Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official documentation to ensure correct output type and voltage specifications. Confirm that the XXS designation aligns with the required packaging and tape-and-reel configuration for your manufacturing process. Cross-reference the part number with the latest datasheet to validate environmental compliance and stability ratings before finalizing procurement orders.

Oscillators Selection Notes

Select this model when LVPECL signaling is mandatory for the system architecture. Ensure the design supports the 2.25V to 3.63V input range and accommodates the 6-SMD footprint. Consider the standby feature if power efficiency during idle states is a critical design parameter. Verify that the 212.5 MHz frequency matches the target application requirements without need for additional frequency synthesis.

Oscillators Part Context

This oscillator belongs to the SiT9120 series, which features MEMS resonators offering superior reliability over quartz alternatives. The series supports various frequencies up to 212.5 MHz and includes options for different output types like LVDS and LVPECL. The AC variant typically denotes specific stability and temperature range characteristics defined by SiTime for industrial-grade applications.

Oscillators Replacement Considerations

Direct substitutes include other SiTime models within the SIT9120 family with matching LVPECL outputs and 212.5 MHz frequency, such as SIT9120AC-1B2-25E212.500000 if enable/disable functionality is preferred over standby. Ensure any replacement maintains the same 6-SMD package dimensions and electrical characteristics to guarantee board compatibility.
