3.10 How to Enable Features and/or Configuration Settings Not Available in ClockBuilder Pro for Factory Pre-programmed
Devices
As with essentially all software utilities, ClockBuilder Pro is continuously updated and enhanced. By registering at www.silabs.com and
opting in for updates to software, you will be notified whenever changes are made and what the impact of those changes are. This
update process will ultimately enable ClockBuilder Pro users to access all features and register setting values documented in this data
sheet and the Si5380 Reference Manual .
However, if you must enable or access a feature or register setting value so that the device starts up with this feature or a register
setting, but the feature or register setting is NOT yet available in CBPro, you must contact a Silicon Labs applications engineer for as-
sistance. Examples of this type of feature or custom setting are the customizable output amplitude and common voltages for the clock
outputs. After careful review of your project file and custom requirements, all Silicon Labs applications engineer will email back your
CBPro project file with your specific features and register settings enabled, using what is referred to as the manual "settings override"
feature of CBPro. "Override" settings to match your request(s) will be listed in your design report file. Examples of setting "overrides" in
a CBPro design report are shown below:

Once you receive the updated design file, simply open it in CBPro. After you create a custom OPN, the device will begin operation after
startup with the values in the NVM file, including the Silicon Labs-supplied override settings.
