Programmable Oscillators Procurement Notes

Verify the specific output frequency required during ordering, as this model is programmable. Confirm that the 1.8V supply voltage aligns with your system design. Ensure compatibility with CML load requirements. Check for any specific programming instructions or tools provided by Skyworks Solutions for frequency configuration before integration into the final product assembly.

Programmable Oscillators Selection Notes

Select the 591WD-BDG when low phase noise and high stability are critical. The CML output suits low-voltage logic families. Compare against LVDS or LVPECL variants if higher drive strength or different voltage levels are needed. Consider the ±7ppm stability requirement against environmental temperature variations. Evaluate the 1.8V supply constraint against available power rails in the target application circuit.

Programmable Oscillators Part Context

This component belongs to the Si591 family of programmable oscillators from Skyworks Solutions. These devices are engineered to replace multiple fixed-frequency crystals and oscillators, reducing inventory complexity. The 591WD series specifically targets applications requiring CML outputs and tight jitter performance. It complements other Skyworks timing solutions like the 591SC and 591AA series, which offer different output formats and voltage levels.

Programmable Oscillators Replacement Considerations

Direct substitutes may include other Skyworks Si591 models with compatible output formats such as LVDS or LVPECL, depending on the interface requirements. Verify pin-to-pin compatibility and electrical specifications before substitution. Generic replacement parts must match the 1.8V supply and CML output characteristics.
