Multi−Channel Deskewing
channel delay matching. Slight differences in impedance
and cable length can create large timing skews within a
high−speed system. To deskew multiple signal channels,
each channel can be sent through each EP196 as shown in
The most practical application for EP196 is in multiple

Figure 8. One signal channel can be used as reference and the
other EP196s can be used to adjust the delay to eliminate the
timing skews. Nearly any high−speed system can be fine
tuned (as small as 10 ps) to reduce the skew to extremely
tight tolerances using the available FTUNE pin.
