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 Si5340-D-EVB can also accommodate an external reference clock instead of a crystal. To evaluate the device with a REFCLK, C93 and C94 must be populated and the XTAL removed (see Figure 3 below). The REFCLK can then be applied to J25 and J26. Figure 3. External Reference Input Circuit 7. Clock Input Circuits (INx/INxB and FB_IN/FB_INB) The Si5340-D-EB has eight SMA connectors (IN0/IN0B – IN2/IN2B and FB_IN/FB_INB) for receiving external clock signals. All input clocks are terminated as shown in Figure 4 below. Input clocks are ac-coupled and 50  terminated. This represents 4 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 Si5340 data sheet. Figure 4.

Clock Output Circuits (OUTx/OUTxB) Each of the eight outputs (four differential pairs) is ac-coupled to its respective SMA connector. The output clock termination circuit is shown in Figure 5 below. The output signal has no dc bias. If dc coupling is required, the ac coupling capacitors can be replaced with a resistor of appropriate value. The Si5340-D-EB provides pads for optional output termination resistors and/or low frequency capacitors. Note: Components with schematic “NI” designation are not normally populated on the Si5340-D-EB and provide locations on the PCB for optional dc/ac terminations by the end user. Figure 5.

Common ClockBuilder Pro Work Flow Scenarios There are three common workflow scenarios when using CBPro and the Si5340-D-EVB. These workflow scenarios are as follows: 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 workflow scenario is described in more detail in the following sections. 10.3.1. 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: 1. Once the PC and EVB are connected, launch ClockBuilder Pro by clicking this icon on your PC's desktop:  Figure 9. ClockBuilder Pro Desktop Icon 2. 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 10. Open Default Plan 3. Once you open the default plan (based on your EVB model number), a popup window appears. Figure 11.

Select Yes to write the default plan to the Si5340 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 12. Writing Design Status 5. After CBPro writes the default plan to the EVB, click on Open EVB GUI as shown in Figure 13. Figure 13. Open EVB GUI 6. The EVB GUI opens. Note: All power supplies are set to the values defined in the device's default CBPro project file created by Skyworks, as shown in Figure 14. Figure 14.

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 (the bottom-right of Figure 14) and then reviewing the voltage, current, and power readings for each VDDx supply. Note: Shutting the VDD and VDDA power supplies "Off" and then "On" 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 15. 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 in 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 in Figure 16. Figure 16.

Workflow Scenario #2: Modifying the Default Skyworks-Created Device Configuration To modify the "default" configuration using the CBPro Wizard, click on Edit Configuration with Wizard. Figure 18. Edit Configuration with Wizard You are then taken to the Wizard's step-by-step menus which allow you to change any of the default plan's operating configurations. Figure 19. Design Wizard Note: You can click on the icon on the lower left hand of the menu to confirm if your frequency plan is valid. After making your desired changes, you can click on Write to EVB to update the DUT to reconfigure your device in real-time. The Design Write status window opens each time you make a change.

Writing a New Frequency Plan or Device Configuration to Non-Volatile Memory (OTP) Note: Writing to the device’s non-volatile memory (OTP) is NOT the same as writing a configuration into the Si5340 using ClockBuilder Pro on the Si5340-D-EB. Writing a configuration into the EVB from ClockBuilder Pro is done using Si5340 RAM space and can be done virtually unlimited number of times. Writing to OTP is limited as described below. Refer to the Si534x/8x Family Reference Manuals and device datasheets 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. Serial Device Communications (Si5340 MCU) 12.1. On-Board SPI Support The MCU on-board the Si5340-D-EB communicates with the Si5340 device through a 4-wire SPI (Serial Peripheral Interface) link. The MCU is the SPI master and the Si5340 device is the SPI slave. The Si5340 device can also support a 2-wire I2C serial interface, although the Si5340-D-EB does NOT support the I2C mode of operation. SPI mode was chosen for the EVB because of the relatively higher speed transfers supported by SPI vs. I2C. 12.2. External I2C Support I2C can be supported if driven from an external I2C controller. The serial interface signals between the MCU and Si5340 pass through shunts loaded on header J17. These jumper shunts must be installed in J17 for normal EVB operation using SPI with CBPro. If testing of I2C operation via external controller is desired, the shunts in J17 can be removed thereby isolating the on-board MCU from the Si5340 device. The shunt at JP1 (I2C_SEL) must also be removed to select I2C as Si5340 interface type. An external I2C controller connected to the Si5340 side of J17 can then communicate to the Si5340 device. (For more information on I2C signal protocol, please refer to the Si5340 data sheet.) Figure 26 below illustrates the J17 header schematic. J17 even numbered pins (2, 4, 6, etc.) connect to the Si5340 device and the odd numbered pins (1, 3, 5, etc.) connect to the MCU. Once the jumper shunts have been removed from J17 and JP1, I2C operation should use J17 pin 4 (DUT_SDA_SDIO) as the I2C SDA and J17 pin 8 (DUT_SCLK) as the I2C SCLK. Please note the external I2C controller will need to supply its own I2C signal pull-up resistors. Figure 26.
