LoRa Core™ Digital Baseband Chip for LoRaWAN® Network Gateways With Fine Timestamp Capability Overview The SX1303 is a new generation of LoRa® baseband processor for gateways. It is size and pin compatible with SX1302 and like SX1302, it excels in cutting down current consumption, simplifying thermal design, lowering Bill Of Materials cost, and reducing overall size of gateways. In addition to supporting all the features of SX1302, SX1303 introduces a new Fine Timestamp capability that enables Time Difference of Arrival (TDOA) network-based geolocation. Features Fine Timestamp Up to -141dBm sensitivity with SX1250 Tx/Rx front-end 125kHz LoRa reception with: 8 x 8 channels LoRa packet detectors 8 x SF5-SF12 LoRa demodulators 8 x SF5-SF10 LoRa demodulators Up to 8 packets can be received simultaneously when Fine Timestamp is enabled 125/250/500kHz LoRa demodulator (G)FSK demodulator Direct interface to Semtech transceivers SX1250, SX1255 and SX1257 Single 32MHz clock
