Hello,
I have taken a look at the magnetic requirements for this device and I need some help identifying parts for my specific design.
I have two questions
1. HX5008FNL is listed as the recommended solution for this device. Is it possible to use HX5008NL instead of HX5008FNL?
2. Are there any equivalent dual-port or quad-port magnetics that could be used with this device?

Hello Alvaro,
I have some follow up questions I am hoping you can help me with
The recommended transformer for this part (HX5008NL) does not meet the requirements that are listed on your datasheet. See the specs from this part that I will attach and the requirements from the datasheet... Note that the differential to common mode rejection is higher, as well as the crosstalk, even the return loss for the lower frequencies.
Do you have a table with the MAX allowed values? your datasheet only includes typical values.
As a side question, I am considering using H5012FNL as a dual port transformer for the design, My main concern is that the insertion loss is 1.4dB rather than the 1dB recommended in the datasheet. I would appreciate your help with both of these things.
1. What are the maximum values accepted for the magnetic parameters
2. Would H5012FNL work as a dual port solution?
Hi Karla,
The HX5008NL meets our spec.
Our spec for Differential to Common Mode Rejection is -30 for 1-50 MHz and -20 for 60-150 MHz .
The HX5008NL has a number much smaller (more negative). This is good and desired.
Funny enough, the HX5008NL is the transformer used in the DP83869 EVM Board.
Regards,
Alvaro
Alvaro,
I am referring to H5012FNL, this is a two port device, I understand you don't have any dual or quad port recommendations, but I found this part and need your help determining if it would work. As you can see in the image, the insertion loss is 1.4dB.
