Which of the following ensures that a crystal oscillator operates on the frequency specified by the crystal manufacturer?
Provide the crystal with a specified parallel inductance
Provide the crystal with a specified parallel capacitance✓Bonne réponse
Bias the crystal at a specified voltage
Bias the crystal at a specified current
Explication
A crystal cut for parallel resonance is calibrated by the manufacturer with a stated load capacitance across it. Providing that specified parallel capacitance in the circuit puts the crystal on its marked frequency; a different load pulls the frequency slightly off.
