Working Principle of the DSC400-0111Q0117KI2T

The DSC400-0111Q0117KI2T is a half-synthesizer/half-PLL oscillator, with a base oscillator in the centre of the device. The PLL (Phase Locked Loop) is used for higher frequency synthesis and is configured through an external host controller. It then divides the frequency of a reference signal by a factor of 4 and sends the divided signal to the base oscillator.

The base oscillator has a wide range of frequency ranges from 11.001 MHz to 400.000000 MHz with a typical frequency accuracy of ±25 ppm at calibrated temperature conditions of 25 °C. It also support 16 different clock outputs, including four different LVCMOS options, four different LVDS options, four different CMOS/CML options, and four different LVPECL options.

The base oscillator covers a wide range of frequency coefficients and includes an all-digital phase-locked loop and frequency synthesizer, providing an efficient and complete solution for clock signal conversion.

In addition, the DSC400-0111Q0117KI2T supports pin programming for power-up/power-down (3-state outputs) and phase-lock disable (4-state outputs). It is designed for low-power operation, consuming only 80mA of current in typical operation.

Conclusion

The DSC400-0111Q0117KI2T is a highly versatile, low-power pin configurable/selectable oscillator that is suitable for a wide range of applications, such as communication and networking. It is a powerful device, providing excellent stability, low jitter, and low phase noise, as well as offering a wide range of output options. In summary, the DSC400-0111Q0117KI2T is an excellent oscillator device, providing an ideal solution for applications requiring a high level of performance and stability.
