Differential Signaling vs. Single-Ended Circuit
Featured Product from Aker Technology USA Corporation
Relative to a signal line and a ground line in a traditional Single-ended signal transmission, Differential Signals take a different approach.
The advantages are:
- Strong anti-interference ability. Phase noise is generally applied to both signal lines at the same time with a difference of 0. The phase noise has no effect on the logical meaning of the signal.
- Effectively suppresses electromagnetic interference (EMI). Since the two wires are close together and the signal amplitudes are equal, the amplitude of the coupled electromagnetic field between the two wires and the ground wire is also equal. The signal polarities are opposite and the electromagnetic fields will cancel each other out. Therefore, electromagnetic interference to the external environment is also minimized.
- Timing positioning is accurate. The receiving end of the differential signal is the point where the difference between the signal amplitudes on the two lines changes positively and negatively. This is used as the point where the logic 0/1 transition is judged. Ordinary single-ended signals use the threshold voltage as the transition point of the signal logic 0/1, which is greatly affected by the ratio of the threshold voltage to the signal amplitude voltage and is not suitable for low-amplitude signals.
