Angela,

I don't know where you could get design files, but the following
documents provide design information

1.  IPC-2141 "Controlled Impedance Circuit Boards and High Speed
Logic Design"

2.  "An Introduction to the Manufacture of Controlled Impedance
P.C.B.'s"  available free from

Polar Instruments
5373 Guide Meridian, Building D,
Bellingham, WA 98226

Phone: (360) 398-1946
or  (800) 328-0817

Actual design info is limited to about 1 page, so if you contact me
off-list, I could fax you the details.

Regards
John Parsons
