C
A crystal can be characterized for either series or parallel mode
operation. The ICS83908-02 has a built-in crystal oscillator
circuit. This interface can accept either a series or parallel
crystal without additional components and generate fre-
I
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 resister 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 resister can be tied from the CLK input to ground.
S
All select pins have internal pull-ups and pull-downs; additional
resistance is not required but can be added for additional
protection. A 1k resister can be used.

accuracy can be achieved by adding two small capacitors C1
and C2 as shown in Figure 1 . Typical results using parallel 18pF
crystals are shown in Table 5.
