A charge pump PLL is a popular way to design a PLL. It is a good idea to analyze its requirements and relate the design to those parameters even before the functional blocks are designed. This provides the design engineer a pathway to complete the design from behavioral modeling to a final semiconductor layout to be fabricated. The higher level analysis can be done very quickly and lays bare the techniques, risks, timelines etc. for the design. A recent whitepaper by Signal Processing Group Inc. presents these assessments.
