General Description

The IC is a very low power consump- Package

tion single chip FSK/ASK Superhet-

erodyne Receiver (SHR) for the

frequency bands 810 to 870 MHz and

400 to 440 MHz. The IC offers a high

level of integration and needs only a

few external components. The device

contains a low noise amplifier (LNA), a

double balanced mixer, a fully inte-

grated VCO, a PLL synthesiser, a

crystal oscillator, a limiter with RSSI

generator, a PLL FSK demodulator, a

data filter, a data comparator (slicer)

and a peak detector. Additionally there

is a power down feature to save bat-

tery life.
