ASK/FSK RECEIVER 433/868MHZ Description

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 +105°C)
  • FSK sensitivity better than -100 dBm over specified temperature range (- 40 to +105°C)
  • 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
