Other Parts Discussed in Thread: DP83867IR

Hi all

Would you mind if we ask DP83867IRPAPR?
Our customer would like to use following Pulse Trans.(which is producted by Pulse)
https://media.digikey.com/pdf/Data%20Sheets/Pulse%20PDFs/HX5008FNL.pdf

Is this suitable for DP83867IR?
Or, if you have recommendation, could you give us?

Kind regards,

Hello Matsumoto-san,

The HX5008FNL would be OK to use with the DP83867IRPAP.

A better magnetic to use is H5007NLT if the layout of the H5007NLT is acceptable.

Can I ask why you selected the DP83867IRPAPR instead of the DP83867IRRGZ? Are you using GMII?

Best Regards,

Thank you for your reply always.

->We heard that our customer will use GMII.

And then our customer asked us whether the following pulse-trans can use for DP83867IRPAPR or not.
<J0G-0001NL>

We guess that there is no turn-rartio and Inserttion loss -1.2dB is not enought.
Is our recognition correct?

Kind regards,

Matsumoto-san,

Your recognition of the insertion loss is correct. We recommend -1.1dB insertion loss and 1:1 2% turn ratio. I do not see turn ratio listed in the datasheet you have linked.
