RF SDK targets small cell and backhaul developers

June 10, 2014 // By Jean-Pierre Joosting
Texas Instruments has added the RF Software Development Kit (RFSDK) to its Base Station SoftwarePac, enabling small cell developers to configure the baseband-to-radio communication and achieve first call or system verification in just one day compared to the weeks or months it took previously.

With the RFSDK, the KeyStone™-based TCI6630K2L small cell System-on-Chip (SoC) and TCI6631K2L backhaul SoC can now seamlessly implement digital radio functions like digital pre-distortion (DPD) and crest factor reduction (CFR), and use a JESD204B interface to communicate with the company's analog front end transceiver, the AFE7500, to maximize performance and system power efficiency. In addition, the RFSDK enables the TCI6630K2L SoC to communicate with analog high speed data converters from TI for industrial applications.

The RFSDK speeds customers' time-to-market by providing a complete integration code that connects to the company's baseband processor and RF ICs. By providing simple APIs and a web-like interface, the RFSDK abstracts hundreds of radio specific parameters into easy to use system level configurations. In deployment, the RFSDK provides OEMs and operators with the ability to field debug by monitoring and measuring the complete radio chain which is critical in SON deployments.

The TCI6631K2L SoC integrates two ARM® processor cores with four TMS320C66x DSP cores with a fully configurable Digital Radio Front End (DRFE) and more than a dozen radio and packet accelerators. This SoC can interface directly with the AFE7500 integrated Analog Front End (AFE) via JESD204B. This two-chip combination can form the basis for multiple radio solutions from 400 MHz to 4 GHz with off-the-shelf SDR implementations for LTE, LTE-U, WiMAX, Wi-FAR as well as proprietary implementations.
