ISM band RF ICs consume industry’s lowest receive current

ISM band RF ICs consume industry’s lowest receive current

Claimed to offer a receive current up to 6 times lower than the competition, the SX1212 UHF transceiver and SX1213 UHF receiver offer low-power solutions (less than 3 mA) for the entire ISM RF band. Both operate in the 300 to 510-MHz range and are designed for wireless alarm, security, and sensors network in home-automation and automated-meter reading applications.

The devices support FSK data rates from 1.56 to 200 kbits/s and OOK data rates up to 32 kbits/s. Receiver sensitivity for FSK modulation is –104 dBm at 25 Kbits/s and for OOK is –110 dBm at 2 Kbits/s. In addition, the chips comply with European (ETSI EN 300-220 V2.1.1) and North American (FCC Part 15.247 and 15.249) regulatory standards.

Housed in TQFN packages, they also feature incoming sync word recognition and packet handling with CRC and a built-in bit synchronizer for incoming data and clock synchronization and recovery. They complement the SX1211, a transceiver that operates in the 863 to 960-MHz frequency range and features a receive current of less than 3.0 mA. All of the products are pin compatible.
