Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required electrical parameters, including the 2.8V supply, LVDS output format, and ±50ppm stability. Confirm the package type is 6-SMD No Lead Exposed Pad and ensure the temperature grade corresponds to the AC variant (-40 to +85C). Cross-reference the part number against official SiTime documentation to confirm availability and manufacturing status before procurement.

Oscillators Selection Notes

Select this component when a differential VCXO with integrated power regulation is required for robust performance in electrically noisy environments. The choice is driven by the need for factory-programmable flexibility without custom quartz lead times. Ensure the design supports the 2.8V supply rail and accommodates the 7x5mm footprint constraints while requiring LVDS interface compatibility.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series, which offers ultra-low jitter differential MEMS oscillators ranging from 1 MHz to 220 MHz. The platform is designed to replace traditional quartz devices by providing programmability and superior dynamic stability against environmental stressors like airflow and vibration through proprietary silicon-based compensation technologies.

Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source data. Verify compatibility with existing designs by matching the 50 MHz frequency, LVDS output, 2.8V supply, and 6-SMD package dimensions against alternative MEMS VCXOs if substitution is necessary.
