Clock line terminations are important to ensure the best clocking performance. Failing to create a good termination can cause signal integrity problems such as ringing of the signal, non-monotonic edges, or too slow rise and fall times. Many termination schemes exist. Each kind of interface requires its own specific termination. Single-ended signals can be used to drive differential inputs. However, it is advisable to drive differential inputs with differential clocks, as they are much less sensitive to noise than single-ended clocks. Low-jitter clocks are always differential.
