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