Patent attributes
An output buffer circuit drives multiple signal formats. The output buffer circuit reduces duplication of output bond pads on an integrated circuit die. The output buffer circuit reduces a need for including conversion buffers on system boards. A single integrated circuit including the output buffer circuit may meet a variety of applications. The output buffer achieves these results with a programmable output voltage swing and a programmable output common mode voltage. In some embodiments of the present invention, an integrated circuit includes at least one single-ended buffer and at least one differential circuit coupled to a pair of outputs. One of the single-ended buffer and the differential circuit is selectively enabled to provide a signal to the outputs.
