A parallel receiver interface includes a plurality of parallel data receivers, each receiver receiving input data. A clock receiver is configured to receive a forwarded clock. A phase interpolator has an input coupled to the output of the clock receiver and has an output coupled to each of the parallel receivers. Parallel clock delay elements are within each of the parallel data receivers, each clock delay element configured to provide varying amounts of clock phase adjustment. Inputs of a multiplexer circuit within each of the parallel data receivers are coupled to the outputs of each of the parallel clock delay elements within a respective parallel data receiver. An output of the multiplexer circuit is coupled to a data sampler within the respective parallel data receiver, the multiplexer circuit being configured to be controlled by a logic signal.
