CPRI IP Core Auto-Rate Negotiation Does Not Support 614.4 Mbps Line Rate in Cyclone IV GX Devices - CPRI IP Core Auto-Rate Negotiation Does Not Support 614.4 Mbps Line Rate in Cyclone IV GX Devices Description CPRI MegaCore function variations that target a Cyclone IV GX device cannot achieve a CPRI communication line rate of 614.4 Mbps using auto-rate negotiation. This issue affects all CPRI MegaCore function variations with auto-rate negotiation enabled that target a Cyclone IV GX device. For these CPRI MegaCore function variations, auto-rate negotiation can change the CPRI communication line rate among 1228.8 Mbps, 2457.6 Mbps, and 3072.0 Mbps only. Resolution This issue has no workaround. This issue is fixed in version 10.1 of the CPRI MegaCore function.
