ADVANCED COMMUNICATIONS & SENSING
SX1212 Transceiver
Ultra-Low Power Integrated 300-510MHz Transceiver
General Description
The SX1212 is a low cost single-chip transceiver
operating in the frequency ranges from 300MHz to
510MHz. The SX1212 is optimized for very low power
consumption (3mA 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 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.
