Wiring the Differential Input to Accept Single-Ended Levels
Figure 1 shows how the differential input can be wired to accept
single-ended levels. The reference voltage V_REF = VCC/2 is
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 of
R1 and R2 might need to be adjusted to position the V_REF in the
center of the input voltage swing. For example, if the input clock
swing is only 2.5V and VCC = 3.3V, V_REF should be 1.25V and
R2/R1 = 0.609.
