Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure compatibility with required voltage levels, output formats, and frequency tolerances. Confirm that the ordering information matches the exact part number designation for the XXE variant to avoid mismatches in electrical characteristics or packaging specifications.

Oscillators Selection Notes

Select this component when a fixed-frequency differential clock source is required for LVDS-compatible circuits. Ensure the design accommodates the 2.25 V to 3.63 V supply range and the -20°C to +70°C operating temperature window. Verify that the 25 ppm stability meets the system's jitter and phase noise requirements.

Oscillators Part Context

This model belongs to the SiT9120 series of high-performance fixed-frequency differential oscillators. The series offers various package sizes including 3225, 5032, and 7050, supporting frequencies from 25 MHz to 212.5 MHz with RMS phase jitter as low as 0.6 ps typical.

Oscillators Replacement Considerations

Direct substitutes include other SiT9120 variants with matching 148.5 MHz frequency, LVDS output, and 3225 package dimensions. Cross-referencing with SiTime's selection tool is recommended to identify equivalent parts with adjusted stability or voltage parameters if minor deviations are acceptable.
