1.1
The IC is a very low power consumption single chip FSK/ASK Superheterodyne
Receiver (SHR) for the frequency band 300 to 340 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.
