NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
2
This device is a high-performance RF integrated circuit with an ESD rating of
<2 kV and it is ESD sensitive. Proper precautions should be taken for handling and
assembly.

Note that aluminum bond wire should not be used with the ADF4106 die.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although the
ADF4106 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended
to avoid performance degradation or loss of functionality.

PIN CONFIGURATIONS
PIN FUNCTION DESCRIPTIONS
Mnemonic Function
R
SET
Connecting a resistor between this pin and CPGND sets the maximum charge pump output current. The nominal
voltage potential at the R
SET
pin is 0.6 V. The relationship between I
CP
and R
SET
is
I
R
CP MAX
SET
=
25 5.
So, with R
SET
= 5.1 k, I
CPMAX
= 5 mA.
CP Charge Pump Output. When enabled this provides ± I
CP
to the external loop filter, which in turn drives the
external VCO.
CPGND Charge Pump Ground. This is the ground return path for the charge pump.
AGND Analog Ground. This is the ground return path of the prescaler.
RF
IN
B Complementary Input to the RF Prescaler. This point must be decoupled to the ground plane with a small bypass
capacitor, typically 100 pF. See Figure 3.
RF
IN
A Input to the RF Prescaler. This small signal input is ac coupled to the external VCO.
AV
DD
Analog Power Supply. This may range from 2.7 V to 3.3 V. Decoupling capacitors to the analog ground plane
should be placed as close as possible to this pin. AV
DD
must be the same value as DV
DD
.
REF
IN
Reference Input. This is a CMOS input with a nominal threshold of V
DD
/2 and a dc equivalent input resistance of
100 kΩ. See Figure 2. This input can be driven from a TTL or CMOS crystal oscillator or it can be ac coupled.
DGND Digital Ground
CE Chip Enable. A logic low on this pin powers down the device and puts the charge pump output into three-state
mode. Taking the pin high will power up the device depending on the status of the power-down bit F2.
CLK Serial Clock Input. This serial clock is used to clock in the serial data to the registers. The data is latched into the
24-bit shift register on the CLK rising edge. This input is a high impedance CMOS input.
DATA Serial Data Input. The serial data is loaded MSB first with the two LSBs being the control bits. This input is a
high impedance CMOS input.
LE Load Enable, CMOS Input. When LE goes high, the data stored in the shift registers is loaded into one of the four
latches, the latch being selected using the control bits.
MUXOUT This multiplexer output allows either the Lock Detect, the scaled RF or the scaled Reference Frequency to be
accessed externally.
DV
DD
Digital Power Supply. This may range from 2.7 V to 3.3 V. Decoupling capacitors to the digital ground plane
should be placed as close as possible to this pin. DV
DD
must be the same value as AV
DD
.
V
P
Charge Pump Power Supply. This should be greater than or equal to V
DD
. In systems where V
DD
is 3 V, it can be
set to 5 V and used to drive a VCO with a tuning range of up to 5 V.
