Abstract
A register-based de-skew system and method for a source synchronous receiver circuit domain. In one embodiment, a de-skew strobe generator operates responsive to at least one incoming strobe signal in order to generate a plurality of one-hot de-skew strobe signals. A plurality of de-skew registers receive the same input data pulses from a transmitter circuit domain. By clocking the de-skew registers with the one-hot de-skew strobe signals, the input data pulses are stretched into spread data pulses having an extended timing window. A plurality of multiplexers multiplex the spread data pulses, whereupon the multiplexed data is registered using a clock signal associated with the receiver circuit domain.
