Other Parts Discussed in Thread: DP83867CS

Hi,

My customer is considering DP83867CS.
DP83867CS is connected to other ether phy directly on the same board.
Would it be possible for them to connect to other phy without transformer?
#It is the following (2) like "Sigle Cap Isolation Topology".

Hello Taka-san,

The DP83867 has not been verified to work with capacitive isolation. The minimum solution would be a transformer between the two devices on the PCB.
