CDCE913PWR are clock generators, phase-locked loops (PLLs), and frequency synthesizers. It is used to create stable and precise signals for a variety of applications. This article will describe the application field and working principle of CDCE913PWR.

Application Field

CDCE913PWR is designed for a variety of applications. It can be used to create precise clocks for digital applications such as FPGAs and microprocessors, as well as for communications systems, digital audio and video, and medical devices. It can also be used for analog applications such as test and measurement, radio communication systems, radio base stations, and military and aerospace applications.

Working Principle

CDCE913PWR uses a PLL to phase-lock external signals to the synthesizer\'s internal clock or reference. The frequency synthesizer consists of an input reference, a voltage-controlled oscillator (VCO), a loop filter, and a phase-frequency detector (PFD). The reference signal is divided by the reference divider, and the output is provided to the PFD. The output of the VCO is divided by the VCO divider, and this signal is also provided to the PFD. The PFD compares the frequency and phase of the two signals and generates an error signal.

The error signal is used to adjust the frequency of the VCO over time. If the frequencies of the two signals are not equal, the PFD will generate an error signal that will adjust the VCO so that the frequencies will match. The synthesizer is able to operate over a wide range of frequencies. The VCO is designed to provide low-phase noise performance and can be used with a variety of different modulations, such as FM, FSK, PSK, and ASK.

CDCE913PWR can be used to generate a wide range of frequencies, from 1MHz to 2GHz. It can be programmed to various frequency options via programming pins, and it can be modified with software to change the output frequencies. It has an integrated voltage regulator, low-power shutdown mode, and selectable current range.

Conclusion

CDCE913PWR is a versatile frequency synthesizer that can be used in a variety of applications. It uses a PLL and VCO to phase-lock external signals to the synthesizer\'s internal clock. It can be programmed to various frequency options, and it has an integrated voltage regulator, low-power shutdown mode, and selectable current range. It is an ideal choice for creating precise clocks for digital and analog applications.
