Impedance Simulation of Differential Transmission Lines Considering ESD Protection Diode Components

Transmitting high-bandwidth data between transmitter and receiver over a single twisted pair (STP) requires additional ESD (electrostatic discharge) protection components at transmitter and receiver sides. These protection components are mounted on the printed circuit board (PCB). With a data rate of 6 Gbps, the design of the PCB transmission line has to consider the ESD protection components in terms of signal integrity. In this blog article, we present the influence of the ESD protection component and the necessary layout optimization to preserve the signal integrity. Finally, we show the comparison between the simulation result and measurement.
