Oscillators Procurement Notes

Verify the specific frequency stability requirement (±20, ±25, or ±50 ppm) against the datasheet, as the base model number may not explicitly denote the selected tolerance tier. Confirm that the 3.3V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints. Cross-reference the enable/disable functionality if power management is required in the final application.

Oscillators Selection Notes

Select this component when military-grade temperature ranges (-55°C to +125°C) and high mechanical ruggedness are critical. It is suitable for designs requiring LVCMOS/LVTTL outputs without differential signaling needs. Consider alternative SiTime series if lower power consumption or smaller form factors like 2.0x1.6mm are prioritized over the 5.0x3.2mm package size offered by this specific variant.

Oscillators Part Context

This part belongs to the SiT8920 series, which utilizes silicon MEMS technology to replace traditional quartz oscillators. The series is designed for harsh environments, offering superior shock and vibration performance compared to quartz. It supports frequencies from 1 to 110 MHz and provides field programmability, enabling rapid prototyping and inventory reduction by using a single part number for multiple frequency configurations.

Oscillators Replacement Considerations

Direct replacement requires verifying pin compatibility and electrical specifications. While other SiTime models like the SiT1602 offer similar frequencies, they may differ in temperature range or package size. Ensure any substitute maintains the -55°C to +125°C operating range and LVCMOS/LVTTL output drive strength to guarantee system integrity in aerospace or industrial applications.
