ZHCSIS3C September 2018 – April 2024 DP83869HM
PRODUCTION DATA
The DP83869HM supports the 100Base-FX Fiber Ethernet protocol as defined in IEEE 802.3 standard. In 100M Fiber mode, the PHY will use two differential channels for communication. In fiber mode, the speed is not decided through auto-negotiation. Both sides of the link must be configured to the same operating speed. The PHY can be configured to operate in 100BASE-X through register settings (Section 7.4.8) or strap settings (Section 7.5.1.2).
