Semtech Adds 300MHz-510MHz Transceiver and Receiver to ISM Band RF Platform

The SX1212 is a single-chip transceiver that operates in the 300MHz to 510MHz frequency range with a receive current of only 2.5 mA (typ). The SX1213 is a single-chip receiver for the same frequency range and with the same low receive current level. Both devices are designed for wireless alarm, security, sensors network in home automation and automated meter reading applications.

“The low receive current of the SX1212 and SX1213 removes a limiting factor to the wireless control industry, which we think will lead to breakthrough systems that make use of a high receiver on time,” said Marc Pegulu, Semtech Industrial Analog product line manager. “For example, next generation energy harvesting solutions can leverage these devices in motion detectors and wireless remote controls to provide improved lighting smart controls that can optimize light levels for a perfect balance of energy consumption and productivity.” Semtech said its SX1212 and SX1213 are regulated to deliver a consistent RF range as the battery voltage decreases over time. This eliminates the cost and board space needed for external power management. For outdoor applications in extreme conditions, both devices leverage improved Semtech technology to deliver stable RF performance across a -40 degrees C to +85 degrees C temperature range.

Both devices incorporate a baseband modem with data rates up to 200 Kbit/s. Data handling features include a sixty-four byte FIFO, packet handling, automatic CRC generation and data whitening. All RF communication parameters are programmable and most of them may be dynamically set. Both devices comply with European (ETSI EN 300-220 V2.1.1) and North American (FCC part 15.247 and 15.249) regulatory standards.

With support for both frequency-shift keying (FSK) modulation and on-off keying (OOK) modulation, the SX1212 and SX1213 can be used in new and legacy sensor network designs. The devices support FSK data rates from 1.56 to 200 Kbit/s and OOK data rates up to 32 Kbit/s. Receiver sensitivity for FSK modulation is -104 dBm at 25 Kbit/s and for OOK is -110 dBm at 2 Kbit/s.

The SX1212 is available immediately. The SX1213 is also available immediately, the company noted in a release.
