differential signal

differential signal

[‚dif·ə′ren·chəl ′sig·nəl]
(electronics)
In a circuit, a signal that is the voltage difference between two nodes, neither of which is at ground potential. Also known as floating signal.

3V signal looks massive next to a differential signal operating in the hundreds of millivolts, so even a small amount of crosstalk from such a signal can cause big problems for the differential pair.
Agilent's new InfiniiMax III+ probes offer InfiniiMode technology, which greatly expands the measurement capabilities and usability of the probe, making it capable of measuring all the components of a differential signal.
When paired with the Tektronix DPO/DSA73304D oscilloscope, the P7600 Series Probing System provides connectivity and signal fidelity for high speed differential signal measurements on serial bus designs like PCI Express.
When the signal in the two channels is a 0 to 1 V signal in one and a 1 V to 0 signal in the other, everyone calls this a differential signal.
Common-Mode signaling requires the transmitter to drive both the + and - signal to the same 250mV level, thus squelching the differential signal.
FUNDAMENTALLY, A DIFFERENTIAL signal route path enables two complementary signals (N and P) to be sent from a driver to a receiver.
The upper left quadrant describes how a differential signal goes into one port and a differential signal comes out a port.
This new problem can completely swamp the differential signal at the receiver and can make the difference between a robust product and one that works with boards from some vendors but not others.

Quite frankly, the number of systems using single-ended cabling is negligible due to the benefits of differential signal transmission such as reduced EMI and longer transmission distances.
The only hindrance to its extensive use is the fact that every differential signal requires two wires, a set of drivers and a set of receivers.
This is the impedance seen by the differential signal and is based on the individual impedance of the two traces and the coupling between the traces.
