Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency configuration (850 MHz or 900 MHz) required for your application before ordering, as the part number indicates dual-frequency capability but specific unit delivery may correspond to one setting. Confirm that the LVPECL output format aligns with your receiver's input requirements. Ensure the 2.5 V supply voltage matches your system's power rails. Check the latest datasheet for any updates regarding pinout configurations or environmental specifications.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this VCXO when a low-phase-noise, high-frequency reference is needed in a small form factor. The LVPECL interface is ideal for driving high-speed digital inputs directly. Consider the 2.5 V operating voltage if your system does not support higher voltages like 3.3 V. The enable/disable feature allows for dynamic power savings. Compare against other Si552 series parts if different output formats such as CMOS or LVDS are preferred.

Pin ConfigurableSelectable Oscillators Part Context

This component belongs to the Skyworks Si552 family of VCXOs, known for high performance and flexibility. The 552EJ000359DGR specifically targets high-frequency applications with its 850/900 MHz range. It shares the same 6-SMD package footprint with other variants in the series, facilitating board layout standardization across different frequency and output type selections within the same product line.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct substitutes within the Si552 series include 552EC001125DGR, 552AD000593DGR, 552BM000598DGR, 552CK000353DGR, and 552BG000537DGR. Note that these alternatives may differ in operating voltage (e.g., 3.3 V), output format (CMOS/LVDS), or specific frequency ranges. Verify electrical compatibility and pinout equivalence before substitution.
