LogiCORE CPRI v2.3 - Virtex-6 FPGA GTX reference clock default is 122.88 MHz


The CPRI core defaults to using a 122.88 MHz reference clock when a design is generated for Virtex-6. CPRI operation at speeds of 2.4 Gbps and above might require a different reference clock selection.


Please read device errata and user guides, or contact Xilinx for guidance on selecting the correct reference clock.
