CPRI MegaCore Function User Guide is a user guide for CPRI MegaCore Function, which is released for Altera Complete Design Suite 12.0. It introduces the general description, interface, design flow and user guide of CPRI MegaCore Function.
The Altera CPRI MegaCore Function implements the Common Public Radio Interface (CPRI) V4.2 specification, designed for network radio equipment controllers (REC) and remote radio equipment (RE). It provides access to Layer 1 and Layer 2 of the CPRI specification through various interfaces, including IQ data access via MAP antenna-carrier interfaces, auxiliary interfaces for full user data plane access, Ethernet channels, and HDLC channels.
The document details the design flow using the MegaWizard Plug-In Manager, parameter settings for physical and data link layers, and the functional architecture including clocking structures and reset requirements. It also covers testing features such as loopback modes and PRBS generation, along with software interface registers and timing constraints for implementation.
