Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm the exact pull range and enable/disable functionality. Ensure the voltage supply matches the 3.3V requirement and that the thermal management supports the -40°C to +105°C operational window. Confirm package dimensions align with PCB footprint requirements before finalizing procurement.

Oscillators Selection Notes

Select this component when Stratum 3 compliance and ±100 ppb stability are mandatory. The voltage-controlled feature distinguishes it from standard TCXOs, allowing active frequency adjustment. Consider the 10-SMD package size for space-constrained designs. Verify that the LVCMOS output logic levels match the receiving circuitry interface requirements.

Oscillators Part Context

This part belongs to the SiT5356 Elite Platform series, designed for high-performance timing applications. It represents a transition from traditional quartz oscillators to MEMS technology, offering superior shock resistance and lower power consumption while maintaining stringent telecom-grade stability standards.

Oscillators Replacement Considerations

Direct replacements must match the 10.949297 MHz frequency, 3.3V supply, and 10-SMD package. Cross-reference with other SiTime Super-TCXO models or equivalent Stratum 3 compliant MEMS oscillators from other manufacturers if pin compatibility and electrical parameters align.
