PRODUCTION DATA.
The design of the loop filter is complex and is typically done with software. The PLLatinum Sim software is an excellent resource for doing this and the design is shown in the following figure. For those interested in the equations involved, the PLL Performance, Simulation, and Design Handbook listed in the end of this document goes into great detail as to theory and design of PLL loop filters. PLLatinum Sim does not model the mixers and LNAs in this device, but it can be used for the PLL. To use this tool, it can be modeled as the LMX2594 PLL.
