2 Vpp is referenced multiple times in the document as the input range, but with the bias voltage of .95 that would potentially put the input voltage over the stated absolute maximum of 1.9V. In the theory of operation section it's also mentioned how each differential line can only swing .5 away from the bias voltage, which would give a max voltage swing of 1 Vpp, not the 2 that is mentioned. Which of these is correct?
