Rotational frequency detector system |
摘要 |
A rotational frequency detector system including a rotational frequency detector responsive to a data signal and a clock signal. The rotational frequency detector is configured to compare the frequency of the clock signal to the frequency of the data signal to define frequency up and frequency down signals that adjust the frequency of the clock signal to be equal to the frequency of the data signal. A step control system is responsive to the rotational frequency detector and a step clock signal and is configured to define predetermined pulse widths for the frequency up and frequency down signals.
