3. 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: VSDn_RX – VSDn_RX. The VID value can be either positive or
negative.
4. 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.
5. Differential Peak-to-Peak, VDIFFp-p
Since 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-peak voltage
can also be calculated as VTX-DIFFp-p = 2*|VOD|.
6. Differential Waveform
The differential waveform is constructed by subtracting the inverting signal (SDn_TX, for
example) from the non-inverting signal (SDn_TX, for example) within a differential pair. There is
only one signal trace curve in a differential waveform. The voltage represented in the differential
waveform is not referenced to ground. Refer to Figure 40 as an example for differential waveform.
7. 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 =
VSDn_TX + VSDn_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 as the DC
offset in some occasions.
