A disk drive controller includes a servo system operable to associate a time stamp with an arrival of a servo wedge, a firmware loop and core PLLs in the read channel. The firmware loop is operable to determine a period between the arrival of a pair of consecutive servo wedges and produce a desired frequency of when to read/write data to disk based on the period between the arrival of a pair of consecutive servo wedges. Processing circuitry is operable to adjust a clock signal, wherein the clock signal itself is not locked to the data and produce a fine control signal for the core PLLs in the read channel. These core PLLs are operable to determine a phase and/or frequency associated with when an analog signal is sampled and/or written to disk, wherein these core PLLs comprises Fractional N Sigma Delta PLLs.

摘要:
The present invention relates to frequency dividers. The frequency divider comprises an input, a counter, a first comparator, an interconnect, and an output. The counter has a counter reset port and is configured to receive a clock signal from the input and to produce a sum signal. The first comparator is configured to receive the sum signal, to compare the sum signal to a first integer, and to produce a first comparison signal. The interconnect is configured to convey the first comparison signal from the first comparator to the counter reset port. The output coupled to the first comparator. The clock signal has a periodic waveform. The sum signal represents a first sum, which equals a number of waveforms of the clock signal received by the counter after the counter has been reset. In a first embodiment, the first integer is selectable from a set of at least three consecutive integers. In a second embodiment, a frequency of the clock signal is at least 1.5 gigahertz. A third embodiment includes the features of both the first embodiment and the second embodiment.
