MULTIPLE SIGNAL FORMAT OUTPUT BUFFER |
摘要 |
<p>An output buffer circuit (100) 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 (104) and at least one differential circuit (102) coupled to a pair of outputs (108, 110). One of the single-ended buffer and the differential circuit is selectively enabled to provide a signal to the outputs.</p> |
