Figure 2 shows an example of ICS83905I application schematic.
In this example, the device is operated at V
= 3.3V and V
=
3.3V. The decoupling capacitors should be located as close as
possible to the power pins. The input is driven by an 18pF load
resonant quartz crystal. The tuning capacitors (C1, C2) are fairly
accurate, but minor adjustments might be required. For the
LVCMOS output drivers, two termination examples are shown
in the schematic. For additional termination, examples are shown
in the LVCMOS Termination Application Note.
