Frequency Synthesizer

a

EVAL-ADF4213EB1

GE NE RAL D E SC RIP T IO N

FEATURES

Self-Contained Board including Synthesizer, VCO,s and

Loop Filter

Channel Spacing: 200kHz

T his board is designed to allow the user to evaluate the

performance of the ADF4213 Frequency Synthesizer for

PLL's (Phase Locked Loops). T he block diagram of the

board is shown below. It contains the ADF4213 synthe-

sizer, a pc connector, T CXO reference input, power

supplies and IF/RF outputs. Both output channels have a

20kHz loop filter. T he IF channel has a 540MHz VCO

while the RF channel has a 900MHz VCO. A cable is

included with the board to connect to a pc printer port.

RF Output: 900MHz

IF Output:

540MHz

Designed for 20kHz loop bandw idth on both IF and RF

Accom panying Softw are allow s com plete control of synthe-

sizer functions from PC

Battery Operated: Choice of 3V or 5V supplies

Typical Phase Noise Perform ance of -91dBc/ Hz @ 1kHz

offset for RF (900MHz)

T he package also contains windows software to allow

easy programming of the synthesizer.

Typical Spurious Perform ance of better than -90dBc at

200kHz offset from carrier

Figure 2. PC Cable Diagram

T he AD7706 A/D converter is used to monitor the power

supply voltage and current consumption of the ADF4213.

T his helps the user pick the optimum synthesizer settings for

power consumption and also provides an alert if the battery

voltage is too low to sustain the required 3V or 5V for the

board supply.

RF loop component values shown in the circuit diagram are

for 900MHz RF output, 5mA CP current, VCO190-902T ,

200kHz channel spacing and 20kHz loop bandwidth.

IF loop component values are for 540MHz IF output, 5mA

CP current, VCO190-540T , 200kHz channel spacing and

20kHz loop bandwidth.

Figure 1. Evaluation Board Silkscreen

T he board is powered from a single 9V battery. T he power

supply ciruitry allows the user to choose either 3V or 5V for

the ADF4213 V_DDand V_P, and for the VCO supplies. T he

default settings are 3V for the ADF4213 V_DDand 5V for the

ADF4213 V_Pand for the VCO supplies. It is ver y im por tant

to note that the AD F4213 V_{D D}should never exceed the

AD F4213 V_P. This can dam age the device.

All components necessary for LO generation are on-board.

T he 13MHz T CXO from Vectron provides the necessary

Reference Input. T here are two channels controlled by the

AD F4213.

T he RF PLL is made up of one half of the ADF4213, a pas-

sive loop filter (20kHz bandwidth) and the VCO 190-902T

from Vari-L. T he output is available at RFOUT through a

standard SMA connector.

T he IF PLL is made up of one half of the ADF4213, a pas-

sive loop filter (20kHz bandwidth) and the VCO 190-540T

from Vari-L. T he output is available at IFOUT through a

standard SMA connector.

If the user wishes, they may use their own power supplies and

reference input. In this case, they need to insert SMA con-

nectors as shown on the silkscreen and block diagram.

Softwar e D escr iption

If the user wishes to change any of the settings then place the

cursor over the desired parameter (RF VCO Output Fre-

quency, for example) and click once. T his brings up a screen

where it is possible to either type in a new value of output

frequency or else increment and decrement by the channel

spacing.

T he software also allows monitoring of the device supply

voltage, supply current and the charge pump voltage. Simply

hit the "Update Voltage and Current Display" button to get

an up-to-date reading.

T he evaluation board software is contained on a CD-ROM

which comes in the package. T o load the software the user

should click on “setup.exe” , then the install wizard installs

the software. Follow the on-screen directions. T he software

will be installed in a default directory called “C:/Program

Files/Analog Devices”. T o run the software, simply go to the

Start Menu and choose Program/ADF4XXX/

ADF4XXX_rev2. T his will open the software for the evalua-

tion board. T he user will be asked to choose which device is

being evaluated. Click on the ADF4213 button. Hit OK. T he

window shown below will now appear.

In this panel, click on the "Eval Board" button. Choose

ADF4213EB1 from the list on offer. Hit OK. T he synthesizer

will now be programmed with the correct settings for a GSM

system working at 900MHz RF and 540MHz IF. 200kHz

PFD frequency is set up, 32/33 prescaler is chosen and charge

pump current of 5mA is programmed.
