WebbObufds is an output buffer that supports low-voltage differential signals. the Obufds isolates the internal circuitry and provides the drive current to the signal on the chip. Its output is represented by an O and OB two separate interfaces. One can be thought of as the main signal and the other can be thought of as from the signal.
