Programmable Oscillators Procurement Notes

Verify the specific part number suffix against official Skyworks documentation to confirm electrical characteristics, as variations may exist between standard and programmable variants. Ensure that the required frequency and output format match the design specifications before procurement. Cross-reference the datasheet for pinout compatibility and thermal requirements to prevent integration issues during assembly.

Programmable Oscillators Selection Notes

Select this component when a programmable LVDS clock source is required for 156.25 MHz applications. Consider the 7 ppm stability requirement and the 2.5 V operating voltage. Evaluate the 7x5 mm footprint against available board space. Compare against other Si590 variants if different output formats or voltage levels are needed for the target system architecture.

Programmable Oscillators Part Context

The 590FD-BDG belongs to the Si590 family of single-frequency general-purpose oscillators. This series offers various output formats including LVDS, LVPECL, and CMOS across a wide frequency range. The programmable nature distinguishes it from fixed-frequency counterparts, providing design flexibility for custom clock generation needs in complex electronic systems.

Programmable Oscillators Replacement Considerations

Direct replacements within the Si590 series include models with identical 156.25 MHz frequency and LVDS output, such as 590FD74M2500DGR if frequency tolerance permits, or other programmable variants like 590BD296M704DGR for different frequencies. Verify pin-to-pin compatibility and voltage requirements before substitution.
