INPUT INTERFACING
The DS15BR400 and DS15BR401 accept differential signals and allow simple AC or DC coupling. With a wide common mode
range, the DS15BR400 and DS15BR401 can be DC-coupled with all common differential drivers (i.e. LVPECL, LVDS, CML). The
following three figures illustrate typical DC-coupled interface to common differential drivers. Note that the DS15BR400 inputs are
internally terminated with a 100Ω resistor while the DS15BR401 inputs are not, therefore the latter requires external input termi-
nation.
