LVDS Driver Output Voltage

The driver’s primary function is to launch an electromagnetic wave into one or two transmission lines. As explained earlier, this is equivalent to generating a voltage across a resistor, albeit a low-valued resistor. Most device specifications designate the differential output voltage as VOD and referenced to the inverting output. Both the minimum and maximum output voltages are significant
