Differential Signaling Characteristics
This section describes the DC and AC characteristic of the differential transmitters and receivers. This includes impedance and voltage levels required for compliant operation of the differential transmitters and receivers.
Differential DC Characteristics
Figure 14-2 illustrates a differential link connection between a transmitter and receiver. The specification defines the impedance and subsequent voltages that will be developed under steady-state conditions (i.e., when transmitter is driving a differential 0 or 1).
