SX1302 LoRa Gateway Baseband Transceiver W/ , Z >Z W/ & y y W , >Z D, >Z , W , y y & <>Z d W/ Figure A: Block Diagram General Description Key Features The SX1302 is a new generation of baseband LoRa chip for LoRaWAN, Class A/B/C, all regions gateways. It excels in reducing current consumption, 125 kHz LoRa reception with: simplifies the thermal design of gateways, and reduces the 8 x 8 channels LoRa packet detectors Bill Of Materials costs, yet it is capable of handling a higher 8 x SF5-SF12 LoRa demodulators amount of traffic than preceding devices. 8 x SF5-SF10 LoRa demodulators 125 /250 / 500 kHz LoRa demodulator The high-speed baseband digital engines are clocked from (G)FSK demodulator a single 32 MHz clock source, and the chip embeds the capability to support SF5 and SF6 unlike previous Direct interface to Semtech transceivers generations. To absorb the additional traffic that the radio SX1255, SX1257 and SX1250 will be able to detect, more modems are now collaborating. Single 32 MHz clock 8 of them have been added to specifically handle the high-speed SF5 and SF6 packets, whilst the 8 others are still Ordering Information taking care of the SF7-SF12 traffic. The architecture has been reworked to reduce power consumption very significantly it makes it easier to embed the SX1302 in Part Number Delivery Order Quantity highly-integrated environments where power dissipation SX1302IMLTRT Tape and Reel 3000 might be a challenge. The SX1302 is also serialized in production, with a globally unique 64-bit number.
