1. In a communication arrangement having analog circuitry and having digital signal processing circuitry clocked sufficiently fast to generate noise, the analog circuitry susceptible to processing corrupted data due to the noise coupled thereto, a method for reducing noise passed from the digital signal processing circuitry, comprising the steps of:

  • using the analog circuitry to capture information data from an incoming stream for a first time interval while the digital signal processing circuitry is in a reduced-activity mode; and

    in a mode other than the reduced-activity mode occurring during a known guard time for the data being communicated to the communication arrangement and during a second shorter time interval, clocking the digital signal processing circuitry to permit digital signal processing of the captured information data.
