摘要:
Methods and apparatus to lock a phase lock loop to a spindle motor are disclosed. An example controller comprises a counter to determine a period of an operating signal received from a motor, an oscillator to generate a control signal based on an input signal, and an initializer to generate the input value based on the period, wherein the input value causes the oscillator to generate the control signal having the same phase as the operating signal.
