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.

Abstract: A driver includes first and second resistors coupled to a supply voltage and coupled to pairs of main transistors at positive and negative output nodes. The first and second pairs of main transistors provide emphasis and de-emphasis on the positive and negative output nodes. The driver also includes a delay inverter, a pull up booster and a pull down booster. The delay inverter delays and inverts each of a pair of differential input signals to provide delayed and inverted differential signals. The pull up booster provides a bypass current path that bypasses the first and second resistors but includes at least some of the first and second pairs of main transistors. The pull down booster provides an additional current path from the supply voltage through the first or second resistor to ground.
