This is a 64-bit bus that runs at 156 MHz for 10 Gbps or up to 187. Basically, you can think of the SFP+ to BASE-T module as a media converter - it receives 10GBASE-R on one end, and produces 10GBASE-T on the other end, and vise versa. These characters are clocked between the MAC/RS and the PCS at. 3D supported. Need to account for the synchronization delay in PHY in the Bit Budget calculation. If you set the value of the Ethernet PCS interface parameter in the CPRI parameter editor to GMII, your IP core includes this interface.
