Abstract
A receiver with selective sign inversion which can compensate for cross-over conversion is described. Some inputs may be a differential data inputs; a sign select input; a converter having inputs coupled to the differential data inputs and having first and second outputs, wherein the converter is adapted to convert a differential data signal received at the differential data input into a digital data output at the first output and a sign signal at the second output; and a selective sign inverter having a first input coupled to the sign output of the analogue-to-digital converter, a second input coupled to the sign select input and an output, wherein the signal received at the first input of the selective sign inverter is selectively inverted in dependence on the signal received at the second input in order to provide the modified sign select signal.
