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