2.10 HSSTOP Module

This module contains the Xilinx Aurora IP for transmitting bitplane data to the DLPC964 controller board. This protocal is called the Aurora 64b/66b and for more information, go to Section 4.3.

As shown in Figue 2-8, the HSSTOP module has an AURPRA_APPS_TX_X12LN wrapper for all four of the GTX channels. Each Aurora GTX channel is comprised of three lanes with each lane transmitting 10Gbps. To help keep the GTX lanes synchronized, all four of the channels share the same Aurora clock module.

The Aurora IP allows the differential signals to have a pre-emphasis and post-emphasis to help with signal integrity. In the DLPC964 Apps FPGA design, the following settings were used.

Signal Name Value
gt_txpostcursor_in 0.00dB (00000)
gt_txdiffctrl_in 807mV (1000)
gt_txmaincursor_in 0.00dB (00000)
gt_txprecursor_in 0.00dB (00000)
