Working Principle

PM113-622.08M actually is a voltage-controlled oscillator, where the output frequency is determined by the applied voltage potential. Basically, the oscillator\'s internal circuit consists of several transistors and capacitors connected in series. The capacitor and transistor combination creates an alternating current, that is then converted into a corresponding electrical signal output, with appropriate frequency and voltage amplitude.

When the output frequency needs to be altered, the applied voltage potential is varied accordingly. There is a circuit resistor connected in parallel with the capacitor, which helps to maintain a constant frequency in a wide range of applied voltages. Thus, PM113-622.08M has a very reliable output frequency, with a tolerance as low as 0.2%.

PM113-622.08M also has a high frequency stability, which is maintained in normal working conditions. The oscillator is able to sustain a frequency accuracy within +/- 15ppm over a wide temperature range, from -10℃ to 70℃, with a maximum frequency change rate of 0.3 ppm/℃.
