Abstract
A method can be used for compensating a voltage drop on a cable connected between a source device and a receiver device. The source device delivers an offset current on a channel configuration pin of the source device, the offset current causing an increase in a voltage on the channel configuration pin of the source device to a chosen reference voltage. The offset current is stored in the source device. The source device absorbs an absorption current originating from the channel configuration pin of the source device, the absorption current depending on the stored offset current and on the voltage drop. The source device generates a compensated supply voltage on a power supply pin of the source device, the compensated supply voltage equal to a reference supply voltage increased by the voltage drop to within a tolerance.
