SNLS614A September 2018 – December 2018 DP83869HM
The DP83869HM supports the 100BASE-TX standard as defined by the IEEE 802.3 standard. In 100M mode, the PHY will use two MDI channels for communication. The 100BASE-TX can work in Auto-Negotiation mode or in force mode. The PHY can be configured in 100BASE-TX through the register settings (Register Configuration for Operational Modes) or strap settings (Strap for DP83869HM Functional Mode Selection). When using DP83869 in force 100Base-TX mode, it is required to enable Robust Auto-MDIX feature from register 0x1E.
