APPLICATION INFORMATION
using the THS1240 clock input (continued)
If the dc component of the input clock differs from VDD/2 by more than 10%, it is best to connect the CLK+ input
to the clock source through a 0.01
F capacitor. In this mode, the converter can operate with a clock having a
peak-to-peak voltage of as little as 2 V with little or no performance degradation (see Figure 9).

The THS1240 clock input can also be driven differentially. If the common mode of the clock input is VDD/2, then
the clock inputs can be driven directly (see Figure 10)

Figure 10. Differential Clock Input
If the clock input is driven differentially with a clock signal having a common mode voltage that is different from
VDD/2, then it is best to connect both clock inputs to the differential input clock signal with 0.01 F capacitors
(see Figure 11). The differential input swing can vary between 2 V and 5 V with little or no performance
degradation.
