Oscillators Procurement Notes

Verify the complete part number including suffixes to ensure correct voltage, output type, and pull range specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for your assembly process. Check for any recent PCN notifications regarding material changes or manufacturing location updates before finalizing procurement orders.

Oscillators Selection Notes

Select this model when low jitter and high linearity are critical for system timing integrity. The Elite Platform offers superior phase noise compared to standard quartz devices. Ensure the required pull range and stability meet application needs, as these parameters are factory-programmed and cannot be adjusted post-production. Consider the integrated power regulation benefits for simplified board design.

Oscillators Part Context

This component belongs to the SiT3372 series, which provides ultra-low jitter differential VCXOs ranging from 1 MHz to 220 MHz. The Elite Platform distinguishes itself by maintaining exceptional dynamic performance under environmental stress. The series supports various output types including LVPECL, LVDS, and HCSL, offering flexibility for diverse interface requirements in modern electronic designs.

Oscillators Replacement Considerations

Direct substitutes within the same family include SIT3372AC-1E2-30NU76.800000 for different frequency and stability configurations. Other variants like SIT3372AI support different voltage levels such as 2.5V or 3.3V.
