For 3V input while maintaining less than 300ps of propagation delay variation.
Driver propagation delays are measured with LVDS differential logic inputs at DHI and DEN.
Output delay is specified with transmission line delay removed.
At less than 0% output amplitude attenuation, DVL = 0V.
Over all recommended operating conditions and junction temperatures.
VDD at 3.3V, VCC = 8.2V, VEE = -5V, junction temperature at 45°C.
