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

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

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 ICS8536I-33 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

All unused LVCMOS output can be left floating. There should be
no trace attached.
LVPECL O
All unused LVPECL outputs 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.
same capacitor values will tune any 18pF parallel resonant
crystal over the frequency range and other parameters speci-
fied in this data sheet. The optimum C1 and C2 values can be
slightly adjusted for different board layouts.
