Hello All,
We are using Atom E38XX on one of our product, we need USB mass storage device / Pen drive should work with 3 to 4 mtr cable length. ( we need at least one or two port)
As of now its working fine on only one port (USB_DP3 & USB_DN3), remaining (3+2) ports are not working beyond 1 mtr cable. Low speed devices are working fine on all ports with 5 mtr cable.
We have taken care of PCB trace length & its diff pair matching, Common mode, ESD, Shielded cables... . We have added USB2 Data Switch (TS3USB221A-Q1) on two USB path (one port where USB mass storage is working with 5 mtr also has this USB2 data sheet)
Kindly request you all to provide your valuable suggestions / Feedback
Thanks in-advance.
