Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required frequency, output type, and voltage specifications. Confirm the package dimensions and reflow profile requirements align with the manufacturing notes provided in the official datasheet. Ensure the temperature range and stability parameters meet the target application's environmental constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a differential VCXO with high immunity to mechanical and thermal disturbances is required. The integrated noise filtering simplifies board design by removing external linear regulators. Consider the programmability for custom frequency and pull range needs, which reduces lead times compared to traditional quartz solutions. Verify compatibility with LVDS input/output interfaces in the system architecture.

Oscillators Part Context

This part belongs to the SiT3373 family of ultra-low jitter differential MEMS VCXOs. The family supports frequencies from 1 MHz to 725 MHz and offers multiple output types including LVPECL, LVDS, and HCSL. The SiT3373 series is designed for telecom, networking, and industrial sectors, providing exceptional phase noise and linearity while allowing factory programming for specific application requirements.

Oscillators Replacement Considerations

Direct substitutes include other SiT3373 variants with different frequency or stability ratings, such as SIT3373AC-2B9-33NZ307.695484T. Cross-referencing requires matching the LVDS output, 2.8V operation, and surface mount package form factor. Verify that alternative parts maintain the same temperature range and pull range capabilities for equivalent performance.
