Product Information

The Si514 user-programmable I²C 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 I²C 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 start-up frequency, I²C 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.

Applications:
• All-digital PLLs
• DAC+ VCXO replacement
• SONET/SDH/OTN
• 3G-SDI/HD-SDI/SDI
• Datacom
• Industrial automation
• FPGA/ASIC clock generation
• FPGA synchronization
