T2M Ethernet eCPRI Controller IP

eCPRI Controller IP

Description and Features

eCPRI Controller interface provides full support for the two-wire eCPRI Controller synchronous serial interface, compatible with eCPRI specification v2.1. Through its eCPRI Controller compatibility, it provides a simple interface to a wide range of lowcost devices. eCPRI Controller IP is proven in FPGA environment.The host interface of the eCPRI Controller can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol. eCPRI Controller IP is supported natively in Verilog and VHDL.
