Patent ID: 7543090

Claim:
A configurable apparatus for precluding reception errors in an source synchronous receiver, the apparatus comprising: a delay-locked loop, configured to receive a reference clock signal, and configured to generate a select vector signal and an encoded select vector signal, wherein said encoded select vector signal indicates a first time period, and wherein said select vector signal is employed to select one of a plurality of successively delayed versions of said reference clock signal that lags said reference clock signal by a prescribed number of cycles of said reference clock signal, and wherein said first time period is slightly less than said prescribed number of cycles of said reference clock signal; and one or more strobe receivers, each coupled to said delay-locked loop, and said each configured to receive said encoded select vector signal and a corresponding strobe signal, wherein said each is configurable to lock out reception of said corresponding strobe signal for said first time period or for a second time period following transition of said corresponding strobe signal, and wherein said encoded select vector signal is employed to determine said first or second time period by selecting one of a plurality of successively delayed versions of said corresponding strobe signal.
