SX1211_08 Datasheet, PDF (1/92 Pages) Semtech Corporation – Ultra-Low Power Integrated UHF Transceiver

ADVANCED COMMUNICATIONS & SENSING
General Description
The 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 (3mA in receiver
mode). It incorporates a baseband modem with data
rates up to 200 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 whilst 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.
