Folks,
I'm designing a usb2.0 related things which require a connection between motherboard(host) and custom usb2.0 device. There's one document form intel called " Front panel I/O design guide". This document suggest to use normal 100 mil header for the internal connection for the usb. I'm just wondering whether the normal 100 mil header can meet the 90 ohm diferential impedance which require by the USB spec. I couldn't seem to find this dat. Anyone has any info. about this?
Thanks,
KJ.
