November 21, 2002 Document No. 001-43117 Rev. ** 2 AN1196 Figure 2. FX2 Eye Diagram of High-speed Signaling In the diagram, notice how no signal traces overlap the cen-tral, six-sided, shaded area. Also, no trace overlaps theextremes of permissible voltage as shown in the shaded linesat the very top...

Page 3 - Maintain PCB Trace Impedance; Table 3; Zdiff; Figure 3; Z d i f f

November 21, 2002 Document No. 001-43117 Rev. ** 3 AN1196 Maintain PCB Trace Impedance Designing the PCB traces for particular characteristic imped-ance is very important to signal quality. The USB specificationrequires controlled impedance among all elements in theUSB data path. The differential im...

November 21, 2002 Document No. 001-43117 Rev. ** 4 AN1196 This figure shows the dielectric material thickness (“Prepreg”)between layers 1 and 2 and the thickness between layers 3and 4. The dimensions between these layers are a key ele-ment in the design to set the proper characteristic impedancefor ...
