ICS85320I
LVCMOS/LVTTL-TO-DIFFERENTIAL 3.3V, 2.5V LVPECL TRANSLATOR
APPLICATION SCHEMATIC EXAMPLE
Figure 3 shows an example of ICS85320I application schematic.
In this example, the device is operated at V =3.3V.The decoupling
CC
capacitor should be located as close as possible to the power
pin. For LVPECL output termination, only two terminations
examples are shown in this schematic. For more termination
approaches, please refer to the LVPECL Termination Application
