16. PCB Layout Considerations
PCB layout considerations to be taken when using the SX8722 are relatively simple to get the highest performances out.
The most important to achieve good performances is to have a good voltage reference.
Separating the digital from the analog lines will be also a good choice to reduce the noise induced by the digital lines. It is
also advised to have separated ground planes for digital and analog signals with the shortest return path, as well as making
the power supply lines as wider as possible and to have good decoupling capacitors.
17. How to Evaluate
For evaluation purposes the XE8000EV120 evaluation kit can be ordered. This kit connects to any PC using a USB port. The
"SX8722 Evaluation Tools" software gives the user the ability to control the SX8722 and displaying configurations on the
"Graphical User interface". For more information please look at SEMTECH web site (http://www.semtech.com).
