General Description
December 2010 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 MegaCore function targets high-performance, remote, radio network
applications. You can configure the CPRI MegaCore function as an RE or an REC.
Figure 1–1
Optical links between devices support high performance.
The CPRI MegaCore function includes interfaces to communicate between RE and
REC (the CPRI link), to communicate with RF (IQ data channels), to communicate
with a routing layer for daisy chain topologies, to communicate with a processor for
register updates, and to support High-Level Data Link Control (HDLC) and Ethernet
communication. You configure the CPRI MegaCore function to support either
Ethernet communication with an Ethernet media access control (MAC) block
included in the MegaCore function, or communication with an external Ethernet
module. The CPRI link line rate is configurable. For information about these interfaces
