Description

The Si514 user-programmable I

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

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

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.
