GENERAL DESCRIPTION
This board is designed to allow the user to evaluate the performance of the ADF4002 frequency synthesizer for phase-locked
loops (PLLs). Figure 1 shows the board, which contains the
footprint for an ADF4002 synthesizer, an SMA connector for
the reference input, power supplies, and an RF output. There is
also a footprint for a loop filter and a VCO on board.
The evaluation kit also contains software that is compatible with
Windows® XP and later versions to allow easy programming of
the synthesizer.
This board requires an SDP-S (system demonstration platformserial) board (shown in Figure 1, but not supplied with the kit).
The SDP-S allows software programming of the ADF4002 device.

QUICK START GUIDE
Follow these steps to quickly evaluate the ADF4002 device:
1. Solder the VCO (T-package compatible).
2. Solder the loop filter components (design with ADIsimPLL™).
3. Connect the reference frequency to J11.
4. Install the system development platform (SDP) drivers.
5. Install the Int-N software.
6. Connect the SDP-S motherboard to the PC and to the EV-ADF4002SD1Z.
7. Follow the hardware driver installation procedure.
8. Connect the power supplies to banana connectors (6 V to 12 V).
9. Run the Int-N software.
10. Select the SDP board and the ADF4002 device in the Select Device and Connection tab of the software front panel window.
11. Click the Main Controls tab. Update all registers.
12. Connect the spectrum analyzer to J2.
13. Measure the results.

EVALUATION BOARD HARDWARE
The evaluation board requires the use of an SDP-S motherboard
to program the device. This is not included and must be
purchased separately. The EV-ADF4002SD1Z schematics are
shown in Figure 21, Figure 22, and Figure 23.
POWER SUPPLIES
The board is powered from external banana connectors. The
voltage can vary between 6 V and 12 V. The power supply
circuit provides 3.0 V to the ADF4002 V
to choose either 3.0 V or 5 V for the ADF4002 V
settings are 3.0 V for the ADF4002 V
V
. Note that VDD should never exceed 3.3 V. This can damage
P
the device.
External power supplies can be used to directly drive the device.
In this case, the user must insert SMA connectors as shown in
Figure 2.
INPUT SIGNALS
The necessary reference input can be sourced from an external
generator. A low noise, high slew rate reference source is best
for achieving the stated performance of the ADF4002. This
reference source can be connected to Connector J11. If
preferred, the edge mount connector, J5, can be inserted and
used instead. A third option is to solder a footprint-compatible
TCXO to Footprint Y2. To use this option, connect 0 Ω links to
R16 and R14.
Digital SPI signals are supplied through the SDP connector, J1.
Using the SDP-S platform is recommended. The SDP_B can
also be used, but Resistor R57 must be removed on the SDP-B
board. Some additional spurious low frequencies may appear if
the SDP-B connector is used.

OUTPUT SIGNALS
All components necessary for LO generation can be inserted on
board. The PLL is made up of the ADF4002 synthesizer, a
passive loop filter, and the VCO. The package containing the
VCO must be a T-package (or similar). A low-pass filter must
be inserted between the charge pump output and the VCO
input. In this case, the user must insert the relevant parts as
shown in Figure 2. The VCO output is available at RFOUT
through a standard SMA connector, J2. The MUXOUT signal
can be monitored at Test Point T8 or at SMA Connector J3.

SYSTEM DEMONSTRATION PLATFORM (SDP)
The system demonstration platform (SDP) is a series of controller boards, interposer boards, and daughter boards that can be
used for easy low cost evaluation of Analog Devices, Inc.,
components and reference circuits. It is a reusable platform
whereby a single controller board can be reused in various
daughter board evaluation systems.
Controller boards connect to the PC via USB 2.0 and provide a
range of communication interfaces on a 120-pin connector.
The pinout for this connector is strictly defined. This 120-pin
connector’s receptacle is on all SDP daughter boards, component evaluation boards, and Circuits from the Lab™ reference
circuit boards. There are two controller boards in the platform:
the SDP-B, which is based on the Blackfin® ADSP-BF527, and
the SDP-S, which is a serial interface only controller board.
The SDP-S has a subset of the SDP-B functionality.
Interposer boards route signals between the SDP 120-pin connector and a second connector. When the second connector is
also a 120-pin connector, the interposer can be used for signal
monitoring of the 120-pin connector signals. Alternatively, the
second connector allows SDP platform elements to be integrated
into a second platform, for example, the BeMicro SDK. More
information on the SDP can be found at www.analog.com/sdp.

EVALUATION BOARD SETUP PROCEDURE
SOFTWARE INSTALLATION
Use the following steps to install the SDP drivers and Int-N
software.
1. Install the SDP drivers by double-clicking SDPDrivers.exe
and following the relevant installation instructions. See the
UG-291 for further instructions on installation of the SDP-S
platform or the UG-277 if the SDP-B platform is used.
2. Install the Analog Devices Int-N software by double-
clicking ADI_Int-N_Setup.msi.
If you are using Windows XP, follow the instructions in the
Windows XP Software Installation Guide section (see
Figure 3 to Figure 7).
If you are using Windows Vista or Windows 7, follow the
instructions in the Windows Vista and Windows 7 Software
Installation Guide section (see Figure 8 to Figure 12).
Note that the software requires Microsoft Windows
Installer and Microsoft .NET Framework 3.5 (or higher).
The installer connects to the Internet and downloads
Microsoft .NET Framework automatically. Alternatively,
before running the ADI_Int-N_Setup.msi, both the
installer and .NET Framework can be installed from the
CD provided.
3. Connect your SDP board (black) or USB adapter board
(green) by USB. If you are using an SDP board, the drivers
install automatically, and you are ready to run the software.
If you are using a USB adapter board on Windows XP,
follow the steps in the Windows XP Driver Installation
Guide section (see Figure 13 to Figure 16).
On Windows Vista or Windows 7, the drivers install
automatically.
