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 1 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.
