I am in a middle of layout stage with your items HX2 and
I am using the HX3 - CYUSB3314.
I have long trace length constrain - 4 inch for
USB2: DS3_D (pins 77 and 78) on the CYUSB3314.
When reading cypress HX3 HW design guide (AN91378)
, page16, I can see information regarding the SS lines - up to 11inch’s,length, which is great.
But no info regarding the USB2 signal length.
Could you please advise, What is the maximum allowed , trace length for USB2, with the HX3 - CYUSB3314, and especially on this specific
pins (77, 78) driver ?
