MOBILE WORLD CONGRESS --
As the mandate for capacity continues to skyrocket, networks carrying yottabits of traffic will become a reality in the not too distant future. To achieve this kind of capacity operators have begun deploying small cell wireless base stations to offer the best solution for backhaul connectivity. However, the wireless backhaul portion of the solution is well recognized as a challenge due to operators' rigorous demands on efficiency, range and performance.
Today, Texas Instruments (TI) (NASDAQ: TXN) is meeting these requirements with the industry's most flexible backhaul System-on-Chip (SoC), the
. TI's KeyStone
-based TCI6631K2L provides developers a common Software Defined Radio (SDR) programmable platform to address the varied configurations of wireless backhaul at a reduced system cost and power consumption. By combining the TCI6631K2L with an analog front end transceiver, the
, TI has developed a unique two-chip solution designed for scalability and adaptability to cover the Non-Line-of-Sight (NLOS) spectrum from TV white space (TVWS) (UHF/VHF) to 6GHz and Line-of-Sight (LOS) up to 86GHz.
Fully integrated analog + digital solution
As the backhaul market continues to evolve, developers are seeking solutions that offer the highest levels of integration with the flexibility to meet a variety of end product configurations. TI's TCI6631K2L two-chip wireless backhaul solution provides just that; a fully integrated analog and digital solution with a minimal footprint and power profile, enabling a complete design in a small package within a POE+ power footprint. The TCI6631K2L leverages the fastest dual ARM® Cortex® -A15 RISC processors and four of TI's fixed- and floating-point TMS320C66x digital signal processor (DSP) generation cores as part of TI's highly efficient KeyStone SoC architecture supporting L1/L2/L3 and transport processing.
The AFE7500 wireless radio transceiver is a state-of-the-art integrated RF-to-bits SoC. Supporting wideband 2X3 MIMO configuration with integrated data converters and PLLs, the AFE offers best-in-class performance to meet backhaul market needs. AFE7500 interfaces directly to TCI6631K2L via a standard JESD204B connection, allowing the use of digital radio front end (DRFE) features to gain better power amplifier efficiency while reducing board space and system cost. Additional features include auxiliary data converters (ADCs and DACs), temperature sensors and general purpose digital IOs.
