7.3.2 Linear Equalization

With a linear equalizer, the TUSB1002 can electrically shorten a particular channel allowing for longer run lengths.

TUSB1002 llinear_equaliz_sllseu4.pngFigure 16. Linear Equalizer

With a TUSB1002, the 28 in trace can be made to have similar insertion loss as the 12 inch trace.

The receiver equalization level for each channel is determined by the state of the CHx_EQ1 and CHx_EQ2 pins, where x = 1 or 2.
