High-Speed Serial Interfaces (HSSI)
each have a peak-to-peak swing of A – B volts. This is also referred as each signal wire’s
single-ended swing.
Differential output voltage, VOD (or differential output swing):
The differential output voltage (or swing) of the transmitter, VOD, is defined as the difference of
the two complimentary output voltages: VSD_TX –VSD_TX. The VOD value can be either positive
or negative.
Differential input voltage, VID (or differential input swing):
The differential input voltage (or swing) of the receiver, VID, is defined as the difference of the two
complimentary input voltages: VSD_RX –VSD_RX. The VID value can be either positive or
negative.
Differential peak voltage, VDIFFp
The peak value of the differential transmitter output signal or the differential receiver input signal
is defined as differential peak voltage, VDIFFp = |A – B| volts.
Differential peak-to-peak, VDIFFp-p
Because the differential output signal of the transmitter and the differential input signal of the
receiver each range from A – B to –(A – B) volts, the peak-to-peak value of the differential
transmitter output signal or the differential receiver input signal is defined as differential
peak-to-peak voltage, VDIFFp-p = 2 × VDIFFp = 2 × |(A – B)| volts, which is twice of differential
swing in amplitude, or twice of the differential peak. For example, the output differential
peak-to-peak voltage can also be calculated as VTX-DIFFp-p = 2 × |VOD|.
Common mode voltage, Vcm
The common mode voltage is equal to one half of the sum of the voltages between each conductor
of a balanced interchange circuit and ground. In this example, for SerDes output, Vcm_out =
VSD_TX + VSD_TX = (A + B)/2, which is the arithmetic mean of the two complimentary output
voltages within a differential pair. In a system, the common mode voltage may often differ from
one component’s output to the other’s input. Sometimes, it may be even different between the
receiver input and driver output circuits within the same component. It is also referred to as the DC
offset.
Figure 38. Differential Voltage Definitions for Transmitter or Receiver
To illustrate these definitions using real values, consider the case of a CML (current mode logic)
transmitter that has a common mode voltage of 2.25 V and each of its outputs, TD and TD, has a swing
