Operating Conditions  
Figure 5–2 shows the transmitter output waveforms for all supported  
differential output standards (LVDS, mini-LVDS, RSDS, differential 1.5-V  
HSTL class I and II, differential 1.8-V HSTL class I and II, differential  
SSTL-2 class I and II, and differential SSTL-18 class I and II).

Notes to Figure 5–2:  
(1) VOD is the output differential voltage. VOD = |p – n|.  
(2) VOCM is the output common mode voltage. VOCM = (p + n)/2.  
(3) The p – n waveform is a function of the positive channel (p) and the negative channel (n).  
Table 5–9 shows the DC characteristics for user I/O pins with differential  
I/O standards.
