LPDDR4 Clock Trace impedance recommendation

[puneethkumar]

Dear Team,

In the Trace impedance recommendation for LPDDR4 ( other than differential) is 50 Ω Single-ended (DXL)

What is the recommended for differential signals - Whether we can use 100 Ω differential ?

Hello,

   Yes, according to preliminary recommendations, it is possible to
use 100 Ω differential for i.MX 8DXL.

 Note, i.MX 8DXL documentation is not published yet.

Regards,
Yuri.
