Procurement Notes

Verify the specific frequency configuration required by your design, as this part supports dual frequencies such as 148.351648 MHz and 148.5 MHz. Confirm that the LVPECL output format matches your receiver inputs. Ensure the 7 mm x 5 mm SMD footprint aligns with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when differential LVPECL signaling is required for noise immunity in high-speed data paths. The Si512 series offers flexibility through pin-configurable options. Consider the 20 PPM stability requirement against your system's jitter tolerance. Verify power supply compatibility with the 3.3 V nominal specification and ensure thermal management suits the -40°C to +85°C operating range.

Part Context

This oscillator belongs to the Si512 family of pin-programmable devices from Skyworks Solutions. These components are engineered for general-purpose clocking needs where multiple frequency options or configurable outputs reduce bill-of-materials complexity. The series emphasizes small form factors and robust performance across industrial temperature ranges.

Replacement Considerations

Cross-reference with other Si512 variants if different frequency pairs or output formats like CMOS/LVDS are needed. Verify package dimensions remain compatible. Check datasheets for specific ordering suffixes that define exact frequency selections and enable pin logic.
