Architecture
Crystal Usage
As an alternative to using an external oscillator, a fundamental 27 MHz crystal may be
connected between EXTCLK and XTAL. Two small loading capacitors of 10–22 pF of NPO
dielectric should be added as shown in Figure 3.
ON Semiconductor does not recommend using the crystal option for applications above
85°C. A crystal oscillator with temperature compensation is recommended.

Note: Value of load capacitor is crystal dependent. Crystal with small load capacitor is recommended.
