Line-rates up to 8.5 Gb/s
If both ends of the link are 7 series FPGAs GTH transceivers, the link margin degradation could be up to 0.1 UI.
Line-rates above 8.5 Gb/s
If both ends of the link are 7 series FPGAs GTH transceivers, the link margin degradation could be up to 0.2 UI.
Supported Use Modes
For GTH transceiver line rates above 8.5 Gb/s and up to 10.3125 Gb/s, the maximum supported channel loss at Nyquist frequency is 25 dB when using the latest DFE attribute settings (PMA_RSV2, RX_BIAS_CFG, RXDFEXYDEN) in (Xilinx Answer 47128). Otherwise, the maximum supported channel loss is 20 dB.
For GTH transceiver line rates above 10.3125 Gb/s and up to 11.3 Gb/s, the maximum supported channel loss at Nyquist frequency is 20 dB.
