GENERAL DESCRIPTION
   The XR18W753 is a low-power, single-chip RF transceiver designed to operate in license-free European 868 MHz SRD, North American / Australian 915 MHz ISM bands. Digital I/Q modulation, demodulation and direct sequence spread spectrum techniques were employed to provide robust data transmission in signal congested RF environments.

FEATURES
• 2.2 to 3.6 Volt Operation
• 868 MHz to 956 MHz
• Direct-Sequence-Spread-Spectrum Transceiver
• Direct-up-conversion I/Q modulator
• Low-IF I/Q digital receiver
• Superior blocking/desensitization performance
• RSSI / ED / LQI for clear channel assessment
• FCS computation and CRC for error detection
• Low BOM cost and ease of production
• I2C Interface to data buffer and internal registers
• Fully integrated loop filter with few external
   components needed (crystal, capacitors, antenna
   and matching networks)
• Programmable TX output power in 3 dB steps
• Receiver sensitivity of -94 dBm at 100 Kbps
• Supports O-QPSK 100 Kbps and 250 Kbps data
• Industrial temperature (-40 to +85 oC)
• 48-pin QFN package

APPLICATIONS
• Industrial/Home automation, monitoring and control
• Point of sales and data collection terminals
• Entertainment, game, toy, robot, and remote control
• Active RFID, asset tracking and keyless entry
• Lighting, HVAC energy management
• Automatic meter reading
• Wireless sensor and telemetry networks
