DNT90MC DNT90MP - 900 MHz Frequency Hopping Spread Spectrum Transceivers - Direct Peer-to-peer Low Latency Communication - Transmitter Power Configurable to 40 or 158 mW - 100 kbps RF Data Rate - Serial Port Data Rate up to 250 kbps, SPI Port Data Rate up to 500 kbps Low Cost - 128-Bit AES Encryption - Separate Serial Port for Diagnostics 900 MHz FHSS - Analog and Digital I/O for Sensor Applications Transceiver - FCC and Canadian IC Certified for Unlicensed Operation Modules with The DNT90MC and DNT90MP FHSS transceiver modules provide a low-cost, versatile solution for I/O wireless data communications in the 900 MHz ISM band. Direct peer-to-peer communication pro- vides very low transmission latency between all modules in a network. The DNT90MC/MP RF out- put power can be set at 40 or 158 mW. The DNT90MC/MP receiver input is protected by a low-loss SAW filter, providing an excellent combination of receiver sensitivity and out-of-band interference rejection. The DNT90M module includes analog, digital and serial I/O, providing the flexibility to serve applications ranging from cable replacements to sensor networks. The DNT90MC/MP trans- ceiver module is easy to integrate and provides reliable wireless communications up to 5 miles in line-of-sight installations.
