It maintains a frequency stability of 50 PPM and supports operation across an industrial temperature range of -40°C to +85°C.

Programmable Oscillators Feature Summary

• Programmable frequency generation capability covering a wide operational bandwidth
• Integrated enable and disable control functionality for power management

Programmable Oscillators Applications

• General-purpose clock signal distribution in electronic systems
• High-speed data transmission interface timing references
• Telecommunications equipment requiring stable programmable clocks

Programmable Oscillators Procurement Notes

Verify that the specific part number suffix matches the required programming configuration, as programmable oscillators often require distinct firmware or initialization sequences. Confirm compatibility with the target system's voltage levels and output load requirements before procurement. Ensure that the supplier provides valid documentation regarding the programming process and any necessary software tools for setting the desired frequency parameters.

Programmable Oscillators Selection Notes

Select this component when a flexible, single-frequency output is required within the specified high-frequency range. Consider the CML output format for compatibility with differential input receivers. Evaluate the 50 PPM stability against system jitter requirements. The 3.3 V operating voltage makes it suitable for standard logic families, while the enable pin allows for dynamic power state control in battery-operated or energy-efficient designs.

Programmable Oscillators Part Context

This model belongs to the Si591 family of standard clock oscillators manufactured by Skyworks Solutions. The series is characterized by its programmability and compact form factor, catering to modern electronics that demand precise timing signals in minimal space. It serves as a direct replacement for fixed-frequency oscillators where design flexibility is prioritized over static clock sources.

Programmable Oscillators Replacement Considerations

Direct substitutes may include other Skyworks Si591 variants with different fixed frequencies or output formats. Cross-reference with similar programmable oscillators from competitors if specific programming constraints are not met. Verify pinout compatibility and thermal characteristics when substituting with non-programmable alternatives.
