Communications DSP meets multi-Gbit modem performance requirements

Able to meet the extreme performance requirements of multi-gigabit class modems, the CEVA-XC12 is purpose-built, says the company, to solve the most critical challenges of efficiently implementing 5G, gigabit LTE, MU-MIMO Wi-Fi and other multi-gigabit modems.

A new micro-architecture meets very high frequency requirements and low power consumption, enabling it to operate at 1.8GHz in 10nm. It delivers up to eight times performance improvement and consumes 50 per cent less power than its predecessor, the CEVA-XC4500, for a complete 5G baseband modem.

Technologies designed for wireless standards, such as 5G, will be capable of delivering a peak data rate of up to 20Gbit/s at a low latency of 1ms, using Massive-MIMO and advanced 3D dynamic beamforming processing techniques.

According to the company, the CEVA-XC12 is the industry’s first DSP architecture offering the raw performance and power efficiency needed for multi-gigabit class modems. Its flexible architecture with multiple optional features can be custom configured and scaled to address a range of applications, such as smartphones and other terminals, advanced and centralised access points, small cells, macro cells and cloud RAN (C-RAN). It supports 5G use cases and deployment scenarios, from 80GHz mmWave down to 450MHz spectrum bands. IT is also suited for the design of LTE-Advanced Pro Evolution, enhanced Mobile Broadband (eMBB), Licensed Assisted Access (LAA), MulteFire carrier aggregation and LWA (LTE/Wi-Fi Aggregation), cellular V2X, Wi-Fi 802.11ax, WiGig 802.11ad, Fixed Wireless Access (FWA) and Virtual Reality (VR) systems.
