Oscillators Procurement Notes

Verify the exact ordering suffix against the manufacturer's official datasheet to ensure correct output format and voltage specifications. Confirm that the HCSL output type matches the receiving circuit requirements. Check for RoHS compliance status and lead-free soldering compatibility during procurement validation.

Oscillators Selection Notes

Select this component when a differential VCXO with HCSL outputs is required for 75 MHz applications. Ensure the design accommodates the 3.3V supply voltage and 97mA maximum current draw. Consider the 6-SMD package dimensions for PCB layout constraints and verify that the ±25 ppm stability meets system timing requirements.

Oscillators Part Context

This part belongs to the SiT3372 Elite Platform series, designed for ultra-low jitter differential MEMS VCXO applications ranging from 1 MHz to 220 MHz. The platform emphasizes programmability to replace custom quartz solutions, reducing lead times and customization costs while maintaining high performance in demanding environments.

Oscillators Replacement Considerations

Direct replacement requires matching the 75 MHz frequency, HCSL output, 3.3V supply, and 6-SMD package. Verify pinout compatibility and thermal characteristics. Consult SiTime documentation for cross-reference options if specific pull ranges differ.
