The present invention relates to cross-over conversion in data transfer applications, such as SerDes. Signal routing in such environments is not trivial. Thus, it may not be possible to preserve the physical alignment of the tracks running between devices without recourse to track cross-over. The present invention provides a receiver with selective sign inversion which can compensate for such a cross over, particularly a differential data input; a sign select input; a converter having inputs coupled to said differential data inputs and having first and second outputs, wherein said converter is adapted to convert a differential data signal received at said differential data input into a digital data output at said first output and a sign signal at said second output; and a selective sign inverter having a first input coupled to the sign output of said analogue-to-digital converter, a second input coupled to said sign select input and an output, wherein the signal received at the first input of said selective sign inverter is selectively inverted in dependence on the signal received at said second input in order to provide said modified sign select signal.
