SNLS638A December 2018 – August 2019 DP83825I
The DP83825I provides an option to enable repeater mode functionality to extend the cable reach in un-managed mode (without the need of additional register configuration). Two DP83825I can be connected in back-to-back mode without any external configuration. It provides a Hardware Strap to configure the CRS_DV pin of RMII interface to RX_DV pin for back-to-back operation. Figure 11 shows the RMII pin connection that can enable DP83825I Repeater mode. If using managed mode, external Reset to both PHYs will be triggered at the same time.
