1. A method of operation within clock-data recovery (CDR) circuitry, the method comprising:

  • detecting an out-of-alignment condition between a first sampling clock signal and a data signal;

    slewing the phase of the first sampling clock signal at a first slew rate in response to detecting the out-of-alignment condition; and

    slewing the phase of the first sampling clock signal at a second, slower slew rate after exiting the out-of-alignment condition.
