Hi Rain,
I think you could be referring to VOD_DB instead. I checked and i cannot find VOD_EB in DS80PCI810 data sheet.
Please note DS80PCI810 does not support de-emphasis on it's outputs. If this function is required, please consider DS80PCI800 device.
VOD_DB refers to the VOD level on channel B outputs(OUTB signals)

Hi Nasser
thanks reply .
but I' m not mean VODA,VODB ,I mean VOD_DB and VOD ,these two feature is independent and individually controllable
My question is what is the difference between VOD_DB and VOD.
Another question is the SI model is common file (attched) ,for the output parameter ,just could control de-emphasis ,and VOD
but DS80PCI810 is not support for de-emphasis ,but it should have VOD_DB setting ,but only VOD can be adjusted.
VOD and VOD_DB act in a very similar way for the DS80PCI810. For this reason the VOD_DB is recommended to be set to 000'b. Setting the VOD_DB to other settings will reduce the overall amplitude. The VOD control provides enough control to the output amplitude for all PCIe applications.
