Communications Infrastructure KeyStone System-on-Chip



The TMS320TCI6618 Communications Infrastructure SoC is a member of the KeyStone family of devices. It is based on TI's KeyStone multicore SoC architecture which uses the C66x DSP core. Designed specifically for multi standard 2G, 3G and 4G operation, the TCI6618 delivers double the LTE performance of previous solutions, while reducing SoC power consumption for macro and compact base stations to 0.075 mW/GMAC of power. Based on a 40-nm process technology, the TCI6618 macro basestation platform delivers 4.8 GHz of DSP processing power to support wireless standards including WCDMA/HSPA/HSPA+, TD-SCDMA, GSM, TDD-LTE, FDD-LTE, and WiMAX.
