DP83822IF: Distance between IC and pulse transformer.

Guru 11245 points
Part Number: DP83822IF
Other Parts Discussed in Thread: TLK105

Hi team,

Inevitably, the distance between the ic and the pulse transformer will be far apart, causing noise problems.
Is there any countermeasure I can take other than reducing the distance?

Also, I switched back to TLK105 from DP83822 because of the delivery problem.
At this time, the problem of interference with the 400MHz antenna occurred.
Is there anything I can assume about the cause?

Sincerely.
Kengo.
