**NOTE: The Impedance is set to 48.6 on the external signal traces (Top and Bottom) to
compensate for our manufacturer’s etching process. The end impedance after etching
should result in a 50 ohm Impedance. Always consult with your board manufacturer for
their process/design requirements to ensure the desired impedance is achieved.
