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 transceiver includes a driver stage and a transient-triggered ring suppression circuit. The driver stage has a first transistor coupled between a supply voltage terminal and a first bus terminal and a second transistor coupled between a ground and a second bus terminal. The transient-triggered ring suppression circuit is coupled to the first and second transistors. The transient-triggered ring suppression circuit is configured to be enabled upon transition of the transceiver from a dominant state to a recessive state. Further, while the transceiver is in the recessive state, the transient-triggered ring suppression circuit is configured to attenuate ringing on at least one of the first or second bus terminals.

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.
