Figure 2 shows how the differential input can be wired to accept
single ended levels. The reference voltage V_REF ~ V
generated by the bias resistors R1, R2 and C1. This bias circuit
should be located as close as possible to the input pin. The

V_REF in the center of the input voltage swing. For example, if
the input clock swing is only 2.5V and V
be 1.25V and R2/R1 = 0.609.
