Page "Low-voltage differential signaling" Paragraph 5

The low common-mode voltage ( the average of the voltages on the two wires ) of about 1. 2V allows using LVDS with a wide range of integrated circuits with power supply voltages down to 2. 5V or lower.

In addition, there are variations of LVDS that use a lower common mode voltage.

One example is sub-LVDS ( introduced by Nokia in 2004 ) that uses 0. 9V typical common mode voltage.

Another is Scalable Low Voltage Signaling for 400 mV ( SLVS-400 ) specified in JEDEC JESD8-13 October 2001 where the power supply can be as low as 800 mV and common mode voltage is about 400 mV.
