CRYSTAL INPUT INTERFACE
A crystal can be characterized for either series or parallel mode
operation. The ICS84329B-01 has a built-in crystal oscillator
circuit.This interface can accept either a series or parallel crystal
without additional components and generate frequencies with
accuracy suitable for most applications. Additional accuracy can
be achieved by adding two small capacitors C1 and C2 as shown
in Figure 5.
