The DSC1101CI1-148.5000 has an output frequency range from 10kHz to 150MHz and can be configured for both single-ended and differential outputs.

Working Principle

The DSC1101CI1-148.5000 oscillator operates on the principle of a voltage-controlled oscillator (VCO). This type of oscillator utilizes an external voltage to modulate the frequency of the oscillator output. To achieve this control, the oscillator typically incorporates an integrated crystal oscillator (XO), which is connected to a frequency divider (FD) and a phase-locked loop (PLL).

The crystal oscillator uses an external quartz crystal to facilitate oscillation. This crystal acts like a spring that is moved back and forth by an electrical current. When the current passes through the crystal, it causes the crystal to vibrate and produce an electrical signal. This signal is then fed into the frequency divider which reduces the frequency of the signal and sends it to the phase-locked loop (PLL).

The PLL uses a voltage-controlled oscillator to compare the frequency of the input signal from the frequency divider with the amount of voltage applied to the oscillator. The PLL is then able to modify the frequency of the output signal by adjusting the amount of voltage applied to the oscillator. The result is a periodic signal that is modulated by the voltage applied to the oscillator and can be accurately controlled over a wide range of frequencies.

Conclusion

In conclusion, the DSC1101CI1-148.5000 oscillator is a voltage-controlled oscillator (VCO) that utilizes a combination of an integrated crystal oscillator (XO), a frequency divider (FD), and a phase-locked loop (PLL) to achieve its low phase noise, high performance, wide frequency range, and low jitter characteristics. This makes the oscillator the perfect choice for high-resolution data acquisition boards and other precision measurement applications.
