PCB Layout Recommendations
The TX/RX filter components should be small form factor capacitors and resistors. They should be placed as close
as possible to the XPIO 110 device.
The TX filter components should be surrounded by a copper trace to GND. As shown below, the RX filter compo-
nents should be enclosed by the GND.
