EVALUATION BOARD PHOTOGRAPH
GENERAL DESCRIPTION
The EV-ADF4360-7EB1Z evaluation board is designed to allow
the user to evaluate the performance of the ADF4360-7 frequency
synthesizer consisting of an integrated PLL and VCO (see Figure 1).
It contains the ADF4360-7BCPZ, a USB connector, and SMA
connectors for the RF outputs. Unpopulated SMA footprints are
available for the power supplies, the chip enable (CE), and the
external reference input. The evaluation board also contains
the loop filter to complete the PLL. It can be modified as necessary
for the PLL requirements of the user. A cable is included with
the board to connect a PC parallel port to allow software programmability.
The package also contains a CD with Windows® software to allow
quick, user-friendly programming of the synthesizer. The CD
contains additional PLL data sheets, technical notes, articles, and
ADIsimPLL™ V3.4 (Analog Devices, Inc., PLL simulation
software). More information is available at www.analog.com/pll.

EVALUATION BOARD HARDWARE
The evaluation board comes with a cable to connect to the
USB port of a PC. The silkscreen and cable diagram for the
evaluation board are shown in Figure 2. The board schematics
are shown in Figure 11 through Figure 13.
Users may provide their own power supplies using the J4 and J5
connectors, as shown in Figure 2. Hardware power-down using
the CE pin can be controlled by inserting an SMA connector
into J6 and removing R12.
The on-board filter is a third-order, passive, low-pass filter.
The filter contains three capacitors (C13, C14, and C15) plus
two resistors (R10 and R11). The footprint for R10 is located on
the underside of the board. The design parameters for the loop
filter are for a center frequency of 900 MHz, a PFD frequency
of 200 kHz, and a low-pass filter bandwidth of 10 kHz. To design a
filter for different frequency setups, use the ADIsimPLL simulation
software.
RF OUTPUT STAGES
The output stage of the board allows users to insert a tuned load
for a particular frequency. The particular network inserted in
the board is optimized for 900 MHz operation. For different
frequencies, the output stage needs different component values.
Refer to the ADF4360-7 data sheet for further information. If in
doubt, use a 50 Ω resistor instead of the shunt inductor, a 100 pF
bypass capacitor, and a 0 Ω resistor instead of the series inductor.
It is important that the same components be placed on the

The board is powered from a single 9 V battery, or from the
USB supply, by changing the position of Switch SW1. All components necessary for LO generation are catered for on-board. A
10 MHz TCXO from Fox Electronics provides the necessary
reference input. Otherwise, an external reference signal can
be connected via J3. (Remove power and signal from the TCXO
by removing Resistors R4 and R5). The PLL comprises the
ADF4360-7BCPZ and a passive loop filter. The VCO output

EXTERNAL INDUCTOR OPTIONS
The ADF4360-7uses external inductors (L1 and L2) to set up
the LC tank circuit of the VCO. The evaluation board has a
footprint for placing these inductors. A value of 3.9 nH is inserted
on the board giving a VCO center frequency of 900 MHz. For
this inductor value and for other inductor values of greater than
3.3 nH, a 470 Ω resistor in parallel to ground for both L1 and L2
must be inserted, as shown in Figure 3.
To find the optimum frequency range for a given inductor, see
Figure 4. Ensure that the desired frequency is between the two
lines and read off the appropriate inductance needed.

EVALUATION BOARD SOFTWARE QUICK START PROCEDURES
The control software and USB drivers for EV-ADF4360-7EB1Z
accompany the EV-ADF4360-7EB1Z on a CD. To install the
software, use the following steps:
1. Open ADF4360_setup.msi.
2. The install wizard guides you through the installation
process. The software is installed in a default directory called
C:/Program Files/Analog Devices/ADF4360.
The software requires Microsoft’s .NET Framework Version 2.0
or later to be installed on your machine. The installer automatically downloads the framework from the Microsoft website if
you do not have this installed. If you do not have an Internet
connection or have a slow connection on the PC, then you
can install the .NET framework directly from the CD. Do
this by double-clicking dotnetfx.exe. Once installed, run
the ADF4360_Setup.msi again.
WINDOWS XP OS
Once you have installed the software, install the USB drivers.
To d o so, use the following steps:
1. Plug in a USB cable to the USB connector on the
evaluation board. The Found New Hardware box
appears. See Figure 5.
2. Choose Install from a list or specified location
(Advanced).
3. Click Continue Anyway when asked about Windows Logo
testing.
4. If the install was successful, the message box in Figure 6
appears.

WINDOWS VISTA OS AND WINDOWS 7 (32-BIT) OS
For Windows Vista or Windows 7 (32-bit), you need to
manually install the drivers. To do so, use the following steps:
1. Find the new unknown device (the evaluation board)
in Device Manager and double-click it to open the
properties. The device should be Unknown device,
under Other devices (see Figure 7).
3. On the Update Driver Software dialog box, choose
Browse my computer for driver software.
4. Browse to C:\Program Files\Analog Devices\ADF4360.
5. Click OK or Next.
6. If prompted by Windows Security, choose Install this
driver software any w a y.
7. If the install was successful, the message box in Figure 9
appears.
Figure 7. Device Manager
2. Click Update Driver in the properties window (see
Figure 8).
Figure 9. Successful Install
WINDOWS 7 64-BIT OS
If you are using Windows 7 64-bit OS, it is recommended to
download Windows XP Mode (a Windows XP emulator) from
Microsoft to run the evaluation board software.
Windows XP Mode allows the device driver package to digitally
sign allowing you to use Windows 7 64-bit OS in native mode.

USING THE EVALUATION BOARD SOFTWARE
The control software for the EV-ADF4360-7EB1Z accompanies
the EV-ADF4360-7EB1Z on a CD. To install the software, see
the Evaluation Board Software Quick Start Procedures section.
To run the software, click the ADF4360.exe file on the desktop
or in the Start menu.
The main interface window appears (see Figure 10). Confirm
that Analog Devices RFG.L Eval Board connected is displayed
at the top of the window. Otherwise, the software has no connection to the evaluation board.
The evaluation board can be connected and disconnected while
the software is running. Note that when connecting the board,
it takes about 5 seconds for the status label to change.
Under the File menu, the current settings can be saved to, and
loaded from, a text file.
Use the REF IN Frequency text box to set correct reference
frequency and the reference frequency divider. The reference
TCXO on the evaluation board runs at 10 MHz.
The Settings section controls the charge pump current setting,
the output power setting, and the multiplexer output setting.
Use the Frequency Settings section to control the output
frequ e nc y. The user can input the desired output frequency
in the RF Output Frequency text box (in megahertz).
In the Registers tab, the user can manually input the desired
value to be written to the registers.
In the Sweeps and hop tab, the user can make the device sweep
a range of frequencies, or hop between two set frequencies.
In the Latches to write section, at the bottom of the window,
the values to be written to each register are displayed. If the
background on the text box is green, then the value displayed
is different to the value actually on the device. Click Wri t e x counter Latch to write that value to the device.
The F2, F3, and F4 keys switch between the three tabs. F12
increases the output frequency by one channel spacing and
writes it to the device. F11 decreases the output frequency by
one channel spacing.
