Oscillators Procurement Notes

Verify the specific suffix codes against official SiTime documentation to ensure correct output type, voltage, and tolerance specifications. Confirm package availability and lead times through authorized distributors. Ensure ESD protection protocols are followed during handling due to the surface-mount nature of the component.

Oscillators Selection Notes

Select this component when a 500 MHz VCXO with HCSL outputs is required. Consider the ±25 ppm stability and ±45 ppm pull range against system jitter and tuning requirements. Verify that the 2.5V supply voltage aligns with the target board's power rails and that the 7x5mm footprint fits the PCB layout constraints.

Oscillators Part Context

This part belongs to the SiTime Elite Platform family of programmable oscillators. These devices replace traditional quartz crystals and resonators, offering superior shock and vibration resistance. The SIT3373 series specifically targets applications needing voltage-controlled frequency adjustment with low phase noise characteristics.

Oscillators Replacement Considerations
