Table 1. Common Clock/Reset Signals
Name Size I/O Description
sys_reset 1 I Reset for core.
dclk 1 I Stable input clk to GT.
gt_refclk_p 1 I Differential input clk to GT.
Note: This port is available when the Include GT subcore in core option is selected in the GT Selection and Configuration tab and the Include Shared Logic in core option is selected in the Shared Logic tab.
gt_refclk_n 1 I Differential input clk to GT.
Note: This port is available when the Include GT subcore in core option is selected in the GT Selection and Configuration tab and the Include Shared Logic in core option is selected in the Shared Logic tab.
tx_clk_out_* 1 O TX user clock output from GT.
Note:
  1. This port is available when the Select Core is Ethernet MAC+PCS/PMA 32/64-bit and the Include GT subcore in core option is selected in the GT Selection and Configuration tab.
  2. This port is available when the Select Core is Ethernet MAC+PCS/PMA 32/64-bit and GT type is GTM and Include GT subcore in example design option is selected in the Selection and Configuration tab.
tx_mii_clk_* 1 O TX mii clock output from GT.
Note: This port is available when Select Core is Ethernet PCS 32-bit.
tx_stats_clk_out_* 1 O 312.5 MHz / 125 MHz out put clock to be used for the tx statistic.
rx_stats_clk_out_* 1 O

312.5 MHz / 125 MHz out put clock to be used for the rx statistics.
rx_clk_out_* 1 O RX user clock output from GT.
tx_reset_* 1 I TX reset input to the core.
user_tx_reset_* 1 O TX reset output for the user logic.
rx_reset_* 1 I RX reset input to the core.
user_rx_reset_* 1 O RX reset output for the user logic.
gtpowergood_out_* 1 O Refer to the UltraScale Architecture GTH Transceivers User Guide (UG576) for the port description.
rxrecclkout_* 1 O RX recovered clock output from GT.
Note: This port is available when the Include GT subcore in core option is selected in the GT Selection and Configuration tab.
ctl_gt_reset_all_* 1 O gt_reset_all signal from the AXI4-Lite register map.
Note: This port is available when the Include AXI4-Lite is selected from the Configuration tab and the Include Shared Logic in example design option is selected in the Shared Logic tab (for non-Versal device only).
ctl_gt_tx_reset_* 1 O gt_tx_reset signal from the AXI4-Lite register map.
Note: This port is available when the Include AXI4-Lite is selected from the Configuration tab and the Include Shared Logic in example design option is selected in the Shared Logic tab (for non-Versal device only).
ctl_gt_rx_reset_* 1 O gt_rx_reset signal from the AXI4-Lite register map.
Note: This port is available when the Include AXI4-Lite is selected from the Configuration tab and the Include Shared Logic in example design option is selected in the Shared Logic tab (for non-Versal device only).
gtpowergood_in_* 1 I Refer to the UltraScale Architecture GTH Transceivers User Guide (UG576) or UltraScale Architecture GTY Transceivers User Guide (UG578) for the port description.
Note: For Versal device only.
apb3clk_* 1 I Refer to the UltraScale Architecture GTH Transceivers User Guide (UG576) or UltraScale Architecture GTY Transceivers User Guide (UG578) for the port description.
Note: For Versal device only when timestamp is enabled.
