9.2.2 Detailed Design Procedure

The DS80PCI402 should be placed at an offset location and close to the Rx with respect to the overall channel attenuation. The suggested settings are recommended as a starting point for most applications. Once these settings are configured, additional adjustments of the DS80PCI402 EQ or DE may be required to optimize the repeater performance. The CTLE and DFE coefficient in the Rx can also be adjusted to further improve the eye opening.
