C
A crystal can be characterized for either series or parallel mode
operation. The ICS85357-11 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 1 . Typical results using parallel 18pF crystals are shown
in Table 7.
