LFSPXO056249

Overview

The LFSPXO056249 is a standard clock oscillator from the IQXO-540 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 50 MHz with a frequency stability of ±50 ppm. The device utilizes CMOS output format and requires a supply voltage ranging from 2.97 V to 3.63 V, typically centered at 3.3 V. It features an SMD/SMT termination style within a compact ceramic package measuring 2.0 mm in length, 1.6 mm in width, and 0.7 mm in height. The component supports operation across a temperature range from -40°C to +85°C.

Feature Summary

• Hermetically sealed ceramic package with seam-sealed metal lid for environmental protection
• CMOS output format compatible with standard digital logic interfaces
• Compact surface-mount footprint suitable for space-constrained PCB layouts

Applications

• General purpose timing reference for embedded systems
• Clock source for microcontrollers and processors
• Data communication interface synchronization

Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as variants exist in cut tape or reel formats. Ensure the required frequency tolerance and operating temperature range align with system specifications before procurement. Cross-reference the manufacturer part number with official IQD documentation to confirm current production status and RoHS compliance details.

Selection Notes

Select this component when a low-profile, hermetically sealed oscillator is required for 50 MHz applications. Consider the ±50 ppm stability limit against system jitter requirements. Evaluate the 3.3 V supply constraint against available power rails. Compare physical dimensions against board space limitations relative to alternative packages.

Part Context

This part belongs to the IQXO-540 series of standard crystal oscillators. The series offers various frequencies and package sizes, with the LFSPXO056249 representing the 2.0 x 1.6 mm form factor. It is designed for general industrial and commercial use where moderate stability and small size are prioritized over high-performance phase noise characteristics.

Replacement Considerations

Direct substitutes within the same series include other LFSPXO0562xx variants with different frequencies but identical pinouts and electrical characteristics. Verify that any replacement maintains the same package dimensions and CMOS output compatibility.
