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 the CC1350
SimpleLink Wireless MCU Silicon Errata 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.
