8.7. Transmitter Pre-Emphasis Analog Settings

The programmable pre-emphasis block in the transmit buffer amplifies the high frequencies in the transmit data to compensate for attenuation in the transmission media.

Note: Ignore all the pre-emphasis QSF assignments for PCIe* Gen1 and Gen2 if your transceiver link is within the PCI Express* spec requirements. Quartus Prime assigns default values for these parameters.
