Hello people.

Does someone here have any SPICE model for 4046 PLL IC?
Some I've found use PSpice' digital syntax.

Why dont you just make one.?

Hint: Look at the block diagram in the app note. Copy the circuit and
press the "create subckt model" button in a Spice that has such a
feature.

I have version 10.0 (the latest). It has a SYMBOL for the 4046 but no
MODEL :-(

Chaos,

LTspice has an intrinsic type-2 digital phase detector.
It's output is a current that is plus or minus Iout
depending which input has had the most recent extra
edge, otherwise zero output current. Usually it's only
used inside its multiphase SMPS models that have
PLL's, but you can see how to use it in the file
../examples/Educational/PLL2.asc. However, it's not
a model, but an intrinsic LTspice device, so it won't
run in other SPICE's.

This is something. Thanks.
