AN19219 - WirelessUSB™ Crystal Guidelines
AN19219 describes how to design a crystal layout and choose the correct crystal for a WirelessUSB™ system. It also describes PCB layout, crystal PPM, load capacitance, and frequency measurements.
A properly designed WirelessUSB™ system can easily operate within a 10 m range. Carefully designed WirelessUSB systems can operate beyond this 10 meter range. Many system design parameters will affect the range of your system. One of the most important of these is a properly designed clock source.
