NA-10M-6835 application field and working principle

NA-10M-6835 has been a widely used reference oscillator in past decades. It is mainly used in data buses of digital systems, frequency synthesis, RF signal sources, phase locked loops, frequency multipliers, microprocessor systems, navigation systems, digital telecommunication applications, sonar and radar systems and so on. This particular oscillator features a long life-expectancy, a 5 ppm frequency stability and excellent shock resistance and vibration resistance.

Generally speaking, the working principle of the NA-10M-6835 oscillator involves a mechanical resonator which provides the basic reference frequency and an amplifier in a voltage feedback loop. The loop is then used to sense and amplify any variations in the output frequency. The mechanical oscillator works by continuously changing its own effective capacitance and impedance on every cycle, which, in turn, is re-transformed and fed back to generate its own output. This process then leads to the generation of sine waves.

The output frequency of the oscillator is determined by the reactive and resistive elements of its LC load. The linear resonator in the oscillator generates a positive, zero, or negative resistance. This then changes the effective load on each cycle, enabling it to generate its own output frequency. Additionally, the oscillator also employs a quartz crystal and a JFET (junction field effect transistor) in order to maintain its stability.

In summary, the NA-10M-6835 oscillator is an excellent choice for frequency sources due to its long life-expectancy, 5 ppm frequency stability, and good shock resistance and vibration resistance. Its working principle involves a combination of a mechanical resonator, an amplifier in a voltage feedback loop, and also a quartz crystal and JFET which are used to maintain its stability.
