Hi,
Please let me confirm the following question.
[Question]
Do you have the USB timing chart for AM335x?
I checked the datasheet of AM335x, however we could not find out it.
If you have any question, please let me know.
Best regards.

Hi Kato,
AM335X USB timings conform to the USB 2.0 specification.
There is no such data for AM335X, that's why I refer you to the USB 2.0 specification. All electrical parameters are listed in Chapter 7 of the USB 2.0 specification.
I don't have information on this. You can contact your nearest TI representative and request additional information.
Hello Kaka-san
The data you show in the DM8148 datasheet (you will also see the same table in OMAPL-L138 datasheet) is a distilled version of the information from the USB org standards specification.
On AM335x, we decided that there is no point replicating/duplicating the information as you can essentially get the same information from the standard specs for the limits and margins.
Going forward, you will see us follow the AM335x data-sheet approach for new device datasheets. Only if there are deviations from the USB industry specification, we will call out explicitly in our collateral.
Hope this helps.

Hi Mukul,
Thank you for you response.
To summarize your answer, we should follow the USB.org specification in basically. And if there are deviations, you will point out them.
Is my understanding correct?
I think personally that you should define those specifications for this device by device provider like DM8148 datasheet even though you think.
Best regards.
