1. About the CPRI IP

Updated for:
Intel® Quartus® Prime Design Suite 25.1
IP Version 19.10.0

The Common Public Radio Interface (CPRI) IP implements the CPRI Specification V7.0 (2015-10-09). CPRI is a high-speed serial interface for network radio equipment controllers (REC) to receive data from and provide data to remote radio equipment (RE).

The CPRI IP targets high-performance, remote radio network applications. You can configure the CPRI IP as an RE or an REC.

This user guide describes CPRI MAC layer information and does not cover information related to CPRI PHY. For related information:
