Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific output format and pin configuration against the official datasheet before procurement, as the Si552 series allows for configurable options. Confirm that the 2.5V supply requirement aligns with your system's power rails. Ensure the 6-SMD package dimensions fit your PCB layout constraints. Cross-reference the part number suffix to guarantee the correct factory preset parameters.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this model when a dual-frequency VCXO with wide bandwidth is required in a compact form factor. The 7x5 mm package suits space-constrained designs. Consider the 117mA current draw for power budgeting. Verify if the ±100 ppm stability meets your phase noise and jitter requirements compared to higher-stability alternatives in the Si552 family.

Pin ConfigurableSelectable Oscillators Part Context

This component belongs to the Skyworks Si552 family of pin-configurable oscillators. These devices are designed to replace multiple discrete oscillator types by offering programmable frequencies and output formats. The 552HA variant specifically targets applications needing dual-frequency operation within a standard surface-mount footprint.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct substitutes within the same family include other Si552 variants with matching package and voltage specifications. Check for differences in output format (LVPECL vs LVDS) and frequency presets. Ensure thermal characteristics and stability metrics remain compatible with the original design intent.
