Generate a Clock Signal from a Crystal Oscillator
Figure 3-5
Using an Unbuffered Inverter and Schmitt-Trigger Inverter to Generate a Clock Signal From a Crystal Oscillator
Drive crystal oscillators directly.
Can be disabled with added logic.
Allows for selectable system clocks with multiple crystals.
Outputs a clean and reliable square wave.
