Board Layout Recommendations

Figure 1. Using DRY Package

Figure 2. Using YFP Package

The TPD4S012 can provide system-level ESD protection to the high-speed differential ports. The flow-through

package offers flexibility for board routing. Figure 1 and Figure 2 show the board layout scheme for the D+ and

D– lines of a single differential pair. It allows the differential signal pairs couple together right after they touch the

ESD ports of the TPD4S012.
