tx_port<N>_serdes_cw_start O tx_port<N>_clk Indicates the start of a codeword pair on tx_port<N>_serdes_data_out
tx_port<N>_pcs_data_flow0[1284:0] I tx_port<N>_clk TX data input on flow 0
tx_port<N>_pcs_data_flow1[1284:0] I tx_port<N>_clk TX data input on flow 1
tx_port<N>_pcs_data_valid_flow0 I tx_port<N>_clk TX data input valid on flow 0 (active-High)
tx_port<N>_pcs_data_valid_flow1 I tx_port<N>_clk TX data input valid on flow 1 (active-High)
tx_port<N>_pcs_data_cw_start_flow0 I tx_port<N>_clk Codeword start pulse on flow 0
tx_port<N>_pcs_data_cw_start_flow1 I tx_port<N>_clk Codeword start pulse on flow 1
rx_port<N>_pcs_data_flow0[1284:0] O rx_port<N>_serdes0_clk RX data output on flow 0
rx_port<N>_pcs_data_flow1[1284:0] O rx_port<N>_serdes0_clk RX data output on flow 1
rx_port<N>_pcs_data_valid_flow0 O rx_port<N>_serdes0_clk RX data output valid on flow 0 (active-High)
rx_port<N>_pcs_data_valid_flow1 O rx_port<N>_serdes0_clk RX data output valid on flow 1 (active-High)
rx_port<N>_pcs_data_am_start_flow0 O rx_port<N>_serdes0_clk RX data output Alignment Marker presence flag on flow 0
rx_port<N>_pcs_data_am_start_flow1 O rx_port<N>_serdes0_clk RX data output Alignment Marker presence flag on flow 1
rx_port<N>_pcs_mark_bad_flow0 O rx_port<N>_serdes0_clk Indicates that the RX transcoder must mark data for this codeword pair as bad for flow 0
rx_port<N>_pcs_mark_bad_flow1 O rx_port<N>_serdes0_clk Indicates that the RX transcoder must mark data for this codeword pair as bad for flow 1
