Oscillators Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to ensure correct output signaling and voltage levels. Confirm that the 6-SMD package dimensions align with your PCB footprint requirements. Ensure the specified temperature range meets your operational environment constraints before finalizing procurement.

Oscillators Selection Notes

Select this model when a differential VCXO with HCSL outputs is required for frequencies above 220 MHz. Consider its integrated regulation capabilities if board space for external components is limited. Evaluate its programmability against fixed-frequency quartz alternatives to optimize lead times and customization costs for specific network configurations.

Oscillators Part Context

This component belongs to the SiT3373 family of ultra-low jitter differential MEMS VCXOs. The series covers frequencies from 220 MHz to 725 MHz and utilizes TurboCompensation technology. It is designed to replace traditional quartz oscillators in applications requiring precise frequency control and resilience to environmental stressors.

Oscillators Replacement Considerations

Direct substitutes include other variants within the SiT3373 family such as the SIT3373AC-2E3-33NX280.550000, which shares similar specifications but differs in supply voltage and output type. Verify pin compatibility and electrical parameters before substitution.
