Programmable Oscillators Procurement Notes

Verify the specific target frequency required for your application during the ordering process, as this model is a programmable oscillator. Confirm that the CMOS output type and 2.5V supply voltage align with your system design constraints. Ensure the 7x5mm package dimensions fit your PCB layout requirements before finalizing procurement.

Programmable Oscillators Selection Notes

Select this component when a flexible, programmable clock source is needed rather than a fixed-frequency alternative. Consider the ±25 ppm stability requirement against your system's jitter tolerance. Verify that the 2.5V operating voltage matches your available power rails, as other variants in the series may support different voltages like 1.8V or 3.3V.

Programmable Oscillators Part Context

This part belongs to the Si511 family of programmable oscillators manufactured by Skyworks Solutions. These devices are engineered to replace multiple fixed-frequency crystals and oscillators, reducing inventory complexity. The Si511 series is widely used in applications requiring precise timing with minimal board space and low power consumption.

Programmable Oscillators Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the 511QBA-ABAG and 511QCA-ABAG models. When replacing, ensure the output format (CMOS), supply voltage (2.5V), and package size remain compatible with the existing design.
