Unlike a traditional XO, where a different crystal is required for each output frequency, Silicon Labs’ XO/VCXOs use a fixed frequency crystal and DSPLL clock synthesis IC to generate any output frequency. This IC-based approach delivers exceptional frequency stability and reliability, while providing best-in-class jitter performance and supply noise rejection, simplifying the task of generating low-jitter clocks in noisy environments. All devices are factory configurable for a wide variety of user specifications, including frequency, supply voltage, output format and stability, thereby eliminating long lead times associated with custom oscillators.
