General Description
May 2011 Altera Corporation
The Altera
Interface (CPRI) specification. CPRI is a high-speed serial interface designed for
network radio equipment controllers (REC) to receive data from and provide data to
remote radio equipment (RE).
The CPRI IP core targets high-performance, remote, radio network applications. You
can configure the CPRI IP core as an RE or an REC.
system implementation with a two-hop daisy chain. Optical links between devices
support high performance.
The CPRI IP core includes interfaces that perform the following functions:
■
■
■
■
■
Communicate between RE and REC (the CPRI link)
Communicate with RF (IQ data channels)
Communicate with a routing layer for daisy chain topologies
Communicate with a processor for register updates
Support high-level data link control (HDLC) and Ethernet communication
