Reference clock for TSE - Reference clock for TSE Hello, I'm using an Arria V FPGA with an TSE IP. What dedicated clock should I use for the IP's "ref_clk" input. Is it REFCLK vs GXB_REFCLK ? Replies: Re: Reference clock for TSE Hi, For best performance, I always recommend to use dedicated Refclk pin which is "Refclk". GXB_Rx/GXB_Refclk is dual function shared pin where by default it will be used as transceiver Rx pin but user can also op to choose to use it as alternate Refclk pin when you don't have enough Refclk pins to use. (In this case, transceiver Rx function will be disable) Thanks. Regards, dlim
