eCPRI Controller IP
Design IP
Overview

SmartDV’s eCPRI (enhanced Common Public Radio Interface) Controller IP is a silicon-proven, high-performance solution tailored for 5G and next-generation wireless infrastructure. It enables efficient, low-latency transport of radio data between radio equipment (RE) and radio equipment control (REC) units, adhering to the latest eCPRI specifications defined by the CPRI Cooperation.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. It supports dynamic bandwidth allocation, low jitter communication, and seamless integration with Ethernet PHYs, making it ideal for scalable and high-capacity fronthaul network architectures.
