Oscillators Procurement Notes

Verify the specific supply voltage requirement of 2.8V against your system design, as this variant differs from standard 3.3V models. Confirm that the LVPECL output interface matches your receiver inputs. Ensure the thermal environment stays within the specified -20°C to +70°C operational range. Check for any required EMI shielding or layout considerations associated with high-speed differential outputs in your PCB design.

Oscillators Selection Notes

Select this model when a wide pull range is necessary alongside high-frequency operation. Compare against other SIT3372 variants to ensure the 2.8V supply aligns with your power architecture. Consider the ±35 ppm stability if tighter tolerances are required, which might necessitate different series options. Evaluate the 6-pin package size against available board space constraints relative to larger oscillator footprints.

Oscillators Part Context

This component belongs to the SiTime Elite Platform family, specifically the SIT3372 series designed for high-performance VCXO applications. It represents a shift from traditional quartz crystals to silicon MEMS resonators, offering improved shock resistance and scalability. The part integrates the resonator, oscillator circuit, and output buffer into a single surface-mount package, simplifying design-in processes for engineers.

Oscillators Replacement Considerations

Direct substitutes may include other SIT3372 variants with adjusted voltage or frequency parameters, such as SIT3372AC-1E9-33NC80.000000 for 3.3V operation. Cross-reference pinout compatibility and electrical characteristics carefully before swapping. Verify that alternative MEMS oscillators meet the same APR and stability requirements for equivalent performance.
