GENERAL DESCRIPTION
This ADF4360-2EB1 Evaluation board is designed to
allow the user to evaluate the performance of the
ADF4360-2 Frequency Synthesizers for PLL's (Phase
Locked Loops). The block diagram of the board is
shown below. It contains the ADF4360-2, a PC
connector, plus SMA connectors for the power
supplies, Reference Input, and RF outputs. It also
contains a loop filter to complete the PLL. The eval
board can be setup as necessary for the customer's
PLL requirements. A cable is included with the board
to connect to a PC printer port to allow software
programmability.
The package also contains windows software to allow
easy programming of the synthesizer.

Hardware Description
The evaluation board comes with a cable for connecting to
the printer port of a PC. The silk screen and cable diagram for
the evaluation board are shown below. The board
schematic is shown on pages 3 and 4.
If the the version of version of ADIsimPLL that you are
using is not configured for the ADF4360-2, then you can
design the loop filter by selecting the ADF4106 as a
synthesizer and inserting all other relevant parameters
from the ADF4360-2 datasheet. Be careful to note that the
charge pump current is half that of the ADF4106.

The board is powered from a single 9V battery.
All components necessary for LO generation are catered
for on-board. A 10MHz TCXO from Fox provides the
necessary Reference Input. Otherwise an External
Reference signal can be connected via SMA1.
The PLL comprises the ADF4360-2 and a passive loop
filter. The VCO outputs are available at RFOUTA through
a standard SMA connector, plus the complementary VCO
output is available from RFOUTB complementary
connector.
If the user wishes they may use their own power supplies
and reference input, they can use the SMA connectors as
shown on the silkscreen and block diagram. Control of the
Chip Enable pin can be achieved by inserting J7, and
removing R12. The on board filter is a Third Order,
Passive Low Pass Filter. This contains three capacitors,
(C13, C14 & C15), plus two resistors (R10 & R11). To
save Board space, The footprint for R10 is located on the
underside of the board. For design of the loop filter, It is
designed for a centre frequency of 2.0GHz, and a channel
spacing of 200kHz. The charge pump current setting is
chosen to be 2.5mA. It's bandwidth is 10kHz.
To design a filter for different setups, Please use
ADIsimPLL.

RF OUTPUT STAGES
The output RF stages can be customised to suit the
requirements of the end-user. A tuned load, consisting of a
51nH shunt Inductor for each output (L5 & L6) is
connected to to Vvco. A series 1.5pF coupling capacitor
(C17 & C19) is included plus a series 3.6nH Inductor (L3
& L4) before the RF output to the SMA connector. This
can be changed to optimise tuning to the desired
fundamental frequency.
If in doubt, a 50Ohm resistor can replace the shunt
Inductor, and a zero-ohm link can short out L3 & L4.
ADI SimPLL
A copy of ADIsimPLL is also included on the eval kit
CD. This software package designs, simulates and
analyses the entire frequency domain and time domain
response. You can use it to design an appropriate filter for
the PLL. Various passive and active filter architectures are
allowed.

Software Description
The software comes on a CD. If the user double clicks on
“setup.exe”, then the install wizard installs the software.
Follow the on-screen directions. The software will be
installed in a default directory called “C:/Program Files/
Analog Devices/ADF4360”. To run the software, simply
double-click on “ADF4360.exe”. It should be noted that
this is a beta-version of software for the ADF4360.
Before the main software screen appears, the Device window appears, which will ask the user to choose which device is being evaluated. Choose the appropriate version of
the ADF4360 and click OK. The Main Interface window
will now appear. (See Figure 5).
Programmable Software Settings
Click on RF VCO Output Frequency, and the Output
Frequency window will appear. Enter the desired output
frequency (in MHz) and also the desired PFD frequency
(in kHz) and click OK.Click on Reference Frequency and
Insert the desired frequency in MHz, Again click OK.
Click On Prescaler, and the Prescaler window will appear.
Grab the pointer, and choose the appropriate setting
(Again Click OK).
Click on Charge Pump Current Setting 2 or Charge
Pump Current Setting 1 and the Current Setting window
will appear. Grab the pointer to set the Charge Pump
Current Setting to the appropriate setting based on the
loop design.
It will be necessary to adjust the core power current to
15mA and and the output power current to give optimum
operation. These settings are clearly marked in the
window shown below.
Click on the RF PD Polarity button to set the RF PD
Polarity bit positive.
The part should now be now set up, and other features can
now be examined by the user. To examine the contents
written to each register, the Registers button can be
selected below. As stated on the part's datasheet, The
Correct sequence of Register writes is to the R Counter,
The Function Latch and finally the N Counter Latch.
