APPLICATIONS INFORMATION

Figure 48 to Figure 50 illustrate the common input interface

configurations. Figure 48 shows how to interface a LVCMOS

input to the HMC6832. A capacitor is needed between the

LVCMOS driver and the HMC6832 to ac couple the input. In

addition, add a capacitor between the inverted input of the

HMC6832 and a nearby GND pin to reduce noise in the system.
