The COM pin must be bypassed to ground with an appropriate value capacitor. For details of how to choose the capacitor value, refer to Section 8.1.3. C_COM should be placed as close as possible to the COM pin. The COM signal should be tied to a small copper fill placed underneath the INn signals. The INn signals should stay clear of other high frequency traces.

Each active channel needs to have an LC resonator connected to the corresponding INn pins. The sensor capacitor should be placed within 10 mm of the corresponding INn pin, and the inductor should be placed at the appropriate location next to (but not touching) the metal target. The INn traces should be at least 6 mil (0.15 mm) wide to minimize parasitic inductances.
