Abstract
A low voltage differential signal (LVDS) input circuit with extended common mode range has been disclosed. One embodiment of the LVDS input circuit includes a first resistor coupled between a differential logic circuit and a first input pad, a second resistor coupled between the differential logic circuit and a second input pad, and a first and a second termination resistors coupled to the first and the second input pads, respectively, the first and second termination resistors being coupled to each other in series at a node to produce a common mode reference voltage at the node. Other embodiments are described and claimed.
