Install the Si50x EVB GUI software by downloading it from www.silabs.com/Si501-2-3-4-EVB 2. Launch the Si50x EVB GUI software. The following screen should appear on your desktop: 2 Rev. 0.1 Si501/2/3/4-EVB 3. Insert the Si501-2-3-4-EVB board into an unused USB port. You should now see same screen as before, but with a green "check" next to EVB board graphic. EVB is now recognized by GUI software. Rev. 0.1 3 Si501/2/3/4-EVB 4. Default frequency clock of 100 MHz should now be output from SMA "J1" circled below. 5. To change the output frequency, enter a desired frequency in "New Frequency" field and press "Set Frequency" button. 6. The Si504 can be placed in any supported Run Mode or Power/Jitter mode by pressing the appropriate radio buttons. The GUI will automatically update the device. 7. The Freq Adj and Offset Adj tabs are for utilizing the frequency offset feature of the Si504. Use the Offset Adj tab to enter an offset in terms of PPM. Use the Freq Adj tab to enter an offset in terms of desired frequency. 4 Rev. 0.1 Si501/2/3/4-EVB 1.1.

The MCU provides the following functions: Supports USB communication to host PC single-wire communication (C1) to the DUT on behalf of the host PC per the EVB GUI Software Supplies 3.3 V to peripheral ICs (the serial number generator and the C1 voltage level shifter) Supports 3. Power Supply The Si501/2/3/4-EVB can be powered from USB or from an external voltage supply. This is to support temperature testing without a USB connection. The power supply consists of a Maxim MAX8869 adjustable voltage regulator that steps down the USB +5 V or an external +5V power supply to one of a selectable 1.8, 2.5, or 3.3 V. VDD selection is made via jumper P2. The supply voltage for all the device sites, both Si504 and eval sites, can be adjusted to one of three settings: 3.3 V, 2.5gV, or 1.8 V by jumper P2. (Note that all four locations share the same supply voltage, so any supply voltage change will affect all devices at sites U1, U2, U3, and U4.) The default setting, connecting pins 2 and 3 as shown above, is 3.3 V. Moving the jumper to connect pins 1 and 2 results in 2.5 V. Removing the jumper altogether will result in 1.8 V supply voltage. The voltage regulator may be bypassed by connecting VDD directly to the VDD P1 connection point. 4. LEDs Two green indicator LEDs are driven by the on-board MCU. A "Ready" LED (D1) is illuminated to indicate the EVB is recognized by the EVB GUI software and ready for use. A "USB" LED (D2) is illuminated whenever USB communications are actively in progress. Rev. 0.1 9 Si501/2/3/4-EVB 5. Current Sense Resistor Figure 6. Current Sense Resistor Location Each device site has a 1.0 resistor in series with the VDD supply of that device. Both sides of that resistor are connected to a set of test points. This test point pair can be used to measure the voltage across that supply resistor, which indicates the supply current consumed by the respective device. 6. Outputs Figure 7. SMA Outputs Each device site output is connected to a SMA connector through a series resistor. J1 is the SMA connector output of the on-board Si504, with J2 through J4 corresponding to evaluation sites U2 through U4. 10 Rev. 0.1 Figure 8. Si501/2/3/4 Schematic (1 of 2) Si501/2/3/4-EVB 7.
