Three main types of impedance control Three main types of impedance control 


Single ended impedance control: In this type, only a single trace is used to control the impedance in the PCB, and a reference ground layer is created based on these single ended traces.
 

Differential control impedance: In this type, there are two parallel line widths with a certain spacing to maintain the signal integrity of the PCB. In addition, only a reference layer was created for this section, or a fully grounded layer was designed. This basically depends on the PCB designer.
 

Coplanar control impedance: In this type, the single ended and differential ended traces have some defined planar spacing on the same impedance layer, and the impedance also requires a reference ground layer. It is suitable for both single ended and differential ends.
