6.3 RF Core

The RF core is a highly flexible and capable radio system that interfaces the analog RF and baseband

circuits, handles data to and from the system side, and assembles the information bits in a given packet

structure.

The RF core can autonomously handle the time-critical aspects of the radio protocols, thus offloading the

main CPU and leaving more resources for the user application. The RF core offers a high-level,

command-based API to the main CPU.

The RF core supports a wide range of modulation formats, frequency bands, and accelerator features,

which include the following (not all of the features have been characterized yet, see for more information):

• Wide range of data rates:

– From 625 bps (offering long range and high robustness) to as high as 4 Mbps

• Wide range of modulation formats:

– Multilevel (G) FSK and MSK

– On-Off Keying (OOK) with optimized shaping to minimize adjacent channel leakage

– Coding-gain support for long range

• Dedicated packet handling accelerators:

– Forward error correction

– Data whitening

– 802.15.4g mode-switch support

– Automatic CRC

• Automatic listen-before-talk (LBT) and clear channel assist (CCA)

• Digital RSSI

• Highly configurable channel filtering, supporting channel spacing schemes from 40 kHz to 4 MHz

• High degree of flexibility, offering a future-proof solution

The RF core interfaces a highly flexible radio, with a high-performance synthesizer that can support a wide

range of frequency bands.
