08/30/2011 - updated trail version of latest tool, now supporting both active and passive loop filter, and including Win-7. Click on link below, download, rename from .txt to .exe and execute.
This tool allows to design a PLL loop filter. The tool can suggest RC component selection based on the PLL configuration and target performance or calculate loop filter behavior based on the RC component selection. The tool also plots loop filter gain (closed loop, open loop) and phase margin.
I have a customer that is running Win 7 that could not get this to install, returning an error "INI file could not be loaded properly". I attempted to install on Win 7 x64 and received the same error.
