You don't need to use multiple clock domains to use the 10GbE block. Afaik, the 10GbE yellow block already handles the clock mismatch for you. You do need to make sure that you're not feeding the yellow block at a faster data rate than it can handle. If you do, you'll start seeing tx_overflow go high. Billy
