it is supplying to the crystal, which in turn adjusts the frequency of the oscillator. This allows the oscillator to maintain an extremely accurate frequency control, even in challenging conditions.
