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