LFSPXO082199

Overview

The LFSPXO082199 is a standard clock oscillator from the IQXO-791 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 4 MHz with a frequency stability of ±25 ppm. The device utilizes an HCMOS output format and requires a nominal supply voltage of 3.3 V. It is housed in a compact surface-mount package measuring 2.5 mm by 2.0 mm, designed for efficient PCB integration.

Feature Summary

• Compact SMD footprint suitable for space-constrained designs
• HCMOS output interface for digital logic compatibility
• Standard frequency stability for general timing applications

Applications

• General purpose digital circuit timing
• Embedded system clock generation
• Consumer electronics timing references

Procurement Notes

Verify the specific package dimensions against current official datasheets prior to procurement, as component specifications may evolve. Confirm that the 2.5 mm x 2.0 mm form factor aligns with your PCB land pattern requirements. Ensure the HCMOS output voltage levels are compatible with your target logic family before finalizing the order.

Selection Notes

Select this model when a low-cost, small-footprint oscillator is required for non-critical timing applications. The 25 ppm stability is adequate for standard microcontrollers but insufficient for high-precision communication interfaces. Consider larger packages or higher stability grades if thermal drift or phase noise performance is a primary design constraint.

Part Context

This component belongs to the IQXO-791 series, which provides basic clock signals in miniature surface-mount packages. The series targets cost-sensitive applications where extreme precision is not mandatory. It serves as a fundamental timing source for simple digital logic and microcontroller systems within the broader IQD Frequency Products portfolio.

Replacement Considerations

Cross-reference with other IQD models in the same series offering identical 4 MHz frequency and 3.3V operation. Verify mechanical compatibility with the 2.5mm x 2.0mm package size. Electrical parameters such as load current and rise/fall times should be compared to ensure functional equivalence in the existing circuit design.
