C
The ICS8536-02 has been characterized with 18pF paral-
lel resonant crystals. The capacitor values shown in Figure

C
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
resistor can be tied from XTAL_IN to ground.
CLK I
For applications not requiring the use of the test clock, it can
be left floating. Though not required, but for additional
protection, a 1k
ground.
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

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
