faces suggested here are examples only. Please consult with
the vendor of the driver component to confirm the driver termi-
nation requirements. For example in Figure 2A, the input ter-
mination applies for ICS HiPerClockS LVHSTL drivers. If you
are using an LVHSTL driver from another vendor, use their
termination recommendation.
