Crystal Parameters Recommendation for Cypress Frequency Synthesizers
A PLL-based frequency synthesizer uses a reference input to generate output clocks. The reference can be provided by a quartz crystal or an external clock source. The accuracy and stability of the output clock is directly proportional to that of the reference. Thus, it is important to provide a stable, accurate, and appropriate reference input.
