DP83867CR: transformer

Jeff YANG

Part Number: DP83867CR

Hi,

DP83687 (A PHY) connects to the transformer, then to B PHY.
For the B PHY side, does the Bob Smith termination need to be modified, or can the standard Bob Smith termination be used as-is?

Thanks!

The B PHY transformer design will be the same as U45.

Thanks

Hi David,

You mean it needs to be modified as shown in the diagram below, with a 0.1 µF capacitor connected?

Thanks!

Hi Jeff,

No, you can keep the 75 ohm resistors as is.

Best,
