EVALUATION BOARD PHOTOGRAPH

GENERAL DESCRIPTION

The ADF4360-2EBZ1 evaluation board is designed to allow the
user to evaluate the performance of the ADF4360-2 frequency
synthesizer consisting of an integrated PLL and VCO (see Figure 1).
It contains the ADF4360-2BCPZ, 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 USB cable is included
with the board to allow software programmability from a PC.

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 it 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 9 through Figure 11.

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 2000 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 contains a tuned load for the
particular frequency of operation. The particular network inserted
in the board is optimized for 2000 MHz operation. This consists
of a 2 nH shunt inductor, a 10 pF series capacitor, and a 2 nH
series inductor. If in doubt, use a 50 Ω resistor instead of the
shunt inductor, a 100 pF bypass capacitor, and a series 0 Ω
resistor. It is important that the same components be placed
on the RF
that both outputs be terminated with 50 Ω loads. Otherwise,
the output power is not optimum, and in some cases, the part
may malfunction.

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 ADF4360-2BCPZ and
a passive loop filter. The VCO output from RF

EVALUATION BOARD SOFTWARE QUICK START PROCEDURES

The control software and USB drivers for EVAL-ADF4360­2EBZ1 accompany the E VA L -ADF4360-2EBZ1 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 and USB drivers will be installed in
the 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 do 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 3.

2. Choose Install from a list or specified location

(Advanced).

3. Browse to C:\Program Files\Analog Devices\ADF4360.

4. Click Continue Anyway when asked about Windows Logo

testing.

5. If the install was successful, the message box in Figure 4

appears.
