A CDCVF2510APWRG4 is a Clock/Timing signal generator specifically a frequency synthesizer. It is a single-chip frequency control solution for implementations requiring low jitter, low system cost applications. This signal generator is designed to support a wide range of applications from frequency generation, signal sharing and signal distribution.

This signal generator belongs to the family of CDCVF25xx clock/timing signal generators, integrating features and functionality that provide a level of system integration never before seen in a signal generator of its kind.

The frequency of the signal is programmable up to 400 MHz with a resolution of 1 MHz and a frequency accuracy of +/- 0.08 %. The device includes a number of features such as a variable duty cycle mode, phase-locked loop (PLL) function, an adjustable output spread spectrum, an open-drain output, a digital phase shifter, a debounce filter and an I²C bus interface.

The CDCVF2510APWRG4 primarily caters for applications that require a high degree of precision and repeatability in frequency generation and sharing. Examples include wireless networks, synchronous data transfer, wireless communication systems, point-to-point applications, timing distribution, image scanning and encoding, clock distribution and other similar applications.

The working principle of this frequency synthesizer is based on a digitally controlled oscillator, which is composed of a new phase-locked loop (PLL) design. The system clock of this oscillator is sweeping from a start frequency to a stop frequency. Meanwhile, it is going through a phase alignment process to achieve a phase-locked condition. Once this phase alignment occurs, the PLL output frequency is determined. This PLL can accomplish a 1 MHz to 400 MHz within a lock time of a few microseconds.

The CDCVF2510APWRG4 is equipped with a number of features that simplify design and reduce system costs. These include an I²C bus interface and an adjustable output spread spectrum to reduce EM emissions. An open-drain output allows the use of an external load circuit, while a digital phase shifter provides an easy-to-implement phase control solution and a frequency selection with a resolution of 1 MHz. Furthermore, the adjustable duty cycle mode and debounce filter enable precise and repeatable frequency generation out of the box.

In summary, the CDCVF2510APWRG4 is a versatile frequency synthesizer suitable for a variety of applications such as wireless networks, synchronous data transfer, image scanning and encoding, clock distribution and other similar applications. It is capable of generating a precise and repeatable signal with a dynamic frequency range up to 400 MHz. With its focus on reliability and system cost savings the CDCVF2510APWRG4 is an ideal choice for implementing cost-effective solutions requiring precise and repeatable frequency generation.
