Figure 7 shows an example of ICS853031 application schematic.

In this example, the device is operated at V

decoupling capacitor should be located as close as possible to

the power pin. The input is driven by a 3.3V LVPECL driver. Only

two terminations examples are shown in this schematic. For

more termination approaches, please refer to the LVPECL Ter-

mination Application Note.
