Product Details


  • Highly integrated solution for the 315/434/868/915 MHz band
  • Very few external components required
  • Complies with ETSI EN300-220/FCC part 15 standards
  • Near zero-IF RX architecture
  • On-chip channel filtering with automatic calibration supported to provide stable cut-off frequencies and filter roll-off
  • Multi-channel TX and RX operation by fully integrated fractional-N PLL with on-chip loop filter
  • Automatic VCO sub-band selection and calibration to reduce PLL loop bandwidth variation
  • Programmable ASK/FSK modulation with Manchester codec
  • Programmable transmitter output power (-20 dBm to +10 dBm), stabilized with onboard PA regulator
  • Digital RSSI with a configurable threshold
  • Onboard Signal Signature Recognition Unit (SSRU) with Preamble Pattern Recognition (PPR)
  • Configurable RX polling timer with 2 % absolute accuracy
  • Level Sensitive Data (LSD) slicer with self-adjusting threshold
  • Low power consumption (RX 16 mA, TX 13 mA at 6 dBm), with ultra Low 0.5 μA standby current and configurable polling timer
  • Single lithium cell operation (2.1 V). Operation up to 3.6 V fully supported
  • 32-Pin HVQFN32 Pb-free package
