... Rev 1.0 November 2006 Pin Configuration Below is a top view diagram of the EN5335QI package. NOTE: NC pins are not to be electrically connected to each other or to any external signal, ground, or voltage. However, they must be soldered to the PCB. Failure to follow this guideline may result in part malfunction or damage. ...

... Only the large thermal pad and the perimeter pads are to be mechanically or electrically connected to the PC board. The PCB top layer under the EN5335QI should be clear of any metal except for the large thermal pad. The “grayed-out” area in Figure 4 represents the area that should be clear of any metal (traces, vias, or planes), on the top layer of the PCB. © ...
