GENERAL DESCRIPTION
The ADF7011 is a low power OOK/ASK/FSK/GFSK UHF
transmitter designed for use in ISM band systems. It contains
and integrated VCO and Σ-∆ fractional-N PLL. The output
power, channel spacing, and output frequency are program-
mable with four 24-bit registers. The fractional-N PLL enables
the user to select any channel frequency within the European
433 MHz and 868 MHz bands, allowing the use of the ADF7011
in frequency hopping systems. The fractional-N also allows the
transmitter to operate in the less congested sub-bands of the
868 MHz to 870 MHz SRD band.
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.
