7.3.2 Linear Equalization

With a linear equalizer, the TUSB1002A can electrically shorten a particular channel allowing for longer run lengths.

GUID-1F2B848F-E70A-4DA9-9E06-0A609BB25EF9-low.gif Figure 7-1 Linear Equalizer

With a TUSB1002A, a longer trace can be made to have similar insertion loss as a shorter trace. For example, a long trace of X + Y inches can be made to have similar loss characteristics of a shorter trace of X inches.

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.
