eCPRI Altera® FPGA IP
The enhanced Common Public Radio Interface (eCPRI) Altera® FPGA IP core implements the eCPRI specification version 2.0.
Overview
The enhanced Common Public Radio Interface (eCPRI) Altera® FPGA IP core implements the eCPRI specification version 2.0. It is a front-haul interface protocol for radio base stations aimed at connecting the eCPRI Radio Equipment Control (eREC) and the eCPRI Radio Equipment (eRE) via front-haul transport network.
Key features
- Compliant with the eCPRI Specification V2.0 (2018-06-25) available on the CPRI Industry Initiative (CII) website.
- 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 Altera® FPGA IP with O-RAN Altera® FPGA IP.
