ASK/FSK SINGLE CONV. RECEIVER 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 that is pin compatible with the Receiver TDA5210. 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, a data comparator (slicer) and a peak detector. Additionally there is a power down feature to save battery life.

Summary of Features

  • Low supply current (typ. at 868MHz I s = 5.9mA in FSK mode, I s = 5.2mA in ASK mode)
  • 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 < –107dBm
  • Selectable frequency ranges 810-870 MHz and 400-440 MHz
  • Limiter with RSSI generation,operating at 10.7MHz
  • Selectable reference frequency
  • 2nd order low pass data filter with external capacitors
  • Data slicer with self-adjusting threshold
  • FSK sensitivity <-100dBm

Target Applications

  • Keyless Entry Systems
  • Remote Control Systems
  • Alarm Systems
  • Low Bitrate Communication Systems
