Oscillators Procurement Notes

Verify the specific suffix codes (AC, 2C3, 25E) against the manufacturer's official datasheet to ensure correct voltage, temperature grade, and packaging configuration. Confirm that the LVDS output type matches the receiving circuit requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the 6-SMD footprint dimensions align with the PCB layout constraints.

Oscillators Selection Notes

Select this component when a 108 MHz frequency with LVDS outputs is required in a compact surface-mount package. Consider the ±25ppm stability specification relative to system timing budgets. Evaluate the 2.5V supply requirement against available board voltages. The wide operating temperature range makes it suitable for industrial or automotive contexts where standard commercial grades may be insufficient.

Oscillators Part Context

The SIT9121AC-2C3-25E108.000000 belongs to the SiTime SiT9121 series of programmable MEMS oscillators. This series replaces traditional quartz crystals with silicon-based solutions, offering superior performance in terms of size, robustness, and programmability. The part integrates the resonator and oscillator circuitry on a single chip, providing a complete clock solution in a small form factor.

Oscillators Replacement Considerations

Direct replacements must match the 108 MHz frequency, LVDS output, 2.5V supply, and 6-SMD package. Verify compatibility with any existing firmware or hardware configurations that rely on the specific enable/disable behavior. Cross-reference with other SiT9121 variants for potential upgrades in stability or temperature range if system requirements change.
