Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency option required, as the part number suffix indicates one of four supported frequencies: 155.52 MHz, 161.13281 MHz, 167.33165 MHz, or 173.37075 MHz. Confirm the LVPECL output requirement matches the system design. Ensure the 2.5 V supply voltage aligns with the target application power rails. Check the manufacturing lead time, which is approximately 20 weeks, for production planning purposes.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when a fixed-frequency, low-jitter source is needed for high-speed links requiring LVPECL signaling. The Si534 series offers superior jitter performance compared to standard crystal oscillators. Consider the 7x5mm package size for board space constraints. This part is suitable for applications where frequency agility is not required, but precise timing and low phase noise are critical for signal integrity.

Pin ConfigurableSelectable Oscillators Part Context

The 534EC000129DGR belongs to the Si534 family of quad frequency low jitter oscillators. These devices are engineered to replace discrete crystal and buffer solutions, providing a compact alternative for demanding clocking applications. The series is characterized by its ability to support common data rate frequencies while maintaining tight stability and low jitter specifications across industrial temperature ranges.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct substitutes may include other Skyworks Si534 variants with different frequency options or output formats. Cross-reference with Si534xx part numbers to match the specific frequency and LVPECL output requirements. Verify package dimensions and pinout compatibility before substitution.
