APPLICATION INFORMATION

WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LEVELS

Figure 1 shows how the differential input can be wired to accept of R1 and R2 might need to be adjusted to position the V_REF in

single ended levels. The reference voltage V_REF = V /2 is

DD

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 VDD = 3.3V, V_REF should be 1.25V

and R2/R1 = 0.609.
