GENERAL DESCRIPTION

This board is designed to let the user evaluate the performance

of the ADF41020 frequency synthesizer for phase-locked

loops (PLLs). Figure 1 shows the board, which contains the

ADF41020 synthesizer, a 100 MHz TCXO, power supplies, a

USB interface, and an RF output. There is also an active loop

filter and a 13 GHz VCO on board. The evaluation kit contains

software that is compatible with Windows® XP and later

versions to allow easy programming of the synthesizer.

The USB interface allows software programming of the ADF41020

device. A USB cable is included with the board to allow software

programmability.

UG-405 Evaluation Board User Guide EVALUATION BOARD HARDWARE The evaluation board comes with a USB cable to connect to the USB port of a PC. The evaluation board silkscreen is shown in Figure 3. The EV-ADF41020EB1Z schematics are shown in Figure 8, Figure 9, Figure 10, and Figure 11. POWER SUPPLIES The board is powered via two external supplies, 5.5 V and 15 V, and connected as described in the Quick Start Guide Section. INPUT SIGNALS The 100 MHz TCXO provides the necessary reference signal.

Evaluation Board User Guide UG-405 EVALUATION BOARD SOFTWARE Confirm that Analog Devices RFG.L Eval Board connected is displayed at the bottom left of the window (see Figure 4). Otherwise, the software has no connection to the evaluation board. To run the software, click the Int-N v7 file on the desktop or in the Start menu. Note that, when connecting the board, it takes about 5 to 10 seconds for the status label to change.
PAGE 6
UG-405 Evaluation Board User Guide The Main Controls tab controls the PLL settings (see Figure 5). 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 at 100 MHz. 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 MHz).

Evaluation Board User Guide UG-405 EVALUATION AND TEST To evaluate and test the performance of the ADF41020, use the following steps: 3. 4. 5. 6. Install the Analog Devices Int-N software. 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.
