PRELIMINARY

An application schematic example of ICS854058 is shown

in

Figure 4. The inputs can accept various types of differential

signals. In this example, the inputs are driven by LVDS drivers.

The transmission lines are assumed to be 100

Ω differential.

The 100

Ω matched loads termination should be located

near the receivers. It is recommended at least one

decoupling capacitor per power pin. The decoupling ca-

pacitor should be low ESR and located as close as pos-

sible to the power pin.
