* Generated by LTspice 26.0.1 for Windows.
* Setup the Simulator:\n1. Control Panel->Spice->Reset to Default\n2. Control Panel->Hacks->Reset to Default\n3. Control Panel Hacks->Supply a min. inductor damping->click off\n4. Don't use integartion method Gear. It tends to let die the oscillation.\n5. Start your simulations with a lower Q of the crystal to reduce startup simulation time.
