Figure 1 shows the board, which contains the ADF4108 synthesizer, an SMA connector for the reference input, the power supplies, a USB interface, and the RF outputs. There is also an active loop filter and a VCO on board. The user has the option of using an alternate loop filter and VCO by connecting the board to the following SMA connectors: VTUNE and CPOUT. The evaluation kit contains software that is compatible with Windows® XP and more recent versions to allow easy programming of the synthesizer. The USB interface allows software programming of the ADF4108 device. A USB cable is included in the evaluation board kit to allow software programmability. 09145-001 EVALUATION BOARD Figure 1.

Install the Int-N software (see the UG-476 user guide, PLL Software Installation Guide). Follow the hardware driver installation procedure. Connect the power supplies to the EV-ADF4108EB1Z: a. Connect the 5.5 V power supply to the on-board banana connectors. b. Connect the 15 V power supply to the test points labeled +15 V and AGND1. Connect the USB cable to the PC and to the EV-ADF4108EB1Z. Run the Int-N software. Select the ADF4108 device and the USB board in the Select Device and Connection tab of the main window. 8. 9. 10. 11. 12. 13. Rev. B | Page 3 of 16 Ensure that Analog Devices RFG.L Eval Board connected is displayed at the bottom left of the main window. Connect the reference frequency to REFIN (SMA). Click the Main Controls tab to input the RF and other settings. Note that the Phase Detector Polarity drop-down box in the Settings section should be set to Negative to suit the active loop filter in inverting mode. Update all registers. Connect the output to a signal source analyzer. The board offers two outputs. a. VCO/2 via the SMA labeled VCO/2. b. VCO via the SMA labeled EXT_VCOOUT. Measure the results. UG-160 Evaluation Board User Guide EVALUATION BOARD HARDWARE The evaluation board comes with a mini-USB cable to connect the evaluation board to the USB port of a PC. The evaluation board silkscreen is shown in Figure 2. The EV-ADF4108EB1Z schematics are shown in Figure 7 to Figure 10. at the VCO/2 SMA connector. To use an alternate loop filter and VCO, the charge pump output (CPOUT) and the VCO tune voltage (VTUNE) are available as outputs via standard SMA connectors. POWER SUPPLIES DEFAULT OPERATION The board is powered via two external supplies, 5.5 V and 15 V, and connected as described in the Quick Start Guide section. All components necessary for local oscillation (LO) generation can be inserted on the board. The board is shipped with the ADF4108 synthesizer, an active loop filter, and the VCO. INPUT SIGNALS The necessary reference input can be supplied from an external generator. A low noise, high slew rate reference source is best for achieving the stated performance of the ADF4108. This reference source is connected to the REFIN SMA connector. A second option is to solder a footprint-compatible TCXO to Footprint Y1. OUTPUT SIGNALS An active loop filter using standard feedback is inserted between the charge pump output and the VCO input. The design parameters for the loop filter are for a center frequency of 6400 MHz, a PFD frequency of 2500 kHz, and an active loop filter bandwidth of 15 kHz. To design a filter for different frequency setups, use the ADIsimPLL simulation software to generate filter component values and evaluate results. 09145-002 The VCO output is available at EXT_VCOOUT through a standard SMA connector. A divide-by-2 option is also available Figure 2. Evaluation Board Silkscreen Rev. B | Page 4 of 16 Evaluation Board User Guide UG-160 EVALUATION BOARD SOFTWARE Confirm that Analog Devices RFG.L Eval Board connected is displayed at the bottom left of the window (see Figure 3). If this message is not displayed, the software cannot connect to the evaluation board. To run the software, click the Int-N v7 file on the desktop or select the file from the Start menu. Note that when the board is connected, there is about a 5 sec to 10 sec delay before the status label changes. On the Select Device and Connection tab, choose the device and connection method, and then click Connect. From the File menu, the current settings can be saved as and loaded from a text file. 09145-017 The control software for the EV-ADF4108EB1Z is provided on the CD included in the evaluation board kit. To install the software, see the UG-476 user guide, PLL Software Installation Guide. Figure 3. Int-N Software, Main Window—Select Device and Connection Rev. B | Page 5 of 16 UG-160 Evaluation Board User Guide The Main Controls tab controls the PLL settings (see Figure 4). Use the RF Settings section to control the output frequency. You can type the desired output frequency in the RF VCO Output Frequency text box (in megahertz). In the Registers tab, you can manually input the desired value to be written to the registers. In the Sweep and Hop tab, you can make the device sweep a range of frequencies or hop between two set frequencies. Use the Reference Frequency text box to set the correct reference frequency and the reference frequency divider. The default reference on the software window is 100 MHz. 09145-018 The Settings section lets you select general options available for the PLL, including the charge pump current settings and phase detector polarity. The EV-ADF4108EB1Z uses a charge pump setting of 5 mA and a negative phase detector polarity. In the Latches/Registers section at the bottom of the Main Controls tab of the main window, the values to be written to each register are displayed. If the background on the text box is green, the value displayed is different from the value actually on the device. Click Write R Counter Latch or Write N Counter Latch to write the value displayed to the device. To update all Latches in the correct order, click Write All Latches. Figure 4.

To evaluate and test the performance of the ADF4108, use the following procedure: 2. 3. 4. 5. 6. 7. 8. Install the Analog Devices Int-N software (see the UG-476 user guide, PLL Software Installation Guide). Use ADIsimPLL to generate the loop filter component values if a different loop filter is required. Solder new filter components specified by ADIsimPLL. Install the USB software drivers. Connect the evaluation board to a PC using the supplied USB cable. Follow the hardware driver installation procedure that appears. Connect the USB connector to the EV-ADF4108EB1Z. Connect a reference signal to REFIN. Connect a spectrum analyzer to EXT_VCOOUT or VCO/2. Run the Int-N software.
