faces suggested here are examples only. Please consult
with the vendor of the driver component to confirm the driver
termination requirements. For example in Figure 4A, the
input termination applies for HSTL drivers. If you are using
an LVHSTL driver from another vendor, use their termina-
tion recommendation.
