Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required supply voltage, output type, and frequency specifications. Confirm that the 6-SMD exposed pad package matches the target PCB footprint. Check RoHS compliance status and manufacturing date codes for quality assurance. Ensure the selected variant aligns with the intended application's thermal and electrical requirements.

Oscillators Selection Notes

Select this model when a fixed 622.08 MHz VCXO with LVPECL outputs is required. Consider the ±35 ppm stability and ±60 ppm pull range against system jitter budgets. Evaluate the 2.8V supply constraint and 7x5mm package size against board space limitations. Compare against other SiT3373 variants if different frequencies or output formats are needed.
