Vih and Vil parameters are not mentioned for the LVPECL input voltage in the FPGA Arria V datasheet.

I am working on the signal integrity using hyperlynx for the FPGA Arria V GX. I am performing one simulation for the LVPECL input voltage to the FPGA in which I got the Vih=2.38 V and Vil= 1.63 V. Bu...
