Connect tx_clkout (257.8125 MHz) of each individual channel to tx_coreclkin and connect rx_clkout (257.8125 MHz) to rx_coreclkin. If you use any other source for tx_coreclkin/rx_coreclkin, make sure tx_coreclkin and rx_coreclkin have 0 PPM difference with tx_clkout and rx_clkout, respectively. The clocking scheme in this use case is the same as PMA Direct 10G x 1.
