Differential signalling is frequently chosen for the distribution of high-speed signals on printed circuit boards (PCBs) since it is commonly superior to conventional single line configurations in terms of electromagnetic interference (EMI) and signal integrity (SI) performance, especially when it is necessary to cross discontinuities placed on the ground plane, such as slits which are often used to isolate noisy or susceptible analog circuits. In the past much work has focused on several effects which slits introduce on classical single line configurations: degradation of the propagation of digital signal with high frequency content [1,2], radiation emission in the neighbourhood of the slits , crosstalk between different lines crossing the same slits . Anyway few works investigate the behaviour of differential signalling: only the excitement of common mode radiation has been studied in .
