SI5342-D-EVB

Si 5342- D- EVB S I 5 3 42 - D E VALUATION B O A R D U S E R ’ S G U I D E Description EVB Features The Si5342-D-EVB is used for evaluating the Si5342 Any-Frequency, Any-Output, Jitter-Attenuating Clock Multiplier revision D. The device revision is distinguished by a white 1 inch x 0.187 inch label with the text “SI5342-D-EB” installed in the lower left hand corner of the board. (For ordering purposes only, the terms “EB” and “EVB” refer to the board and the kit respectively. For the purpose of this document, the terms are synonymous in context.)        Powered from USB port or external power supply. Onboard 48 MHz XTAL or Reference SMA Inputs allow holdover mode of operation on the Si5342. ClockBuilder® Pro (CBPro) GUI programmable VDD supply allows device to operate from 3.3, 2.5, or 1.8 V.

Clock Input Circuits (INx/INxB) The Si5342-D-EB has eight SMA connectors (IN0/IN0B–IN3/IN3B) for receiving external clock signals. All input clocks are terminated as shown in Figure 4 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 Si5342 data sheet. Typically a 0.1 F dc block is sufficient, however, 10 F may be needed for lower input frequencies. Note that the EVB is populated with both dc block capacitor values. Figure 4.

Clock Output Circuits (OUTx/OUTxB) Each of the four output drivers (two differential pairs) is ac-coupled to its respective SMA connector. The output clock termination circuit is shown in Figure 5 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 Si5342-D-EB provides an L-network at OUT0/OUT0B output pins for optional output termination resistors. Note that components with schematic “NI” designation are not normally populated. Figure 5.

External Reference Clock Input Circuit (XA/XB) The Si5342-D-EB supports either XTAL or external reference clock on XA/XB. By default, the XTAL is populated. If a reference clock is required for testing, remove Y1 and place C93/C94. A low-jitter reference clock can then be applied to J25/J26. Note that XA/XB is the jitter reference for the device. Jitter performance at the output of the Si5342 will depend on the jitter performance of the reference clock at XA/XB. Figure 6.

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 8. Application #1: ClockBuilder Pro Wizard Use the CBPro Wizard to: Create a new design Review or edit an existing design Export: create in-system programming Figure 9. Application #2: EVB GUI Use the EVB GUI to: Download configuration to EVB’s DUT (Si5342) Control the EVB’s regulators Monitor voltage, current, power on the EVB 10 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 1.0 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • December 14, 2021 Si5342-D-EVB 10.4. Common ClockBuilder Pro Work Flow Scenarios There are three common workflow scenarios when using CBPro and the Si5342-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 10. 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 11. Open Default Plan Once you open the default plan (based on your EVB model number), a popup will appear. Figure 12. Write Design to EVB Dialog Select “Yes” to write the default plan to the Si5342 device mounted on your EVB. This ensures the device is completely reconfigured per the Skyworks default plan for the DUT type mounted on the EVB. Figure 13.

Figure 14. Open EVB GUI The EVB GUI will appear. Note all power supplies will be set to the values defined in the device’s default CBPro project file created by Skyworks, as shown below. Figure 15. EVB GUI Window 10.5.1. 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 16. 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. 12 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 1.0 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • December 14, 2021 Si5342-D-EVB 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 17. View Design Report Your configuration’s design report will appear in a new window, as shown below. Compare the observed output clocks to the frequencies and formats noted in your default project’s Design Report. Figure 18. Design Report Window 10.5.2. Verify Locked Mode Operation Assuming you connect the correct input clocks to the EVB (as noted in the Design Report shown above), the DUT on your EVB will be running in “locked” mode.

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 Si5342 using ClockBuilder Pro on the Si5342-D-EB. Writing a configuration into the EVB from ClockBuilder Pro is done using Si5342 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.
