Semtech XE1205

Semtech XE1205

TrueRF™ Multi-Channel, Narrow-Band RF Transceiver

The XE1205 is an integrated transceiver operating in the 433, 868 and 915 MHz license-free ISM (Industrial, Scientific and Medical) frequency bands; it can also address other frequency bands in the 180-1000 MHz range. Its highly integrated architecture allows for minimum external components while maintaining design flexibility.

Features

  • Programmable RF output power: up to +15 dBm
  • High Rx sensitivity: down to -121 dBm at 1.2 kbit/s,-116 dBm at 4.8 kbits.
  • Low power: RX=14 mA; TX = 62 mA @ 15 dBm
  • Can accommodate 300-1000 MHz frequency range
  • Wide band operation: up to 304.7 kbit/s, NRZ coding
  • Narrow band operation: 25 kHz channels for data rates up to 4.8 kbit/s, NRZ coding; optional transmitter pre-filtering to enable adjacent channel power below -37 dBm at 25 kHz
  • On-chip frequency synthesizer with minimum frequency resolution of 500 Hz
  • Continuous phase 2-level FSK modulation
  • Incoming data pattern recognition
  • Built-in Bit-Synchronizer for incoming data and clock synchronization and recovery
  • FEI (Frequency Error Indicator) with built-in AFC
  • RSSI (Received Signal Strength Indicator)
  • 16-byte FIFO for transmit / receive data buffering and transfer via SPI bus

Applications

  • Narrow-band and wide-band security systems
  • Voice and data over an RF link
  • Process and building control
  • Access control
  • Home automation
  • Home appliances interconnection
