Abstract
A method of calibrating a data signal receiver configured to receive a multi-bit data signal and an associated data strobe signal, wherein transitions of the data strobe signal indicate sample points for the multi-bit data signal. The method comprises the steps of: receiving, on each bit of the multi-bit data signal, a sample of a predetermined data pattern; determining, for each bit of the multi-bit data signal, a relative start timing value indicative of a start of the predetermined data pattern; determining, for each bit of the multi-bit data signal, a relative end timing value indicative of an end of the predetermined data pattern; determining, for each bit of the multi-bit data signal, a mid-point timing value halfway between the relative start timing value and the relative end timing value; applying a bit timing delay to each bit of the multi-bit data signal such that the mid-point timing values are aligned; and applying a strobe timing delay to the associated data strobe signal to align the associated data strobe signal with the aligned mid-point timing values.
