Semtech’s low-power 300MHz-510MHz transceiver and receiver for ISM RF Band

Semtech has announced the new SX1212 UHF transceiver and SX1213 UHF receiver devices for low power (<3mA) solutions for industrial, scientific and medical (ISM) RF Band.

The SX1212/ SX1213 is a single-chip transceiver/ receiver with operating frequency 300MHz to 510MHz and receive current level is 2.5 mA (typ). And both the devices are targeted for wireless alarm, security, sensors network in home automation and automated meter reading applications.

They complement the SX1211, a transceiver that operates in the 863-960 MHz frequency range and features a receive current of less than 3.0 mA. All of the products are pin compatible.

Key features are,

RSSI (Received Signal Strength Indicator) range from Rx noise floor to 0 dBm
Bit rates up to 200 kb/s, NRZ coding
On-chip frequency synthesizer
Incoming sync word recognition and packet handling with CRC.
Built-in Bit-Synchronizer for incoming data and clock synchronization and recovery
Low Battery Detector
Optimized Circuit Configuration for Low-cost applications

“The low receive current of the SX1212 and SX1213 removes a limiting factor to innovation in the wireless control industry, which we think will lead to breakthrough systems that make use of a high receiver on time,” said Marc Pégulu, 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.”

The SX1212 and SX1213 are regulated and deliver RF range as the battery voltage decreases over time. Both devices incorporate a baseband modem with data rates up to 200 Kbit/s and the data handling features include a sixty-four byte FIFO, packet handling, automatic CRC generation and data whitening. 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 the support of 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.
