ZHCSIS3D September 2018 – June 2025 DP83869HM
PRODUCTION DATA
In applications where copper Ethernet interface is used, magnetic isolation is required. Magnetics can be discrete or integrated in the Ethernet cable connector. The DP83869HM operates with discrete and integrate magnetics if the magnetics meet the electrical specifications listed in Table 8-3.
