Abstract
Clock sources, apparatuses, and methods for operating crystal oscillators. The method includes determining a first time value indicating an amount of time needed to return a trimming value of the crystal oscillator to a predetermined value. The method also includes determining a second time value indicating an amount of time remaining until a clock signal with a predetermined frequency precision is needed. The method further includes detecting that a difference between the first time value and the second time value is greater than or equal to a predetermined step time. The method also includes incrementing a precision reduction value when the difference between the first time value and the second time value is greater than or equal to the predetermined step time. The method further includes adjusting the trimming value of the crystal oscillator based on a difference between the predetermined value and the precision reduction value.
