Microstrip versus Stripline

Microstrips are traces on the outer layer of a PCB,
as shown right.








Striplines are traces between two ground planes.
Striplines are less prone to emissions and susceptibility problems since the reference planes effectively shield the embedded traces. However, from the standpoint of high-speed transmission, the two parallel planes creates additional capacitance.

Regarding to LVDS signals, it is recommended the LVDS signals could be routed on microstrip transmission lines if possible.
