XR18W753 Single Chip 868MHZ to 956MHZ RF Transceiver
The XR18W753 is a single-chip RF transceiver designed to operate in license-free North American 915MHz ISM, European 868MHz SRD, and 950MHz to 956MHz bands for low-power, short-range wireless applications. Direct Sequence Spread Spectrum technique is employed to provide robust data communication in signal congested RF environments. The device provides extensive hardware support for packet handling, data buffering, packet timing, RSSI, energy detection, link quality indication, clear channel assessment, FCS computation, and CRC detection. RF ouput power is programmable from -24 dBm to 0 dBm with a maximum data rate of 250Kbps
