EVALUATION BOARD PHOTOGRAPH
GENERAL DESCRIPTION
The EV-ADF4360-8EB1Z board is designed to allow the user to
evaluate the performance of the ADF4360-8 frequency
synthesizer consisting of an integrated PLL and VCO (see Figure 1).
It contains the ADF4360-8BCPZ, 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 user’s PLL requirements. A USB cable is included with the
board 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 numerous other 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 for the evaluation board is shown
in Figure 2. The board schematics are shown in Figure 11,
Figure 12, and Figure 13.
RF OUTPUT STAGE
The RF output stage of the board allows the user to insert a
tuned load for a particular frequency. The particular network
inserted in the board is optimized for 120 MHz operation. For
different frequencies, the output stage needs different component
values. Consult the ADF4360-8 data sheet for further information.
If in doubt, use a 50 Ω resistor instead of the shunt inductor and
a 100 pF bypass capacitor and a 0 Ω resistor instead of the series
in du ctor.
It is important that the same components be placed on the RF
and RF
B lines. In addition, it is essential that both outputs be
OUT
OUT
A
terminated with 50 Ω loads. Otherwise, the output power is not
optimal, and, in some cases, the part may malfunction.
In applications that only use the divider, both RF outputs are
best terminated with a shunt 50 Ω resistor to AV
, a series
DD
100 pF dc bypass capacitor, and a 50 Ω load to GND.
EXTERNAL INDUCTOR OPTIONS
The ADF4360-8 uses external inductors (L1 and L2) to set up the
LC tank circuit of the VCO. The evaluation board has a footprint
for the placement of these. A value of 220 nH is inserted on the
board giving a VCO center frequency of 120 MHz. Insert two
470 Ω resistors (R25 and R26) parallel to ground for both L1 and L2
(see Figure 3).
Figure 2. Evaluation Board Silkscreen—Top View
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. The PLL comprises the ADF4360-8BCPZ and a passive
loop filter. The VCO output from RF
the standard SMA connector, J1, and the complementary RF
A is available through
OUT
OUT
B
VCO output is available from J2.
Users can 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 120 MHz, a PFD frequency of
1 MHz, and a low-pass filter bandwidth of 40 kHz. To design a
filter for different frequency setups, use the ADIsimPLL simulation
software.

To find the optimum frequency range for a given inductor, see
Figure 4. Ensure that the desired frequency is between the two
lines and determine the appropriate inductance needed.

EVALUATION BOARD SOFTWARE QUICK START PROCEDURES
The control software and USB drivers for EV-ADF4360-8EB1Z
accompany the EV-ADF4360-8EB1Z 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 3.5
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, you can install the
.NET framework directly from the CD. Do this by double-clicking
dotnetfx.exe. Once installed, run ADF4360_Setup.msi again.
WINDOWS XP OS
After you have installed the software, install the USB drivers.
To do so, use the following steps:
1. Plug a USB cable into the USB connector on the evaluation
board. The Found New Hardware box opens. See Figure 5.
2. Choose Install from a list or specified location
(Advanced).
If the installation is successful, the message in Figure 6 appears.
Figure 6. Successful Installation
WINDOWS VISTA OS AND WINDOWS 7 (32-BIT) OS
For Windows Vista or Windows 7 (32-bit), you must 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. Click Continue Anyway when asked about Windows Logo
testing.
