FEATURES

Self Contained Evaluation Board including Synthesizer,

VCOs, Loop Filters for generating GSM 1800 standards

(1700MHz to 1800MHz RF, 520MHz to 560MHz IF).

RF and IF filters designed for 20kHz Loop Bandw idth, and

200kHz Channel Spacing.

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

thesizer functions from PC using Window s 95/ 98/ NT.

Battery Operated: Choice of 3V or 5V supplies

On-Board Monitoring of Voltage and Current

Typical RF Phase Noise Perform ance of -84dBc/ Hz @1kHz

offset.

T his board is designed to allow the user to evaluate

the performance of the ADF4212 Frequency Synthe-

sizer for PLL's (Phase Locked Loops). T he block

diagram of the board is shown below. It contains the

footprint for a ADF4212 synthesizer, a pc connector,

SMA connector for the reference input, power sup-

plies and RF output. T here is also a loop filter and a

VCO for both the RF and IF section on board. A

cable is included with the board to connect to a pc

printer port.

T he package also contains Windows 95/98/NT soft-

ware to allow easy programming of the synthesizer.

Typical IF Phase Noise Perform ance of -90dBc/ Hz @1kHz

offset.

Typical Spurious Perform ance of batter than -80dBc

@200kHz offset.

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

supply voltage and current consumption of the ADF4212.

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.

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 ADF4212 V_DDand V_P, and for the VCO

supply. T he default settings are 3V for the ADF4212 V_DD

and 5V for the ADF4212 V_Pand for the VCO supply. It

is ver y im por tant to note that the AD F4212 V_{D D}should

never exceed the AD F4212 V_P. This can dam age the de-

vice.

All components necessary for LO generation are catered

for on-board. T he T CXO connector provides the neces-

sary Reference Input. T he RF PLL is made up of the

ADF4212, passive loop filter and the VCO 190-1750T

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

a standard SMA connector. T he IF PLL is made up of the

ADF4212, passive loop filter 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 connectors to as shown on

the silkscreen and block diagram.

T he software comes on a CD. If the user double clicks on

“AD F4XXXEvaluationSoftware.exe” on the CD , 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\ADF4xxx Evaluation Software”. T o run the

software, simply double-click on “AD F4XXX Eval

Software.exe”.

T he front panel of the evaluation board software is shown

below.

When the device window appears, choose ADF4212 and

click OK. T he main software panel now appears. Click on

Eval Board in the top right hand side of the main software

screen. T he Eval Board Window now appears. Click on
