GENERAL DESCRIPTION

The SX1223 is a single chip transmitter operating in UHF frequency bands including the 434, 869 and 915 MHz license-free ISM (Industrial Scientific and Medical) bands. Its highly integrated architecture allows for minimum external components while maintaining design flexibility. All major RF communication parameters are programmable and most of them can be set dynamically. The SX1223 offers the advantage of high data rate communication at rates of up to 153.6 kbit/s. The SX1223 is optimized for low cost applications while offering high RF output power. The device is suitable for applications which have to satisfy either the European (ETSI-300-220) or the North American (FCC part 15) regulatory standards.
