PRODUCTION DATA
The line driver implementation is designed to support simple connections to the transformer and the connector. The DP83867 includes integrated terminations so no external termination resistors are required.
The connection diagram for the cable line driver is shown in Figure 8-2.
Magnetic isolation used with the DP83867 can either be a discrete solution or integrated with the RJ-45 connector. Refer to Table 8-1 for the electrical requirements.
