CPRI I/Q Switch

General Description

The CPRI I/Q Switch IP core is a cost and resource efficient silicon agnostic implementation of a CPRI I/Q Switch targeting any ASIC, FPGA or ASSP technologies. The switch makes it possible to connect multiple radio units with multiple baseband resources and performs routing at AxC level. Through an AXI4-Lite interface, the switch can dynamically be configured for 1:1, broadcast and multicast operation. The CPRI Ethernet C&M frames are routed in an embedded Ethernet switch IP. The CPRI I/Q Switch is designed for C-RAN and digital DAS systems.
