The ADF4210/ADF4211/ADF4212/ADF4213 is a dual frequency
synthesizer that can be used to implement local oscillators (LO)
in the upconversion and downconversion sections of wireless
receivers and transmitters. They can provide the LO for both
the RF and IF sections. They consist of a low-noise digital PFD
(Phase Frequency Detector), a precision charge pump, a pro-
grammable reference divider, programmable A and B Counters
and a dual-modulus prescaler (P/P + 1). The A (6-bit) and B
(12-bit) counters, in conjunction with the dual modulus prescaler
(P/P + 1), implement an N divider (N = BP + A). In addition,
the 14-bit reference counter (R Counter), allows selectable
REFIN frequencies at the PFD input. A complete PLL (Phase-
Locked Loop) can be implemented if the synthesizer is used with
an external loop filter and VCO (Voltage Controlled Oscillators).

The synthesizer phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO and subtracting 20 logN (where N is the N divider value). See
TPC 16.

The phase noise is measured with the EVAL-ADF4210/ADF4212/ADF4213EB Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the

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.

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.

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 ADF4210/ADF4211/ADF4212/ADF4213 features proprietary ESD protection circuitry, per-
manent 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.

Function
Power Supply for the RF Section. Decoupling capacitors to the ground plane should be placed as
close as possible to this pin. V
DD
1 should have a value of between 2.7 V and 5.5 V. V
DD
1 must have
the same potential as V
DD
2.
Power Supply for the RF Charge Pump. This should be greater than or equal to V
DD
1. In systems where
V
DD
1 is 3 V, it can be set to 6 V and used to drive a VCO with a tuning range up to 6 V.
Output from the RF Charge Pump. This is normally connected to a loop filter which drives the input
to an external VCO.
Ground Pin for the RF Digital Circuitry.
Input to the RF Prescaler. This low level input signal is ac-coupled from the RF VCO.
Ground Pin for the RF Analog Circuitry.
RF/IF Fastlock Mode.
Reference Input. This is a CMOS input with a nominal threshold of V
DD
/2 and an equivalent input
resistance of 100 kΩ. This input can be driven from a TTL or CMOS crystal oscillator.
Digital Ground for the IF Digital, Interface and Control Circuitry.
This multiplexer output allows either the IF/RF Lock Detect, the scaled RF, scaled IF or the scaled
Reference Frequency to be accessed externally.
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.
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.
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.
Connecting a resistor between this pin and ground sets the maximum RF and IF charge pump output
current. The nominal voltage potential at the R

pin is 0.66 V. The relationship between I

Output from the IF Charge Pump. This is normally connected to a loop filter which drives the input
