Oscillators Procurement Notes

Verify the exact part number against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required output type and package variant. Confirm that the specified frequency and stability requirements align with the system design constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a differential VCXO with LVDS outputs is required for frequencies between 220 MHz and 725 MHz. Consider this part for designs needing immunity to environmental stressors like vibration and thermal shifts. It is suitable for applications where eliminating external filtering components via integrated on-chip regulators simplifies the PCB layout.

Oscillators Part Context

This model belongs to the SiT3373 Elite Platform series, which covers a wide frequency range from 220 MHz to 725 MHz. The series is designed to replace quartz oscillators by offering programmability and superior dynamic performance. It targets markets demanding high reliability and precise clock generation in challenging operational conditions.

Oscillators Replacement Considerations

Direct substitution requires verifying that the replacement part supports the same 644.53125 MHz frequency, LVDS output format, and 3.3V operation. Check if the alternative component meets the -20°C to 70°C temperature range and ±15 ppm stability requirements. Ensure mechanical footprint compatibility for the 7.00mm x 5.00mm package.
