Pierce-gate oscillator crystal load calculation
The Pierce-gate oscillator is well recognized by most designers, but few understand how to specify the crystal correctly. The crystal used can be either a fundamental AT-CUT or BT-CUT. A BT-CUT crystal has poor frequency stability over temperature compared to an AT-CUT. This topology uses a parallel crystal and not a series crystal....
