In fi niBand
A number of high-speed serial data communication standards have been introduced to address the need for next generation
I/O connectivity. One of these interface standards, In
fi niBand, is brie fl y discussed here. (See Figure 14.)
An In fi niBand communication lane includes two independent differential signaling paths, one for transmit and one for receive,
both operating at a 2.5 Gb/s rate. As shown in the example below, the differential output parameter is speci fi ed as a
peak-to-peak voltage difference, and thus the signal swing on each pin of the driver is half that value.
The V
diff
signal shown in (b) is measured with a differential probe connected between the two signals in (a). The V
diff
signal represents the result of the receiver processing the two complementary input signals from the driver shown in (a),
and cannot be measured directly as a single-ended signal.
