Oscillators Procurement Notes

Verify the exact ordering suffix against the manufacturer's official datasheet to ensure compatibility with your specific design requirements. Confirm that the 2.8V supply voltage and LVPECL output levels match your system's power rails and input thresholds. Check the 6-SMD, No Lead package dimensions for PCB footprint accuracy. Ensure the factory-programmed parameters align with your application's frequency and pull range needs before finalizing procurement.

Oscillators Selection Notes

Select this component when designing systems that require robust performance under dynamic conditions such as shock, vibration, and thermal gradients. The integrated noise filtering capabilities make it suitable for noisy power environments where external regulation is undesirable. Consider this part for applications needing customizable frequency and pull ranges to optimize clock configurations without custom quartz manufacturing delays.

Oscillators Part Context

This model belongs to the SiT3372 family of differential MEMS VCXOs, engineered for frequencies between 1 MHz and 220 MHz. The series is designed to replace traditional quartz oscillators by offering superior resilience to environmental stressors and shorter lead times through programmability. It supports various output signaling types and voltages within the same core technology platform.

Oscillators Replacement Considerations

Direct replacement requires matching the 76.8 MHz frequency, 2.8V operation, LVPECL outputs, and 6-SMD package. Verify that any substitute component supports the required pull range and jitter specifications. Ensure the alternative device also offers MEMS-based durability if environmental resistance is critical to the application.
