Propagation delay speed of DDR3 in i.MX6Q SABRE-AI.

[keitanagashima]

I'd like to know the propagation delay speed of DDR3 lines in i.MX6Q SABRE-AI layout.

Could you give me blow information?

Layer 1 : propagation delay speed [mil/ps] of DDR3 lines (Single : 50 Ohm, Differential : 100 Ohm).

Layer 3 : propagation delay speed [mil/ps] of DDR3 lines (Single : 50 Ohm, Differential : 100 Ohm).

Best Regards,

You may use typical value of ~150 ps / inch for estimations.

Hi Yuri,

Thank you for your reply.

>You may use typical value of ~150 ps / inch for estimations.

Is it i.MX6Q SABRE-AI's data?

If it is no, do you have information of propagation delay speed [mil/ps]?

  I do not have data specific for the Sabre-AI design, sorry.
But hardly results for the Sabre-AI will significantly differ from typical.
