eCPRI Intel® FPGA IP

eCPRI IP in 5G Wireless Technology

The enhanced Common Public Radio Interface (eCPRI) Intel® FPGA IP core implements the eCPRI Specification Version 2.0. The eCPRI IP is a fronthaul interface protocol for radio base station aimed at connecting the eCPRI Radio Equipment Control (eREC) and the eCPRI Radio Equipment (eRE).

eCPRI is primarily used for 5G wireless communication systems. 

Features

 

The eCPRI Intel® FPGA IP core offers the following features:

  • Compliant with the eCPRI Specification V2.0 (2019-05-10) available on the CPRI Industry Initiative (CII) website supporting Type0 Interworking Function (IWF) 
  • Supports eCPRI radio equipment controller (eREC) and eCPRI radio equipment (eRE) module configurations
  • Supports Ethernet headers in a variety of formats, including VLAN tag, source/destination MAC address, IPv4, UDP extraction and encapsulation
  • Supports eCPRI one-way delay measurement based on IEEE Standard 1588 Precision Time Protocol (1588 PTP) hardware timestamp. Full hardware support, and required 1588 PTP software stack. Supports 25 Gbps and 10 Gbps Ethernet ports
  • Supports pairing of eCPRI Intel FPGA IP with external O-RAN IP
