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 ratio

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