examples only. Please consult with the vendor of the driver
component to confirm the driver termination requirements. For
example in Figure 3A, the input termination applies for ICS
HiPerClockS LVHSTL drivers. If you are using an LVHSTL driver
from another vendor, use their termination recommendation.
