EVALUATION BOARD PHOTOGRAPH

GENERAL DESCRIPTION

The EV-ADF4360-9EB1Z board is designed to allow the
user to evaluate the performance of the ADF4360-9 frequency
synthesizer consisting of an integrated PLL and VCO (see
Figure 1). It contains the ADF4360-9BCPZ, a USB connector,
and SMA connectors for the RF outputs. Unpopulated SMA
footprints are available for the power supplies, lock detect, 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 mini-USB cable to connect
to the USB port of a PC. The silkscreen for the evaluation board
is shown in Figure 2. It is important that the software be
installed before connecting the board. If the user encounters
any installation warning messages during connection, select

Continue Anyway. If another Install hardware procedure
wizard runs when the software is executed, allow it to install.

The board schematics are shown in Figure 11, Figure 12, and
Figure 13.

Users can provide their own power supplies using the J4 and J5
connectors, as shown in Figure 2.

The on-board filter is a third-order, passive low-pass filter. It
contains three capacitors (C13, C14, and C15) and 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 360 MHz, a PFD frequency of 1600 kHz, and a
low-pass filter bandwidth of 40 kHz. To design a filter for different
frequency setups, use the ADIsimPLL simulation software.

Note that only very high performance measurement equipment
is capable of measuring good jitter performance below 180 MHz.
The Agilent E5052A/E5052B and Rohde & Schwarz FSUP are
both good instruments for this purpose.

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 360 MHz operation. For
different frequencies, the output stage needs different component
values. Consult the ADF4360-9 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 0 Ω resistor instead of the series
in du ctor.

It is very important that the same components be placed on the
RF

A and RF

OUT

outputs be 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
100 pF dc bypass capacitor, and a 50 Ω load to GND.

The board is powered from a single 9 V battery or USB connec­tion. All components necessary for local oscillator (LO) or
DIVOUT generation are available on board. A 19.2 MHz TCXO
from Fox Electronics provides the necessary reference input.
Otherwise, an external reference signal can be connected via J3
(to disable the TCXO, remove R3 and R4). The PLL is composed
of the ADF4360-9 and a passive loop filter. The VCO output

EXTERNAL INDUCTOR OPTIONS

The ADF4360-9 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 22 nH is
inserted on the board giving a VCO center frequency of
360 MHz. Insert two 470 Ω resistors (R25 and R26) parallel to
ground for both L1 and L2 (see Figure 3).

EVALUATION BOARD SOFTWARE QUICK START PROCEDURES

The control software and USB drivers for EV-ADF4360-9EB1Z
accompany the EV-ADF4360-9EB1Z 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, 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).

4. 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).
