Clock Software Development Tools

 

IMPORTANT: Not all Silicon Labs clocks are customizable under one software.

Clocks with I²C programming as well as our new clock families need desktop software. Pin-controlled clocks can be customized on the web.

Please see the table below to select the appropriate software for your clock generator. Different versions of the ClockBuilder software to configure different products can be installed simultaneously on one computer.

 

Go to Oscillator Software Development Tools for all Silicon Labs oscillators.
