General Description
The IC is a low power consumption
single chip FSK/ASK Transceiver for
half duplex low datarate communica-
tion in the 868-870MHz band. The IC
offers a very high level of integration
and needs only a few external compo-
nents. It contains a highly efficient
power amplifier, a low noise amplifier
(LNA) with AGC, a double balanced
mixer, a complex direct conversion
stage, I/Q limiters with RSSI genera-
tion, an FSK demodulator, a fully inte-
grated VCO and PLL synthesizer, a
tuneable crystal oscillator, an onboard
data filter, a data comparator (slicer),
positive and negative peak detectors,
a data rate detection circuit and a 2/3-
wire bus interface. Additionally there is
a power down feature to save battery
power.
