FPGA/ASIC clock generation
Description
The Si510/511 XO utilizes Skyworks Solutions' advanced DSPLL technology
to provide any frequency from 100 kHz to 250 MHz. Unlike a traditional XO
where a different crystal is required for each output frequency, the Si510/511
uses one fixed crystal and Skyworks Solutions’ proprietary DSPLL
synthesizer to generate any frequency across this range. This IC-based
approach allows the crystal resonator to provide enhanced reliability,
improved mechanical robustness, and excellent stability. In addition, this
solution provides superior supply noise rejection, simplifying low jitter clock
generation in noisy environments. Crystal ESR and DLD are individually
production-tested to guarantee performance and enhance reliability. The
Si510/511 is factory-configurable for a wide variety of user specifications,
including frequency, supply voltage, output format, output enable polarity,
and stability. Specific configurations are factory-programmed at time of
shipment, eliminating long lead times and non-recurring engineering charges
associated with custom frequency oscillators.
