3.4. Connecting the PCS to the HSSI Interface
In 32-bit PCS-Direct mode, the interface between the PCS and HSSI PHY maps as following:
TX Port Function | TX Port | RX Port Function | RX Port |
---|---|---|---|
Configuration-32, PMA Width-32, FPGA Fabric width-32 | |||
data[31:0] | tx_parallel_data[31:0] | data[31:0] | rx_parallel_data[31:0] |
tx_fifo_wr_en | tx_parallel_data[79] | rx_prbs_err | rx_parallel_data[35] |
rx_prbs_done | rx_parallel_data[36] | ||
rx_data_valid | rx_parallel_data[79] |
