Programmable Oscillators Procurement Notes

Verify the specific programming requirements and final frequency configuration before ordering, as this is a programmable device. Confirm that the LVPECL output format aligns with the target circuit design. Ensure the 2.5 V supply voltage matches the system power rails. Check the lead time for programmed units, as they may require fabrication time after order placement. Validate the 7x5 mm package dimensions against the PCB footprint.

Programmable Oscillators Selection Notes

Select this model when a flexible, programmable clock source is required rather than a fixed-frequency alternative. Consider the LVPECL output if the downstream components support differential signaling. Evaluate the 10-810 MHz range to ensure it covers the necessary operational frequencies. Compare power consumption and stability specifications against other Si591 variants if multiple options exist.

Programmable Oscillators Part Context

This component is part of the Si591 family of standard oscillators from Skyworks Solutions. The family offers various output formats and voltage levels. The 591EC-CDG specifically denotes the LVPECL output variant with 2.5 V operation. It shares the same physical footprint as other models in the series, facilitating design flexibility.

Programmable Oscillators Replacement Considerations

Direct substitutes include other Si591 models with compatible output formats and voltages, such as the 591EC series parts with different frequencies. Verify that any replacement maintains the LVPECL output and 2.5 V supply requirements. Cross-reference the frequency range and stability specifications to ensure functional equivalence.
