Product Brief 4&.5&$)"%7"/$&%$0..6/*$"5*0/44&/4*/( SM1211 Ultra Low Power Integrated UHF Transceiver Module General Description: Key Product Features: The purpose of this module is to provide a development platform of the SX1211. User can build his application prototype by simply connecting the module to his target microcontroller and start developing his application software. The SM1211 module integrates the SX1211 reference design (chip + external components) plus miscellaneous useful connectors. • Small form factor design footprint <150 mm2 Optimized Low-cost design – 2 layers PC-board • Low Rx power consumption: 3 mA • Low Tx power consumption: 25 mA @ +10 dBm • Good reception sensitivity: down to -107 dBm at 25 kb/s in FSK, -113 dBm at 2 kb/s in OOK • Programmable RF output power: up to +12.5 dBm in 8 steps • Packet handling feature with data whitening and automatic CRC generation • RSSI (Received Signal Strength Indicator) range from Rx noise floor to 0 dBm • Bit rates up to 200 kb/s, NRZ coding • On-chip frequency synthesizer • FSK and OOK modulation • Incoming sync word recognition • Built-in bit-synchronizer for incoming data and clock synchronization and recovery SX1211 is a low cost single-chip transceiver operating in the frequency ranges from 863-870, 902-928 MHz and 950-960 MHz. The SX1211 is optimized for very low power consumption (3 mA in receiver mode). It incorporates a baseband modem with data rates up to 150 kb/s. Data handling features include a sixty-four byte FIFO, packet handling, automatic CRC generation and data whitening. Its highly integrated architecture allows for minimum external component count while maintaining design flexibility. All major RF communication parameters are programmable and most of them may be dynamically set. It complies with European (ETSI EN 300-220 V2.1.1) and North American (FCC part 15.247 and 15.249) regulatory standards. Note: This module is also used for the SX1211 Starter Kit.
