SINGLE CHIP 868MHZ TO 956MHZ RF TRANSCEIVER MARCH 2008 REV. 1.0.0 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. 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...
