Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency configuration and pinout compatibility against your schematic before ordering. Confirm that the LVPECL output level matches your receiver input requirements. Ensure the 3.3 V supply rail can handle the 130 mA peak current draw without significant droop. Check lead times as production cycles may vary by region.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this model when a dual-frequency VCXO with LVPECL outputs is required in a compact form factor. Compare against other Si552 variants if CMOS or different voltage levels are needed. Consider the 20 PPM stability requirement against your system's jitter tolerance. Verify that the 10-945 MHz range covers all necessary operational bands for your application.

Pin ConfigurableSelectable Oscillators Part Context

This part belongs to the Skyworks Si552 family of low-jitter oscillators. It shares the same physical package dimensions and general electrical characteristics with other models in the series, such as the 552AJ and 552CK series. The primary differentiator is the specific frequency range and output format defined by the suffix code.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct substitutes include other Skyworks Si552 series parts with matching LVPECL outputs and similar frequency ranges, such as the 552AJ000107DGR or 552ED000132DGR, provided the specific frequency and stability parameters align with the design requirements.
