I am trying to use the GX transceiver on the GX starter board.
I've used the Mega wizard to generate a sgmii pcs/pma function. What I don't understand is how the GX pins connect to the sgmii module. I have gxp_clk , // 125Mhz differential clock pin M7 LVDS gxn_clk , // 125Mhz differential clock pin N7 LVDS rxp_data , // 1.4-V PCML pin E2 GXB_RX1 rxn_data , // 1.4-V PCML pin E1 GXB_RX1 txp_data , // 1.4-V PCML pin C2 GxB_TX1 txn_data , // 1.4-V PCML pin C1 GxB_TX1 The mega wizard generated module has .gxb_cal_blk_clk ( ), .ref_clk ( ), // MDI interface ?? .txp ( ), // MDI interface ?? .rxp ( ), // MDI interface ?? So how does the 6 GX pins connect to the 4 ports on the sgmii module ? Is there a specific instantiation of the GX ? How do I specify the GXB_1 transceiver ? Just by virtue of pin assignment ? I've looked at the TSE design example & cannot find any example of the hookup. TIA.Link Copied
