Typical parameters are measured at VDD = 3.3V, TA = 25°C. They are for reference purposes, and are not production-tested.
(2)
Differential output voltage VOD is defined as ABS(OUT+–OUT). Differential input voltage VID is defined as ABS(IN+–IN).
(3)
Output offset voltage VOS is defined as the average of the LVDS single-ended output voltages at logic high and logic low states.
