Description
The Si514 user-programmable I
2
C XO utilizes Silicon Laboratories' advanced PLL
technology to provide any frequency from 100 kHz to 250 MHz with programming
resolution of 0.026 parts per billion. The Si514 uses a single integrated crystal and
Silicon Labs’ proprietary DSPLL synthesizer to generate any frequency across this
range using simple I
2
C commands. Ultra-fine tuning resolution replaces DACs and
VCXOs with an all-digital PLL solution that improves performance where
synchronization is necessary or in free-running reference clock applications. 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 Si514 is factory-configurable for a wide variety of user specifications, including
startup frequency, I
2
C address, supply voltage, output format, 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.
