Simplified external crystal/ceramic oscillator circuits are shown in Figure 6.3.1.1. An external crystal or

ceramic oscillation source provides 355KHz~8MHz. The load capacitor Cx which values used in the oscillator

circuit design should include all stray capacitance is necessary, but frequency is more than 3.5MHz, Cx can be

removed. The crystal and components should be mounted as close as possible to the pins for start-up

stabilization and to minimize output distortion.

Using 455KHz crystal/ceramic oscillation is shown Figure 6.3.2.1，generally OSCI/OSCO must be

connected external 200pF capacitor. Otherwise OSCO can be connected 2KΩ to 5KΩ resistor that can be

used by carbon film resistor.
