Product Overview

SM1211E915 is a 2 layer RF module operates at 915MHz band. The SX1211 is a low cost Single chip transceiver operating in the frequency ranges from 902-928MHz. The SX1211 is optimised for very low power consumption (3mA in receiver mode). It incorporates a baseband modem with data rates up to 200kb/s. Data handling features include a sixty four byte FIFO, packet handling, automatic CRC generation and data whitening. Its highly integrated architecture allows for minimum external component count whilst maintaining design flexibility. All major RF communication parameters are programmable and most of them may be dynamically set. It complies with European (ETSI EN 300-220 V2.1.1) and North American (FCC part 15.247 and 15.249) regulatory standards.
  • Low Rx power consumption of 3mA
  • Low Tx power consumption of 25mA at +10dBm
  • Good reception sensitivity is down to -107dBm at 25 kb/s in FSK, -113dBm at 2kb/s in OOK
  • Programmable RF output power is up to +12.5dBm in 8 steps
  • Packet handling feature with data whitening and automatic CRC generation
  • Wide RSSI (Received Signal Strength Indicator) dynamic range, 70dB from Rx noise floor
  • Bit rates up to 200kb/s, NRZ coding.
  • On-chip frequency Synthesiser
  • FSK and OOK modulation, Incoming sync word recognition
  • Built-in bit Synchronizer for incoming data and clock synchronisation and recovery
