Description

The Si510/511 XO utilizes Silicon Laboratories' 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 Silicon Labs’ 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.
