FAQ

1, for only one output of the clock signal line, how to achieve differential wiring?

It is meaningful to use differential wiring for both the signal source and the receiver. Therefore, it is not possible to use differential wiring for clock signals with only one output.

2. Can a matching resistor be added between the receiver differential line pairs?

The matching resistance between the differential pairs at the receiving end is usually added, and its value should be equal to the value of the differential impedance. This signal quality will be better.

3. Why are the differential pair wiring close and parallel?

The wiring of differential pairs should be close and parallel as appropriate. The so-called proper proximity is because this spacing affects the value of the differential impedance, which is an important parameter for designing a differential pair. The need to be parallel is also due to maintaining the consistency of the differential impedance. If the two lines are suddenly missed, the differential impedance will be inconsistent, which will affect the signal integrity and timing delay.
