Webpath from fo_r to TX_Data is not constant and exceeds the frequency period (from 5 to 8ns), using Fast Output Register this value is 0.7ns I can not ignore this warning, because of … WebSo when you set the output delay (max) to 1.5ns you're saying Tsu + Te is 1.5ns, meaning the FPGA has Tclk - 1.5ns = 2.5ns to get your data from the output register to the FPGAs output pin. Which may be tight or may be trivial depending on the FPGA. What you aren't telling the tools is what the latency difference is between your two clocks.
