Oscillators are electronic circuit components that can produce an output signal with certain frequency, amplitude and waveform even without any external input. A popular example of oscillator is the DSC1123DI2-125.0000. This type of oscillator generates sinusoidal waveforms over the frequency range of 8 MHz to 125 MHz, making it ideal for different types of applications.
Application Field of DSC1123DI2-125.0000
Among all oscillators, the DSC1123DI2-125.0000 can be used in a wide range of applications. It can be used for radio transmission, radio reception, clock pulse generation, and pulse repetition. In telecommunications, this oscillator can be used for modulation, demodulation and frequency tuning. Moreover, it is ideal for frequency synthesis, frequency division, frequency control and timing circuit.
Working Principle of DSC1123DI2-125.0000
DSC1123DI2-125.0000 has a Pierce-type oscillator circuit which employs two transistors (usually FETs) in a cascade configuration. The first transistor, Q1, is usually a voltage-controlled device, and the second, Q2, is a current-controlled device. This oscillator requires feedback and operates based on the principle of positive feedback. This means that the output signal of Q2 is fed-back to the input of Q1, amplifying the input voltage to give rise to oscillatory behavior.
The frequency of the oscillator is determined by the traditional Colpitts oscillator formula that requires two capacitors and an inductor in the feedback circuit. The two capacitors, C1 and C2, decide the frequency of the oscillations as they cause a frequency-dependent phase shift. C1 should be a fixed capacitor while C2 should be a variable capacitor in order to control the frequency.
To ensure a stable output signal, the damping ratio of the feedback loop is determined by the resistors R1 and R2. Impedance imbalance between the two transistors is prevented by adjusting both their biasing conditions. The voltage gain determined by R1 and R2 should be kept high enough to ensure oscillations while avoiding engine-like oscillations.
Conclusion
DSC1123DI2-125.0000 is a high frequency oscillator of Pierce-type consisting of two transistors. It can produce highly stable sinusoidal waveforms over the frequency range of 8 MHz to 125 MHz. It is very versatile, and can be used in a wide range of applications such as radio transmission, clock pulse generation, frequency synthesis and timing circuit.
