SINGLE CHIP 868MHZ TO 956MHZ RF TRANSCEIVER

MARCH 2008

REV. 1.0.0

FEATURES

GENERAL DESCRIPTION

• 2.2 to 3.6 Volt Operation

• 868 MHz to 956 MHz

The XR18W753 is a low-power, single-chip RF

transceiver designed to operate in license-free

European 868 MHz SRD, North American / Australian

• 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

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.

The device provides extensive hardware support for

packet handling such as frame timing, data buffering,

RSSI/ED/LQI for clear channel assessment, and FCS

and CRC hardware for error detection. TX output

power is programmable from -24 dBm to 0 dBm with

100 Kbps and 250 Kbps O-QPSK data supported.

• Fully integrated loop filter with few external

components needed (crystal, capacitors, antenna

and matching networks)

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

• 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

• Automatic meter reading

• Wireless sensor and telemetry networks
