Title
Why is there a reconfig_clk frequency discrepancy between the device handbook and the Triple Speed Ethernet (TSE) User Guide?
Description
From the device handbook, reconfig_clk has a max frequency of 50 MHz. In the Altera® Triple Speed Ethernet (TSE) MegaCore® function User Guide 9.0, reconfig_clk is running at 125 MHz. Information regarding the reconfig_clk frequency range in the TSE User Guide is incorrect. You should follow the frequency range stated in device handbook.
You also need to manually change the assignment of fixedclk_fast signal in altera_tse_gxb_gige_inst to ‘0’. This will be fixed in a future release.
