Abstract
A driver block for a differential pin driver that supports out-of-band signaling. The driver block includes a main enable switch that is controlled by a high speed driver inhibit (DINH) signal. The main enable switch controls coupling between a main current source and a differential pin driver output stage. The main enable switch is coupled in series with an output select switch that selects between a positive output and a negative output. The driver block also includes a positive enable switch for controlling coupling between the positive output and a positive level shifter that shifts voltages of the positive output. The driver block also includes a negative enable switch for controlling coupling between the negative output and a negative level shifter that shifts voltages of the negative output.
