Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct configuration. Confirm that the required output format, voltage level, and temperature grade match the application requirements. Check for any recent revisions to the part number or pinout definitions before finalizing procurement. Ensure compliance with RoHS3 standards if environmental regulations apply to the end product.

Oscillators Selection Notes

Select this component when superior phase noise and dynamic stability are critical compared to standard TCXOs. The 26 MHz frequency is suitable for specific reference clock applications. Consider the enable pin requirement for power-sensitive designs. Evaluate the 2.5 ppm stability against system jitter budgets. The wide temperature range makes it suitable for harsh environments where standard commercial parts may fail.

Oscillators Part Context

This part belongs to the SiT5156 Elite Platform series, which utilizes silicon MEMS technology to replace traditional quartz oscillators. The platform offers significant size reduction and improved shock/vibration resistance. The 'AE' designation typically indicates specific packaging and temperature characteristics within the SiTime portfolio. This series is designed to meet the rigorous demands of modern high-speed digital interfaces.

Oscillators Replacement Considerations

Direct replacements must match the 26 MHz frequency, 2.5 ppm stability, and 10-SMD package dimensions. Verify compatibility of the clipped sine wave output with the receiving circuit input thresholds. Ensure the replacement part supports the same 2.8V supply and enable logic levels. Cross-reference with other SiT5156 variants only if parameter deviations are acceptable for the specific application.
