DS250DF230: PRBS generator and mission mode usage

Liang Qiao

Part Number: DS250DF230


Hi,

On page 33 of SNLU182H (the programmer's guide for DS2x0DF810, DS250DFx10, DS250DF230), there is a note stating that the PRBS generator is a test feature and is not intended for mission mode usage. What does it mean by "mission mode usage"? Would this mean using the PRBS functionality as the main feature of a product and is not rated to be turned on and off repeatedly?

If I were to stick to the recommendation of not enabling more than 2 generators/checkers per quad, am I able to run them for 600 (ideally 920) seconds at a time if I have incorporated good thermal design?

Regards,

Liang

    Hi Liang, 

    I will check on this internally and get back to you as soon as possible.

    Hi Liang,

    The note in the Programming Guide that you are referring to is stating that the PRBS generator works, but has a limited channel count. In addition, device validation focuses on the typical use case (retimer) and has less emphasis on the PRBS generator.  If you follow these recommendations for PRBS generator/checker use and incorporate good thermal design, these run times should not be an issue.

    Best regards,

    Greg
