Design Tips
Designing for lesser Crosstalk
Routing two single-ended signals as near as possible causes signal integrity problems - the most obvious one being crosstalk. Cross talk is a coupling effect that happens between two high speed signals.Crosstalk could be caused because of capacitive coupling or because of inductive coupling between the high speed traces. These two types of [...]
Designing with guard traces
A guard trace is just another trace that runs between two signals in order to isolate them and reduce coupling between the two traces. The ends of the guard traces are often grounded and this helps in grounding the field lines from the high speed traces. Some times guard traces are used to isolate just a single critical high speed signal such as a [...]
How to route Differential Traces
While routing differential traces, the following points need to be considered for good EMC and Signal Integrity performance. Any compromise on these points should be avoided and enough care should be taken to make sure the differential routing rules stay as a priority. This is very much required because the differential signals typically carry [...]
Impedance Matching
On a Printed Circuit Board, Impedance matching refers to the technique used by electronics engineers to match the impedance of the source driver with the impedance of the trace, generally with the use of external components. The idea behind impedance matching is to achieve maximum power transfer by minimising energy reflections. Impedance [...]
