DP83826I: Recommended pulse transmission

Ryuuichi machida

Part Number: DP83826I
Other Parts Discussed in Thread: DP83867E

Hello,

Let me confirm about your recommended pulse transmission spec.
When I check datasheet, I can understand only pulse tramsmission is necessory but there is no additional information how user choose this part.
Is there any application which describe about above ?

Hello,

We also have an FAQ on how to choose magnetics. You can crosscheck this methodology with the magnetic recommendations listed in datasheet.

Hello Gerome-san,

Thank you for your reply.
Actually, case of DP83867E, there is description in datasheet about required items for pulse transmission.
(In case of DP83867, table 9-1 show "Magnetic Isolation Requirements".)

However, in case of DP83826, there is no information about this on datasheet.
could you please confirm how I should crosscheck ?

Best regards,

Hello,

This table is in DP83826 datasheet, under Transformer Electrical Specifications. Regardless, the FAQ is valid for both tables to discern what is correct methodology to choose magnetics.
