Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency option required during ordering, as the part number suffix defines the exact output frequency among the quad options. Confirm package compatibility with the 7 mm x 5 mm footprint. Ensure power supply rails remain within the 2.97 V to 3.63 V range to maintain specified electrical characteristics. Check lead times as manufacturing cycles may vary.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when low jitter and quad frequency flexibility are critical. Compare against other Si554 variants based on required output format and stability. Ensure the CML output matches the receiving circuit's input requirements. Consider thermal management within the -40°C to +85°C operating range for the specific application environment.

Pin ConfigurableSelectable Oscillators Part Context

This model belongs to the Si554 family of VCXOs, designed for high-performance clocking needs.
