Applications Information
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 = 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 of
R1 and R2 might need to be adjusted to postion the V_REF in the center of the input voltage swing. For example, if the input clock
swing is only 2.5V and V
