Dear TI,

As we are using AM6442BSDGHAALV (USB2.0 480Mbps) in one of our designs and we wanted to know the EYE Mask Specification/data for AM6442BSDGHAALV to conclude on the SI simulation.

Thank you.

Hi Amarnath G,

Kindly refer to this forum thread: AM6412: Eye Mask Details required.

I hope this will answer your query.

Hi Stainslav,

Thanks for your response.

When we referred to the thread mentioned above we were not able to find any Specification in terms of Eye-Mask Data/Values. And more over the thread which you have mentioned refers to AM6412 and we would need the data for AM6442.

Request you to provide your thoughts on the same.

Regards
Amarnath G

Amaranth G,

Sorry I had to add some more explanations.

Most important to tell is that TI are not providing such document. Eye masks are defined in the USB2 spec and all USB devices must be compliant. Please see this answer from that thread:

Eye masks are defined in the relevant specifications (USB2, USB3, PCIe). We test our SoC + board to ensure that we comply with these masks. The resulting eye diagrams include the mask, but are board-specific. These aren’t an input for any board design process I’m aware of.

No difference between the two for USB.
