9.2.2 Detailed Design Procedure

The DS125BR800 is designed to be placed at a location where the input CTLE can help to compensate for a portion of the overall channel attenuation. In order to optimize performance, the repeater requires tuning to extend the reach of the cable or trace length while also recovering a solid eye opening. To tune the repeater, the settings mentioned in Table 2 and Table 3 (for Pin Mode) are recommended as a default starting point for most applications. Once these settings are configured, additional tuning of the EQ and, to a lesser extent, VOD may be required to optimize the repeater performance for each specific application environment. Examples of the repeater performance as a generic high speed datapath repeater are illustrated in the performance curves in the next section.
