GENERAL DESCRIPTION
The ADF4217L/ADF4218L/ADF4219L are low power dual
frequency synthesizers that can be used to implement local
oscillators in the up-conversion and down-conversion 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
programmable reference divider, programmable A and B counters,
and a dual modulus prescaler (P/P + 1). The A and B 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 fre-
quencies at the PFD input. A complete PLL (phase-locked
loop) can be implemented if the synthesizers are used with an
external loop filter and VCOs (voltage controlled oscillators).
Control of all the on-chip registers is via a simple 3-wire interface
with 1.8 V compatibility. The devices operate with a power supply
ranging from 2.6 V to 3.3 V and can be powered down when
not in use.

NOTES
1Stresses 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 operationalsections
of this specification is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
2This device is a high performance RF integrated circuit with an ESD rating of
< 2 kV and is ESD sensitive. Proper precautions should be taken for handling and
assembly.
3GND = AGND = DGND = 0 V.

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 ADF4217L/
ADF4218L/ADF4219L feature 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.
