hello.
Our board has a processor and a TUSB8042A, which is connected to the upstream side of the TUSB8042A via a USB 2.0 interface.
However, in the case of on-board connections, the EYE mask rule of the USB 2.0 standard does not apply.
Please tell me the following points.
【question 1】
There was no input specification for USB2.0 of TUSB8042A (DEVICE) on the UPSTREAM side in the datasheet.
What are the USB2.0 input specifications for TUSB8042A (DEVICE) on the UPSTREAM side?
Please let me know if there are any regulations such as VID.
[Question 2]
When I checked the USB specification document 2.0, the following EYEMASK regulations were described.
In the case of on-board connection, is there no problem as long as the following TP4 EYEMASK regulations are met?
