Hi,
=20
we use an ICH4 in our design and try to verify the transfer speed of
480Mbps for USB 2.0.=20
I already used a USB 2.0 CD-writer (although, that wont even fully use
12Mbps for USB 1.1) and most recent, I tried the 10/100Mbps USB 2.0 to
Ethernet adapter from Linksys. I both cases, I can clearly see the 80ns
eye width for the USB 1.1 speed.
How can I test and verify the eye diagram for USB 2.0 and what
peripheral can I use for testing it?
=20
Any help appreciated !
=20
Thanks,
=20
Ingo
