Other Parts Discussed in Thread: DP83867IR

Hi

My customer is considering DP83867IR for their platform in the future.
One of all their product is only required 10/100Base transmission. (not use 1000Base-T)

Plsase let me know about the magnetics.
My customer will use a HX1188FNL. Is there a problem? or Could you recommnend anything magnectics?
I couldn't find this requrird specfication on datasheet.

Taka,

We have seen the Pulse HX1188 used with success in applications with our other PHYs. It should be OK.

For this application, I would recommend strapping the DP83867IR so that it only advertises 10/100 capabilities via Auto-negotiation. This is accomplished by strapping SPEED_SEL1 = 1 and SPEED_SEL0 = 1.
