DP83867IR: How to connect the cable line driver

Part Number: DP83867IR


Hi team,

Customer is confused about how to connect the cable line driver of DP83867IR, because there are different example schematics depending on devices.

Please see the attached ppt. Each schematics are different.

  • When customer wants to use DP83867IR, they should follow figure 30 of the datasheet?
  • And why the recommended schematics are different depending on devices?
  • When customer wants to use DP83867IR for PoE, can customer still follow on figure 30?

Regards,

Noriyuki Takahashi
