Hi,
I was primarily thinking of implementing the DDIO logic in FPGA fabric which involves an asynchronous mux in the output. We had also alt_ddio available with previous FPGA families. With Agilex you have GPIO IP in DDIO mode available.

Hi Frank :
Thanks for your Method,
One More Question is
" If We use 8bits parellel SERDES TX IP (Lowest Data Rate is 600Mbs), the 8bits Parallel Data Clock is Only 600/8 = 75MHz,
but the Method you suggested for 192Mbps LVDS Function use DDR IO IP. the Data Clock will be 96MHz"
Are you Sure that agilex5 FPGA can Support 96MHz Clock Speed after we use Quartus Prime-Pro 24.3 Edition tool to
Synthesize & Optimization our Digital Design.
If the Maximum clock Speed can Reach 96Mhz after Quartus Prime-Pro 24.3 Edition tool Synthesize & Optimization our
Digital Design, I think the 8bits Parallel Data Clock is Only 600/8 = 75MHz will be a better solution, because its clock Rate is
Only 75Mhz.
How do you think my opinion !?...
thanks for your technique opinion.
