Key electrical specifications include a maximum operating current of 43 mA and a disabled current of 18 mA. Frequency stability options include ±20 ppm and ±30 ppm variants. The component supports surface mount installation and functions within a temperature range of -40°C to +85°C.

Programmable Oscillators Feature Summary

• Programmable frequency generation capability within the 170 MHz to 250 MHz range
• LVPECL differential output format for high-speed signal integrity
• Integrated enable/disable control pin for power management optimization

Programmable Oscillators Applications

• High-speed data communication interfaces requiring precise timing
• Telecommunications equipment clock distribution networks
• Industrial automation systems with strict synchronization requirements

Programmable Oscillators Procurement Notes

Verify the specific frequency order code suffix as the base model indicates a programmable range rather than a fixed value. Confirm the required frequency stability specification (±20 ppm or ±30 ppm) matches the application timeline accuracy needs. Ensure the LVPECL output compatibility aligns with the receiving logic circuit voltage levels. Check the latest datasheet for any revisions affecting the enable pin logic or thermal characteristics before finalizing the design.

Programmable Oscillators Selection Notes

Select this component when a fixed-frequency crystal cannot meet the system's jitter or frequency agility requirements. The Si511 series offers flexibility in frequency selection compared to standard XO devices. Consider the 2.5 V supply constraint against available board power rails. The 6-SMD package size fits dense PCB layouts but requires adequate spacing for thermal dissipation during continuous operation at maximum current draw.

Programmable Oscillators Part Context

This part belongs to the Skyworks Si511 family of standard oscillators, which provides general-purpose clock solutions. Unlike fixed-frequency models, the ECB variant allows for custom frequency programming. It competes with other programmable oscillators in the telecom and networking sectors. The series emphasizes low phase noise and wide frequency coverage, supporting diverse digital system timing architectures across various industrial and commercial applications.

Programmable Oscillators Replacement Considerations

Direct substitutes may include other Skyworks Si511 variants with matching package dimensions and LVPECL outputs. Verify that alternative parts support the same 2.5 V supply voltage and enable pin functionality. Cross-reference the frequency stability requirements to ensure equivalent performance. Note that some replacements might require different programming tools or configuration procedures.
