Let us have a comparison of single ended and differential signalling.
- Driver and Receivers are complex in differential signalling
- Interconnection costs are higher in differential signalling
- Differential signals require strict coupling and routing requirements
- Differential signals can be routed more distance than single ended without much noise affecting the signals
- Single ended signals are more susceptible to noise than differential signals
- Single ended have higher voltage levels and hence better noise margin
- Single ended operates at lower frequencies than differential signal
