The clock and data connections between the ILKNF transceiver interface and the GT transceivers varies depending on the selected GT technology and the configured operating mode. This section describes the connectivity between the ILKNF and the GT transceivers.
Note: In this table,
<N> is the SerDes data bus number 0 to 23.
| Port Name | Clock Domain | I/O | Description |
|---|---|---|---|
| tx_serdes_data<N>[79:0] | tx_serdes_clk[0] / tx_alt_serdes_clk[0] | O | In Interlaken mode, this is the data bus to the serial transceiver. |
| tx_fec0_slice0_dout_start | tx_serdes_clk[0] / tx_alt_serdes_clk[0] | O | When configured for ILKN+FEC mode, indicates start of codeword on tx_serdes_data0. |
| tx_fec1_slice0_dout_start | tx_serdes_clk[0] / tx_alt_serdes_clk[0] | O | When configured for ILKN+FEC mode, indicates start of codeword on tx_serdes_data2 (c0_ctl_tx_serdes_intf_mode[0] = 1) or tx_serdes_data4 (c0_ctl_tx_serdes_intf_mode[1] = 1). |
| tx_fec2_slice0_dout_start | tx_serdes_clk[0] / tx_alt_serdes_clk[0] | O | When configured for ILKN+FEC mode, indicates start of codeword on tx_serdes_data4 (c0_ctl_tx_serdes_intf_mode[0] = 1) or tx_serdes_data8 (c0_ctl_tx_serdes_intf_mode[1] = 1). |
| tx_fec3_slice0_dout_start | tx_serdes_clk[0] / tx_alt_serdes_clk[0] | O | When configured for ILKN+FEC mode, indicates start of codeword on tx_serdes_data6 (c0_ctl_tx_serdes_intf_mode[0] = 1) or tx_serdes_data12 (c0_ctl_tx_serdes_intf_mode[1] = 1). |
| tx_fec4_slice0_dout_start | tx_serdes_clk[0] / tx_alt_serdes_clk[0] | O | When configured for ILKN+FEC mode, indicates start of codeword on tx_serdes_data8 (c0_ctl_tx_serdes_intf_mode[0] = 1) or tx_serdes_data16 (c0_ctl_tx_serdes_intf_mode[1] = 1). |
| tx_fec5_slice0_dout_start | tx_serdes_clk[0] / tx_alt_serdes_clk[0] | O | When configured for ILKN+FEC mode, indicates start of codeword on tx_serdes_data10 (c0_ctl_tx_serdes_intf_mode[0] = 1) or tx_serdes_data20 (c0_ctl_tx_serdes_intf_mode[1] = 1). |
| rx_serdes_data<N>[79:0] | rx_serdes_clk[0] / rx_alt_serdes_clk[0] | I | In Interlaken mode, this is the data bus from the serial transceiver. |
