Si5356-EVB
1. Quick Start
1. Install the Si5356 ClockBuilder™ Desktop Software and driver. (Assumes that Microsoft .NET Framework 1.1 is
2. Connect a USB cable from the EVB to the PC where the software was installed.
3. Leave the jumpers as installed from the factory and launch the Si5356 configuration software by clicking on
4. Click on the “ClockBuilder Desktop” to configure the Si5356 using the graphical user interface.
2. Functional Description
A function block diagram of the EVB is shown in Figure 2. The MCU performs the USB to I
the voltage regulators, monitors the INTR pin, and controls the three status LEDs. There are five programmable
voltage regulators (VDD, VDDOA, VDDOB, VDDOC, VDDOD), which supply power to the Si5356 device. VDD and
VDDO jumpers allow the option of powering the device from external supplies or as a convenient point for
measuring current. I
another I
The Si5356 EVB is shipped with an on-board 25 MHz XTAL to allow stand-alone asynchronous operation. The
Si5356 can be synchronized to an external reference using the CLKIN input and selecting the external reference
using the ClockBuilder Desktop software.
