Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable 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 =20 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D =3D Ingo Kupper =3D =3D Sr. Electronics Engineer =3D =3D +1(510)732-6900 x159 =3D =3D ingo.kupper@xxxxxxxxxxx <outbind://15/ingo.kupper@xxxxxxxxxxx> = =3D =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D =3D Kontron America =3D =3D 3988 Trust Way =3D =3D Hayward, CA 94545 =3D =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D -- Binary/unsupported file stripped by Ecartis -- -- Type: image/jpeg -- File: Notebook.jpg -- Desc: Notebook.jpg ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
