CPRI Switch

General Description

The CPRI I/Q cross connect IP core is a ressource efficient non blocking silicon agnostic implementation of a 36x36 port CPRI I/Q cross connect targeting any ASIC, FPGA or ASSP technologies. The cross connect makes it possible to connect multiple radio units with multiple baseband ressources. Through an AXI4-Lite interface the cross connect can dynamically be configured for 1:1, broadcast and multicast operation. The cross connect enables routing at AxC level and does interface with Comcores and Xilinx CPRI implementations. The CPRI Ethernet Control and Management frames are assumed routed outside the I/Q cross connect in a separate Ethernet switch IP also delivered by Comcores. The cross connect is designed for C-RAN, digital DAS or advanced test systems.
