E. Board Layers
The TSDMRX-19V20W-EVM PCB is based on a four layer design as shown below. The ground plane in layer two is
recommended to reduce noise and signal crosstalk. The EVM placed all components on the top of the board for
easier evaluation of the system. End product versions of this design can be made significantly smaller by
distributing components on both sides of the board. The Gerber files for this artwork can be downloaded from the
Semtech web page.
