External Reference Input (XA/XB) An external reference (XTAL) is used in combination with the internal oscillator to produce an ultra-low jitter reference clock for the DSPLL and for providing a stable reference for the free-run and holdover modes. The Si5345-D-EVB can also accommodate an external reference clock instead of a crystal. To evaluate the device with a REFCLK, C111 and C113 must be populated and the XTAL removed (see Figure 4 below). The REFCLK can then be supplied to J39 and J40. Figure 4.

Clock Input Circuits (INx/INxB) The Si5345-D-EB has eight SMA connectors (IN0, IN0B–IN3, IN3B) for receiving external clock signals. All input clocks are terminated as shown in Figure 5 below. Note input clocks are ac-coupled and 50  terminated. This represents four differential input clock pairs. Single-ended clocks can be used by appropriately driving one side of the differential pair with a single-ended clock. For details on how to configure inputs as single-ended, please refer to the Si5345 data sheet. Figure 5. Input Clock Termination Circuit 8. Clock Output Circuits (OUTx/OUTxB) Each of the twenty output drivers (10 differential pairs) is ac-coupled to its respective SMA connector. The output clock termination circuit is shown in Figure 6 below. The output signal will have no dc bias. If dc coupling is required, the ac coupling capacitors can be replaced with a resistor of appropriate value. The Si5345-D-EVB provides pads for optional output termination resistors and/or low frequency capacitors. Note that components with schematic “NI” designation are not normally populated on the Si5345-D-EB and provide locations on the PCB for optional dc/ac terminations by the end user. Figure 6.

Installing ClockBuilder Pro Desktop Software To install the CBOPro software on any Windows 7 (or above) PC: Go to www.skyworksinc.com/en/application-pages/clockbuilder-pro-software and download ClockBuilder Pro software. Installation instructions and User’s Guide for ClockBuilder Pro can be found at the download link shown above. Please follow the instructions as indicated. 10. Using the Si5345-D-EVB 10.1. Connecting the EVB to Your Host PC Once ClockBuilder Pro software is installed, connect to the EVB with a USB cable as shown below. Figure 7.

Additional Power Supplies Although additional power (besides the power supplied by the host PC’s USB port) is not needed for most configurations, two additional +5 VDC power supplies (MAIN and AUX) can be connected to J33 and J34 (located on the bottom of the board, near the USB connector). Refer to the Si5345-D-EB schematic for details. The Si5345-D-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. Figure 8 shows the correct installation of the jumper shunts at JP15 and JP16 for default or standard operation. Figure 8. JP15-JP16 Standard Jumper Shunt Installation Errata Note:Some early versions of the 64-pin Si534x-EVBs may have the silkscreen text at JP15-JP16 reversed regarding EXT and USB, i.e., USB EXT instead of EXT USB. Regardless, the correct installation of the jumper shunts for default or standard operation is on the right hand side as read and viewed in Figure 8. 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 nominal +5 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, reconfigure the EVB to drive the DUT output voltage regulators from an external +5 V power supply as follows: Connect Move 8 external +5 V power supply to terminal block J33 on the back side of the PCB. the jumper at JP15 from pins 1-2 USB to pins 2-3 EXT.

Overview of ClockBuilder ProApplications Note: The following instructions and screen captures may vary slightly depending on your version of ClockBuilder Pro. The ClockBuilder Pro installer will install two main applications: Figure 9.

Common ClockBuilder Pro Work Flow Scenarios There are three common workflow scenarios when using CBPro and the Si5345-D-EVB. These workflow scenarios are: Workflow Scenario #1: Testing a Skyworks-Created Default Configuration Workflow Scenario #2: Modifying the Default Skyworks-Created Device Configuration Workflow Scenario #3: Testing a User-Created Device Configuration Each is described in more detail in the following sections. 10.5. Workflow Scenario #1: Testing a Skyworks-Created Default Configuration The flow for using the EVB GUI to initialize and control a device on the EVB is as follows. Once the PC and EVB are connected, launch ClockBuilder Pro by clicking on this icon on your PC’s desktop. Figure 11. ClockBuilder Pro Desktop Icon If an EVB is detected, click on the “Open Default Plan” button on the Wizard’s main menu. CBPro automatically detects the EVB and device type. Figure 12. Open Default Plan Once you open the default plan (based on your EVB model number), a popup will appear. Figure 13.

This ensures the device is completely reconfigured per the Skyworks default plan for the DUT type mounted on the EVB. Figure 14. Writing Design Status After CBPro writes the default plan to the EVB, click on “Open EVB GUI” as shown below. Figure 15. Open EVB GUI The EVB GUI will appear.

Verify Free-Run Mode Operation Assuming no external clocks have been connected to the INPUT CLOCK differential SMA connectors (labeled “INx/INxB”) located around the perimeter of the EVB, the DUT should now be operating in free-run mode, as the DUT will be locked to the crystal in this case. You can run a quick check to determine if the device is powered up and generating output clocks (and consuming power) by clicking on the Read All button highlighted above and then reviewing the voltage, current and power readings for each VDDx supply. Note: Shutting “Off” then “On” of the VDD and VDDA supplies will power-down and reset the DUT. Every time you do this, to reload the Skyworks-created default plan into the DUT’s register space, you must go back to the Wizard’s main menu and select “Write Design to EVB”: Figure 17. Write Design to EVB Failure to do the step above will cause the device to read in a pre-programmed plan from its non-volatile memory (NVM). However, the plan loaded from the NVM may not be the latest plan recommended by Skyworks for evaluation. At this point, you should verify the presence and frequencies of the output clocks (running to free-run mode from the crystal) using appropriate external instrumentation connected to the output clock SMA connectors. To verify the output clocks are toggling at the correct frequency and signal format, click on View Design Report as highlighted below. Figure 18.

Writing a New Frequency Plan or Device Configuration to Non-Volatile Memory (OTP) Note: Writing to the device non-volatile memory (OTP) is NOT the same as writing a configuration into the Si5345 using ClockBuilder Pro on the Si5345-D-EB. Writing a configuration into the EVB from ClockBuilder Pro is done using Si5345 RAM space and can be done virtually unlimited numbers of times. Writing to OTP is limited as described below. Refer to the Si534x/8x Family Reference Manuals and device data sheets for information on how to write a configuration to the EVB DUT’s non-volatile memory (OTP). The OTP can be programmed a maximum of two times only. Care must be taken to ensure the configuration desired is valid when choosing to write to OTP. 12.
