  • Thank You for fast reply! I use IC5.1.41 and MMSIM7.2. Are there any alternative ways of pll analysis? And could you please explain how to define an LPF? Could it be extracted in the same manner as VCO or PFD-CP? I understood it's no longer supported but for educational purpose it would be a good example of using behavioural models .
