ClockBuilder Pro Software (CBPro)
Speeds up Clock Tree Design
ClockBuilder Pro (CBPro) is designed to simplify clock tree design and device configuration. This software uses an easy-to-operate user interface that can customize Silicon Labs’ Clock Generators and Jitter Attenuators, request a custom part number and request custom phase noise plot reports. CBPro connects to all related EVBs and the CBPro Field Programmer that can then be used to program devices already mounted on customer boards. Release notes, Command Line Interface (CLI) documentation and general training information are also included in the software package.
