1. A method of synchronizing data sampled by a first clock to a second clock, comprising:

  • periodically generating a data received flag as a function of said first clock and a data complete flag as a function of said second clock;

    generating a clock error signal as a function of said data received and data complete flags; and

    fractionally resampling the data as a function of the clock error signal, wherein the clock error signal generation comprises counting at least a portion of a period between data receive flags and counting at least a portion of a period between data complete flags, the fractional resampling being a function of ratio of counts.
