Re: [802.3_B10GAUTO] AC coupling capacitors information

Hi Haysam,

   George Zimmerman suggested using 1MHz as the lower frequency limit to be consistent with 802.3ch.

   vakilian_3ch_01_0719.pdf in 802.3ch had PHY termination circuit values and board component assumptions for PoDL on slide 4.

   Thank you,

German Feyh

Hello, 

The discussion in moving the IL limit from 10MHz to 2MHz in accordance to https://www.ieee802.org/3/cy/public/nov21/feyh_3cy_01b_01_11_09_21.pdf.  I am looking for some information 

1. AC couple capacitor value range and ESR characteristics.
2. PHY termination circuit values 

This will help put together a simulation profile for the front end circuit.  

Best regards,
