This 3GPP Release 13 compliant NB-IoT UE Cat NB1 solution includes a Digital Modem integrated with a Protocol Stack (L1/L2/L3) SW, designed for the development of very low cost/power SoCs.
The SW has very low memory and low power footprint enabling easy integration to custom target platforms using ARM M series, MIPS or other CPU.
This solution has been integrated with 3rd party RFs.
The reference design is implemented on a Xilinx Zynq 7020 off the shelf EVK integrating the Digital Modem & Protocol Layer stack SW onto the embedded ARM Cortex CPU driving an ADI SDR RF transceiver.
