DIFFERENTIAL-TO-LVPECL MULTIPLEXER

APPLICATION INFORMATION

FIGURE 1A. SINGLE ENDED LVCMOS SIGNAL DRIVING DIFFERENTIAL INPUT

Figure 1A shows an example of the differential input that

can be wired to accept single ended LVCMOS levels. The

reference voltage level V

BB generated from the device is

WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LVCMOS LEVELS

connected to the negative input. The C1 capacitor should

be located as close as possible to the input pin.

FIGURE 1B. SINGLE ENDED LVPECL SIGNAL DRIVING DIFFERENTIAL INPUT

Figure 1B shows an example of the differential input that

can be wired to accept single ended LVPECL levels. The

reference voltage level V

BB generated from the device is

connected to the negative input.
