(1) Definition of VCM changes:

(2) Note that VOD is the differential voltage swing measured across a 100Ω termination resistance connected directly between the transmitter differential pins. |VOD| is the magnitude of the peak to peak voltage swing across the P and N output pins. Because VCM cancels out when measured differentially, VOD voltage swings relative to 0. Rise and fall times are defined for the differential VOD signal as follows:

GUID-18BB8B53-E2A8-4C9D-BEA0-8263D7F89E4F-low.gif

(3) When TX data input = '1', differential output voltage VOD1 is defined. When TX data input = '0', differential output voltage VOD0 is defined. As such, the steady state magnitude of the difference is: |VOD| (Δ) = ||VOD1| – |VOD0||.
