Ultra-Low Power Integrated 300-510MHz Transceiver

Overview

TopologyOther Topology
IC revision2

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 powerconsumption (3mA in receiver mode).

It incorporates a baseband modem with data rates up to 150 kb/s. Datahandling 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 (ETSIEN 300-220 V2.1.1) and North American (FCC part 15.247 and 15.249) regulatory standards.
