6. Using the Si5348-E-EVB and Installing ClockBuilderPro (CBPro) Desktop Software
6.1 Installing ClockBuilderPro (CBPro) Desktop Software
To install the CBPro software on any Windows 7 (or above) PC:
Go to
http://www.silabs.com/CBPro
and download ClockBuilderPro software.
Installation instructions and User’s Guide for ClockBuilder can be found at the download link shown above. Please follow the instruc-
tions as indicated.
6.2 Connecting the EVB to Your Host PC
Once ClockBuilderPro software is installed, connect to the EVB with a USB cable as shown below.

6.3 Additional Power Supplies
The Si5348-EB comes pre-configured with jumpers installed at JP15 and JP16 (pins 1–2 in both cases) in order to select “USB”. These
jumpers, together with the components installed, configure the evaluation board to obtain all +5 V power solely through the main USB
connector at J37. This setup is the default configuration and should normally be sufficient.
The general guidelines for single USB power supply operation are listed below:
• Use either a USB 3.0 or USB 2.0 port. These ports are specified to supply 900 mA and 500 mA respectively at +5 V.
• If you are working with a USB 2.0 port and you are current limited, turn off enough DUT output voltage regulators to drop the total
DUT current ≤ 470 mA. (Note: USB 2.0 ports may supply > 500 mA. Provided the n5 V drops gracefully by less than 10%,
the EVB will still work.)
• If you are working with a USB 2.0 and you are current limited and need all output clock drivers enabled, re-configure the EVB to
drive the DUT output voltage regulators from an ex5 V power supply as follows:
• Connect ex5 V power supply to terminal block J33 on the back side of the PCB.
• Move the jumper at JP15 from pins 1–2 USB to pins 2–3 EXT.
