Fractional PLL is used when you want to generate a uncommon clock frequencies with fractional numbers such as 6.625Mhz, 3.125Mhz etc clock frequency. Integer PLL is used when you want to generate a common clock frequencies like 10Mhz, 25Mhz, 125Mhz etc. how to use and...

A digital fractional PLL introduces an accumulated phase offset before the digital VCO to achieve the fractional part of the division ratio. To provide this phase offset, the digital accumulator can integrate a fractional component 螖n. By forcing 螖n to zero, the PLL becomes an integer-N PLL...

pPLL03F can be used as an integer-N PLL or as a fractional-N PLL. The fractional-N mode provides a high flexibility to choose the best combination of input and output clock frequencies at the system level. Perceptia further provides integration support and offers customization and migration ser...
1.4.2 Fractional Operation and Spurious Unlike an integer PLL, spurious signals in a fractional PLL can occur due to the fact that the VCO operates at frequencies unrelated to the PD frequency. Hence intermodulation of the VCO and the PD harmonics can cause spurious sidebands. Spurious emissions...

The DTC-based fractional-N divider in the digital PLL with a single-bit TDC can be realized as shown in Figure 5.20. The classical digital ΔΣ modulator generates the signal dithering the modulus of the integer-N divider between N and (N + 1). The large quantization error produced by th...
