All Silicon IP


CEVA has designed a complete eNB-IoT IP solution that can serve a wide range of applications. The CEVA-Dragonfly NB2 pre-integrates together a CEVA-X1 processor, an optimized RF Transceiver, baseband, and a protocol stack to offer a complete Release 14 Cat-NB2 modem IP solution that reduces time-to-market and lowers entry barriers. The CEVA-Dragonfly NB2 is a fully software-configurable solution that can be extended with multi-constellation GNSS and sensor fusion functionality. It includes a reference silicon of the complete modem design, including an embedded CMOS RF transceiver, an advanced digital front-end, physical layer firmware, and aprotocol stack (MAC, RLC, PDCP, RRC, and NAS).


  • Fully integrated silicon reference design for eNB-IoT and GNSS, lets customers focus on development and integration of application level software and use-case specific workloads with pre-integrated eNB-IoT modem
  • Reduces time-to-market and lowers entry barriers
  • Single-processor, software-configurable solution is guaranteed futureproof for future NB-IoT updates and enhancements
  • Supports addition of GNSS and Sensor Fusion workloads
