Programmable Oscillators Procurement Notes

Verify the exact operating frequency and output configuration required for your specific application before ordering, as the Si591 series offers multiple variants. Confirm that the LVPECL output format aligns with your receiver's input requirements. Ensure the 7x5 mm surface mount package fits within your PCB layout constraints. Check for any specific environmental or compliance certifications needed for your region. Cross-reference the datasheet for detailed electrical characteristics to ensure compatibility with your power supply and load conditions.

Programmable Oscillators Selection Notes

Select this component when a fixed-frequency XO in the 10-810 MHz range is needed with LVPECL outputs. Consider the Si591 series if low phase noise and high stability are critical for your design. Evaluate the 3.3V supply requirement against your system's available voltage rails. The enable/disable feature allows for dynamic power savings in battery-operated devices. Compare against other Skyworks oscillators if different output formats like CMOS or CML are preferred.
