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. | Summary of Features: Low supply current (Is = 5.7/5.9 mA typ. in FSK mode, Is = 5.0/5.2 mA typ. in ASK mode for 434/868 MHz); Supply voltage range 5V 10%; Power down mode with very low supply current (50nA typ.); FSK and ASK demodulation capability; Fully integrated VCO and PLL Synthesiser; ASK sensitivity better than -106 dBm over specified temperature range (- 40 to 105C); FSK sensitivity better than -100 dBm over specified temperature range (- 40 to 105C); Selectable frequency ranges 810-870 MHz and 400-440 MHz; 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 | Target Applications: Keyless Entry Systems; Remote Control Systems; Alarm Systems; Low Bitrate Communication Systems
