For applications not requiring the use of the crystal oscillator input,
both XTAL_IN and XTAL_OUT can be left floating. Though not
required, but for additional protection, a 1k
from XTAL_IN to ground.
CLK I
For applications not requiring the use of a clock input, it can be
left floating. Though not required, but for additional protection, a

LVCMOS C
All control pins have internal pull-ups or pull-downs; additional
resistance is not required but can be added for additional
protection. A 1k

The ICS8534I-13 has been characterized with 18pF parallel
resonant crystals. The capacitor values, C1 and C2, shown in
Figure 2 below were determined using an 18pF parallel resonant
crystal and were chosen to minimize the ppm error. These same

All unused LVCMOS output can be left floating. We recommend
that there is no trace attached.
LVPECL O
The unused LVPECL output can be left floating. We recommend
that there is no trace attached. Both sides of the differential output
pair should either be left floating or terminated.
capacitor values will tune any 18pF parallel resonant crystal
over the frequency range and other parameters specified in
this data sheet. The optimum C1 and C2 values can be slightly
adjusted for different board layouts.
