Subject: [802.3_B10GAUTO] PoDL MDI return loss update

 

FYI – following up on last Tuesday’s PoDL MDI return loss update preso.

 

I fabricated a 2x through test coupon and made some measurements where the impact on MDI return loss and insertion loss from a potential 1uH PoDL inductor was de-embedded based on the unpopulated 2x through test coupon. The results are summarized in the attached pdf file. Thanks.

 

Regards,
