13 | | * The xps_ll_temac pcore has two ports for LocalLink clocks (LlinkTemac0_CLK and LlinkTemac1_CLK). These must be connected to the same clock signal which drives the SPLB_CLK ports on the corresponding xps_ll_fifo pcores. These signals are not connected automatically when you connect the LocalLink bus interfaces on the TEMAC and FIFO. |
14 | | * The TEMAC PHY type must be set to 1000Base-T (C_PHY_TYPE = 5). The other MGT-compatible PHY type (SGMII) didn't work with our SFP Ethernet modules. |
15 | | * The DCLK port on the xps_ll_temac core should be connected to a clock signal with frequency between 25 and 50MHz. It's unclear whether this signal is absolutely required for 1000Base-T modes (the Xilinx documentation is frustratingly vague), but our designs worked fine with a 40MHz DCLK. |
