Oscillators Procurement Notes

Verify the specific suffix codes against official Skyworks documentation to ensure correct output format and packaging configuration. Confirm that the required frequency stability and load capacitance specifications align with the target circuit design before procurement. Check current availability status as lead times may vary based on production schedules.

Oscillators Selection Notes

Select this component when a fixed frequency VCXO with LVPECL outputs is required for frequencies up to 945 MHz. Ensure the application environment stays within the specified -40°C to +85°C operational range. Verify that the system power supply can maintain the 2.97 V to 3.63 V input window for reliable operation.

Oscillators Part Context

This part belongs to the Si550 series of VCXOs from Skyworks Solutions. The series provides flexible timing solutions for various communication protocols. The 550SF variant specifically denotes the LVPECL output type and standard packaging, distinguishing it from other output formats or package sizes within the same family.

Oscillators Replacement Considerations

Direct replacements must match the 155.52 MHz frequency, LVPECL output, and 7 mm x 5 mm package dimensions. Verify compatibility with existing control voltages and load capacitance requirements. Cross-reference with other Si550 variants if different output formats are acceptable.
