Si 5 3 5 6 - EVB Si5356 E VALUATION B OARD U SER ’ S G U I D E Description EVB Features The Si5356 evaluation board (EVB) is used for evaluating the Si5356 I2C programmable, any frequency 1–200 MHz, quad frequency 8-output clock generator. Fully powered from a single USB port On-board 25 MHz XTAL allows standalone asynchronous operation GUI programmable VDD supply allows device to operate from 3.3 V, 2.5 V, or 1.8 V (core) GUI programmable VDDO supplies allows each of the four banks of outputs to have its own supply voltage selectable from 3.3 V, 2.5 V, and 1.8 V GUI controlled voltage, current, and power measurements of VDD and all four VDDO supplies. Voltage supply jumpers allows easy access for use of external supplies or current measurements. Figure 1. Si5356 Evaluation Board Rev. 0.2 6/10 Copyright © 2010 by Silicon Labs Si5356-EVB Si5356-EVB 1. Quick Start 1. Install the Si5356 ClockBuilder™ Desktop Software and driver. (Assumes that Microsoft .NET Framework 1.1 is already installed.) 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 Start Programs Silicon Laboratories ClockBuilder Desktop Software. 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 I2C conversion, controls 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. I2C jumpers allow disconnecting the Si5356 from the I2C bus to allow external control from another I2C master. 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.

EVB Functional Block Diagram 2 Rev. 0.2 +5V Si5356-EVB 2.1. Status LEDS There are three status LEDs on the EVB: RDY (Green) indicates that the EVB is operating as normal. This LED should always be on. BUSY (Green) lights when there is active communication between the PC, the MCU, and the Si5356. INTR (Red) indicates the MCU has detected that the interrupt pin of the Si5356 device is enabled. The most probable cause for an interrupt is because the Si5356 has lost its input signal or the PLL has lost lock. The “Status” tab of the GUI will identify the event that caused the interrupt to happen. 2.2. Inputs The Si5356 EVB provides two reference options - using the on-board XTAL or an external reference. Note: Si5356-EVB Rev 1.0 does not support synchronous operation using the CLKIN input. This feature will be supported in future revisions. 2.2.1. External Input reference An SMA connector (CLKIN) is provided to receive an external single-ended CMOS signal. This input is dc-coupled to the device. The signal should have a minimum amount of dc bias to ensure that it never swings below ground level. 2.2.2. On-board XTAL The on-board 25 MHz allows the Si5356 EVB to generate asynchronous clocks. To use this option, select the XTAL input from the Si5356 “ClockBuilder Desktop” software. 2.3. Outputs (CLK0-CLK7) Each of the eight output clocks can be accessed using SMA connectors. The outputs are dc-coupled (no in-line dc blocking capacitors between the output pin and the SMA connector). 2.4. Control Pins Header J7 located on the backside of the Si5356 EVB allows setting three Si5356 control pins: SSC_DIS, I2C_LSB, and OEB. 2.4.1. SSC_DIS This pin allows disabling of the spread spectrum feature on the output clocks. Spread spectrum is disabled when the jumper is installed. 2.4.2. I2C_LSB This pin is the least significant bit of the Si5356 I2C address allowing up to two Si5356 devices to occupy the same I2C bus. I2C address of the Si5356 = 0x70 when the jumper is installed. I2C address of the Si5356 = 0x71 when the jumper is not installed. 2.4.3. OEB This pin allows disabling all output clocks. All outputs are enabled when the jumper is installed. 2.5. Voltage Regulators The Si5356 EVB has five built-in programmable voltage regulators to allow setting of the VDD supply (to 3.3 V, 2.5 V, and 1.8 V) and the four VDDO supplies (to 3.3 V, 2.5 V, and 1.8 V). The voltage level on each of these supplies can be set independently. 2.6. Reset Switch A reset switch is provided to reset communication between the PC and Si5356 EVB. Rev. 0.2 3 Si5356-EVB 3. ClockBuilder Desktop Software Installation The following sections describe how to install and begin using the software. There is also a readme.txt file with the installation files as well as a user guide installed with the software. 3.1.

USBXpress Driver Installation The EVB uses the Silicon Laboratories' USBXpress driver to allow the EVB to communicate with the computer via USB. The driver is installed after the EVB software is installed. Click Install to run the driver installation. Clicking Cancel will not install any files, and the EVB will not work with the software. Figure 4. Driver Installer Dialog Note: If the driver has already been installed on the computer before, it will not be reinstalled, and a message box will appear as shown in Figure 5. Figure 5. Driver Already Installed The installer will copy the necessary driver files and update the operating system. However, for every different EVB connected to the same computer, the hardware installation wizard will run to associate this driver with the new EVB. Let the wizard run with its default settings. Figure 6 shows a successful driver installation. 6 Rev. 0.2 Si5356-EVB Figure 6. Successful Driver Installation Rev. 0.2 7 Si5356-EVB The USBXpress driver may be removed via the Add and Remove Programs utility in the Control Panel.
