In section 8.4.1 of the datasheet on Pin Control Modes, can you provide additional details on the reason for removing the de-emphasis when enforced to GEN3 (tie 20k to GND) as opposed to FLOAT (AUTO rate) where de-emphasis in Gen3 is supported?

Hi,
In almost all cases removing the DEM function on the redriver helps system link equalization training algorithms. Having the two settings for this feature allows the user to customize the setup to produce the best system result.
