SILICON LABS 515CDA25M0000AAG

The Si515 VCXO utilizes Skyworks Solutions' advanced PLL technology to provide any frequency from 100 kHz to 250 MHz. Unlike a traditional VCXO where a different crystal is required for each output frequency, the Si515 uses one fixed crystal and Skyworks Solutions’ proprietary 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 control voltage linearity and supply noise rejection, improving PLL stability and simplifying low jitter PLL design in noisy environments. The Si515 is factory-configurable for a wide variety of user specifications, including frequency, supply voltage, output format, tuning slope 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.
