Product Description

The IC is a very low power consumption single chip FSK/ASK Superheterodyne Receiver (SHR) for the frequency band 400 to 440MHz. 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 synthesizer, 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.

Features
  • Low supply current (Is = 5.7mA typ. in FSK mode, Is = 5.0mA typ. in ASK mode)
  • Power down mode with very low supply current (50nA typ.)
  • FSK and ASK demodulation capability
  • Fully integrated VCO and PLL Synthesizer
  • ASK sensitivity better than -106 dBm over specified temperature range (-20 to 70°C)
  • FSK sensitivity better than -100 dBm over specified temperature range (-20 to 70°C)
  • Limiter with RSSI generation, operating at 10.7MHz
  • 2nd order low pass data filter with external capacitors
  • Data slicer with selection between two threshold modes
