Working Principle

The CDCEL925PWRG4 contains two separate sections; a clock generator and a phase-locked loop (PLL) frequency synthesizer.The clock generating section includes a differential crystal oscillator and digital phase locked loop (DPLL) clock multipliers and dividers, while the PLL consists of a voltage-controlled oscillator (VCO) and a set of dividers and multiplier stages. The PLL is used to generate multiple clock signals with a fixed relationship to the crystal oscillator and is adjustable using an external voltage control input (VCONTROL).The combination of the crystal oscillator, clock multipliers and dividers, and adjustable PLL allows the CDCEL925PWRG4 to generate multiple, adjustable clock signals with a wide range of frequencies, phase alignment and duty cycles from a single crystal oscillator reference. This makes the IC an excellent choice for systems with frequency reference accuracy and stability requirements.

Conclusion

The CDCEL925PWRG4 is a highly versatile clock generator, phase-locked loop (PLL) and frequency synthesizer from CTS Electronic Components. This IC is well suited for use in a variety of discrete, digital and RF systems, with applications in telecom, automotive, industrial and audio-video equipment. Its combination of clock generator, clock multipliers, divider, and adjustable PLL allow it to produce multiple timing signals with frequency reference accuracy and stability.
