Abstract: Systems and methods are disclosed for an integrated circuit (IC) comprising an oscillator, an on-off-keying modulator configured to modulate input data coupled to the oscillator, a serial communications transmitter coupled to the on-off-keying modulator, a serial communications receiver coupled to the serial communications transmitter by a set of cables, and an envelope detector coupled to the serial communications receiver. In the IC, power and data are simultaneously delivered across the same set of cables from the serial communications transmitter to the serial communications receiver.

Abstract: A semiconductor package includes a transformer having a primary winding and a secondary winding. The primary winding has first and second terminals and a pair of taps. The secondary winding has first and second terminals and a pair of taps. The semiconductor package includes first and second data transfer circuits, a bridge, and a rectifier. The first data transfer circuit is coupled to the pair of taps of the primary winding. The second data transfer circuit is coupled to the pair of taps of the secondary winding. The bridge is coupled to the first and second terminals of the primary winding. The rectifier is coupled to the first and second terminals of the secondary winding.
