<p>A voltage-controlled crystal oscillator (VCXO) being controllable by a tuning voltage, the VCXO having a crystal and an adjustable capacitor array. In one example, the VCXO includes an analog to digital converter converting the tuning voltage into corresponding digital values; a memory storing one or more parameters of the crystal and tuning profile; and a logic block receiving the digital values and the one or more parameters of the crystal and tuning profile, said logic block dynamically calculating one or more values for use in adjusting the adjustable capacitor array. In this way, the logic block can dynamically calculate and adjust the operations (i.e., the oscillation frequency) of the VCXO in real time.</p> |
