1.1
The IC is a very low power consumption single chip FSK/ASK Superheterodyne
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 integrated VCO, a
PLL synthesiser, a crystal oscillator, a limiter with RSSI generator, a PLL FSK
demodulator, a data filter, an advanced data comparator (slicer) with selection between
two threshold modes and a peak detector. Additionally there is a power down feature to
save current and extend battery life, and two selectable alternatives of generating the
data slicer threshold.
