Not sure; I've never used any SPICE other than LTSpice, and never tried to use a 4046 in it. I'll bet they have a model for it somewhere, though. I would think you could just play with the propagation delay values in the HC4046 model to make it work with any other logic family. I've built a ton of PLLs with the PLLatinum and Analog Devices chips, but only one with a 4046. -- john, KE5FX _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
