SETTING UP THE POWER AND PC CONNECTIONS Set up the power and PC connections as follows: 1. 2. 3. 4. 5. 6. Install the HMC7043 evaluation software before connecting the HMC7043 evaluation board to the PC for the first time (see the Installing the Software section). Administrative privileges are required for the installation. Connect a 5 V supply voltage to the VCCIN-TP14 test point of the HMC7043 evaluation board. Connect the USB interface board to the HMC7043 evaluation board, as shown in Figure 2. Connect the USB cable to the USB interface and the PC. The Found New Hardware Wizard automatically appears when the USB interface connects. Select Install the software automatically and then click Next. The Found New Hardware Wizard may appear twice during the installation. See the Evaluation Board Software section for details on running the HMC7043 evaluation board software. The HMC7043 evaluation board contains an on-board, LDO regulator to regulate the 5 V to 3.3 V supply domain. The HMC7043 evaluation board can bypass the linear regulator, which is useful for measuring the power consumption of the HMC7043. See the evaluation board schematics and printed circuit board (PCB) layout artwork on the HMC7043 evaluation kit page. Bypass the 5 V on-board LDO regulator for the HMC7043 as follows: 1. 2. 3. 4. Apply 0 V to VCCIN (TP14). Apply 3.3 V to 3.3V_MAIN (TP15). Remove R245 and FB20. Populate R12 (to isolate the serial peripheral interface (SPI) board current consumption from the HMC7043). Connect a bench 3.3 V power supply to each of the supply pins on the 3.3 V main headers (TP15 and TP16). It is important that the 5 V supply is not connected to TP15 of the HMC7043 evaluation board. SETTING UP THE SIGNAL CONNECTIONS After setting up the power and PC connections, use the following procedure to set up the signal connections: 2. Connect a signal generator to the CLKIN_P, J8, SMA connector. By default, the reference inputs on the HMC7043 evaluation board are ac-coupled. Terminate the CLKIN_N, J9, SMA connector with a 50 Ω termination. An amplitude setting of 6 dBm from the signal generator is sufficient. Connect an oscilloscope, spectrum analyzer, or other lab equipment to any out of the CLKOUTx_P or CLKOUTx_N SMA connectors. Place a 50 Ω termination on all unused differential output pairs. 13687-002 1. Figure 2.

When a widget value is changed, the new value is written to the register instantly. 13687-005 The main window of the HMC7043 evaluation board software comprises five subsection tabs that correspond to the major functional blocks of the HMC7043 (see Figure 5). These subsections, most of which have their own tab, are outlined in this section. From the main window, the tab for each functional block can be accessed by clicking the appropriate tab. Figure 5. GPIO Tab of the HMC7043 Configuration GUI Rev. 0 | Page 5 of 9 UG-892 EK1HMC7043LP7F User Guide MENU BAR OF MAIN WINDOW View Menu File Menu The Log window, accessed by selecting the Log Window from the View menu, allows the user to follow every read or write actions in the GUI. The File menu allows the user to load a previously saved HMC7043 configuration file or to save a new HMC7043 setup file. A setup file (.py) is a text file that contains the HMC7043 register configuration file. To load a previously saved configuration file, select Load Config from the File menu (see Figure 6). Alternatively, to save a new configuration file, select Save Config from the File menu (see Figure 7). The toolbar also offers shortcuts for Save Config and Load Config. Help Menu Selecting Help from the Help menu opens the About window, which contains information such as the revision number, region information, and contact information. USING THE SOFTWARE TO CONTROL THE FUNCTIONAL BLOCKS OF THE HMC7043 Register W/R The update icon (see Figure 8) issues a GUI update command by reading all registers and setting every widget according to read values. Figure 6. Load Config Shortcut Figure 8. Update Icon Figure 7. Save Config Shortcut To exit the HMC7043 software, select Exit from the File menu. Note that saving the current state helps to continue the setup in the future. However, the user must save the setup before exiting; the software does not automatically check to ensure that the existing setup is saved. GPIO Controls The GPIO tab allows the user to control general-purpose input/output to monitor alarms/status indicators to determine the health of the system. Four GPIO configurations can be controlled from this tab (see Figure 5). Rev. 0 | Page 6 of 9 EK1HMC7043LP7F User Guide OUTPUT CHANNEL CONTROLS The phase offset can be varied by three different methods, as shown in Figure 10. Two of them are based on digital delay. One is slip-based delay, which provides unlimited one full clock input cycle delay. To perform slip, the channel multislip mask must be checked, as shown in Figure 10. Enter the number of clock input cycles, and click on Slip. 13687-005 The output channel divider controls shown in Figure 9 are accessed via the OUTPUTS tab. It is usually sufficient to change only the divide ratio because the HMC7043 evaluation board software and the HMC7043 output duty cycle remains 50%. UG-892 13687-006 Figure 9. Output Clock Driver Tab of the HMC7043 Configuration GUI Figure 10. Example Output Channel—Configurable Blocks Rev. 0 | Page 7 of 9 UG-892 EK1HMC7043LP7F User Guide Even numbered outputs (CLKOUTs) are ac-coupled with 150 Ω to ground for each leg on the HMC7043 evaluation board by default. Odd numbered outputs (SCLKOUTs) are ac-coupled with 100 Ω to VCC internally; no termination resistors are on the HMC7043 evaluation board by default. This termination scheme is ideal for current mode logic (CML) drivers. However, this scheme degrades the complementary metal-oxide semiconductor (CMOS) driver performance. Improved CMOS driver performance is achieved by removing the termination resistors. For low voltage differential signaling (LVDS) drivers, differential 100 Ω resistor must be populated on the HMC7043 evaluation board. 13687-007 Access the output termination selection shown in Figure 11 by clicking any of the drop-down lists under DRIVER in the OUTPUTS tab (see Figure 9). It is important to power down unused outputs on the HMC7043 evaluation board because they can be a major source of unwanted spurs. Figure 11.
