6 years agoHi Penn,
The soft CDR should be implemented after PMA CDR as it's soft logic design. It's impossible for user can't add any design on the hard circuit transceiver channel.
Rx data is expected to pass through PMA CDR -> soft CDR but I didn't look into the reference design detail implementation as well.
If you unzip the reference design, then you will find reference design.qar and also doc explaining on the design with design owner contact. Feel free to contact the Europe FAE directly which is also the design owner if you wish to understand more on the design.
Thanks.
