Question A-003-004-010

Out of the following oscillators, one is NOT, by itself, considered a high-stability reference:

Correct Answer

voltage-controlled crystal oscillator (VCXO)

Explanation

While a VCXO uses a crystal, its frequency can be varied by an external voltage. This variability, though small, means it's less stable as a fixed reference compared to a plain crystal oscillator (XO) or an oven-controlled one (OCXO).
