• Industrial control systems

Oscillators Procurement Notes

Verify the specific suffix codes against the official SiTime datasheet to ensure exact electrical parameters match design requirements. Confirm that the 1.8V supply voltage and 19.2MHz frequency align with target circuit specifications. Check for RoHS compliance status if required by project standards. Ensure the selected package size fits the PCB footprint constraints.

Oscillators Selection Notes

Select this part when a compact 3.2x2.5mm footprint is required alongside strict 1.8V operation. The ±25 ppm stability suits applications needing moderate precision without the cost of higher-grade parts. Consider the LVCMOS output compatibility with downstream logic levels. Evaluate thermal performance within the -40°C to +85°C range for environmental suitability.

Oscillators Part Context

This component belongs to the SiT1602 family of silicon MEMS oscillators from SiTime. The family is designed to replace quartz crystals and resonators, offering superior performance in terms of frequency stability and robustness. The BI variant indicates specific packaging and pinout configurations suitable for surface-mount assembly in modern electronic devices.

Oscillators Replacement Considerations

SiTime states that the SiT1602 and SiT800x families can replace all Silicon Labs CMEMS oscillators. Cross-reference tools should be used to identify equivalent footprint-compatible parts from other manufacturers if second-sourcing is necessary.
