PRODUCTION DATA
6.3.2 Linear Equalization
With a linear equalizer, the SN75LVPE3101 can electrically shorten a particular channel allowing for longer run lengths.
Figure 6-1 Linear
EqualizerWith a SN75LVPE3101, 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.
