RMT process

EKabi — Thu, 16 Nov 2017 23:39:58 GMT

Hi,

When RMT is data taken, wondering it's margining only one bit at a time OR multiple bits are margined simultaneously.

I would like to understand the sources of x-talk. Are only the nibble members are x-talk sources OR the byte members or only the associated strobe is the x-talk source?

Thanks,

Ehsan

Hi Carlos,

It's developed by Intel. It does read, write DDR margining for voltage and timing axis.

Hi Carlos,

I am not talking about any technical problem here. Doc # I shared is for the purpose of letting you know what I mean by RMT.

I just asked a question about how RMT works; please see my original post.

Thanks,

Ehsan
