GENERAL DESCRIPTION
The ADF7010 is a low power OOK/ASK/FSK/GFSK UHF
transmitter designed for use in ISM band systems. It contains
an integrated VCO and sigma-delta fractional-N PLL. The
output power, channel spacing, and output frequency are pro-
grammable with four 24-bit registers. The fractional-N PLL
enables the user to select any channel frequency within the U.S.
902 MHz–928 MHz band, allowing the use of the ADF7010 in
frequency hopping systems.
It is possible to choose from the four different modulation
schemes: Binary or Gaussian Frequency Shift Keying (FSK/
GFSK), Amplitude Shift Keying (ASK), or On/Off Keying
(OOK). The device also features a crystal compensation register
that can provide Ϯ1 ppm resolution in the output frequency.
Indirect temperature compensation of the crystal can be accom-
plished inexpensively using this register.
Control of the four on-chip registers is via a simple 3-wire inter-
face. The devices operate with a power supply ranging from
2.3 V to 3.6 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 operational sections
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
<1 kV and it is ESD sensitive. Proper precautions should be taken for handling and
assembly.
3GND = CPGND = RFGND = DGND = AGND = 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
ADF7010 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.
