Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official configuration tool to ensure correct pull range and stability specifications. Confirm that the HCSL output type matches the receiving circuit requirements. Check for any updated revision codes or alternative pinout configurations before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 281 MHz reference with HCSL outputs is required. Ensure the system design accommodates the 3.3V supply rail and the specified ±50 ppm stability. Consider the thermal environment to guarantee operation within the -40°C to 85°C range without derating performance.

Oscillators Part Context

This part belongs to the SiTime Elite Platform series, which leverages silicon MEMS technology to replace traditional quartz crystals. The SIT3373 family provides programmable oscillators with integrated tuning capabilities, offering superior shock and vibration resistance compared to bulk acoustic wave devices.

Oscillators Replacement Considerations

Direct replacements must match the 281 MHz frequency, HCSL output, and 3.3V supply. Verify pin compatibility for the 6-SMD package. Cross-reference with other SiTime models like the SIT3373AC series if different stability or pull ranges are acceptable.
