LFSPXO069243

Overview

The LFSPXO069243 is a standard clock oscillator from the IQXO-794 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 50 MHz with a frequency stability of ±25 ppm. The device utilizes HCMOS output format and requires a supply voltage of 1.8 V, drawing a maximum current of 10 mA. It features an enable/disable function for standby power management, consuming only 10 µA in disabled mode. The component is housed in a compact 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a maximum height of 1.00 mm. It supports surface mount installation and functions within an operating temperature range of -20°C to +70°C.

Feature Summary

• Supports low-power standby operation via enable/disable control
• Delivers stable HCMOS clock signals with high frequency accuracy
• Designed for space-constrained surface-mount applications

Applications

• Portable consumer electronics requiring low power consumption
• Mobile communication devices needing precise timing references
• Embedded systems utilizing 1.8V logic interfaces

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as availability may vary between cut tape, reel, or Digi-Reel formats. Confirm that the 1.8V supply requirement aligns with your system design, as this model does not support wider voltage ranges. Ensure thermal management accounts for the specified -20°C to +70°C operational window during integration.

Selection Notes

Select this component when a small footprint and low voltage operation are critical constraints. The 2.5mm x 2.0mm package size makes it suitable for dense PCB layouts where larger oscillators cannot fit. Consider the ±25 ppm stability sufficient for general digital timing needs, but verify if tighter tolerance is required for synchronous data links.

Part Context

This part belongs to the IQXO-794 series of ultra-small surface-mount crystal oscillators. The series focuses on miniaturization while maintaining reliable performance for portable applications. IQD Frequency Products designs these components to meet the demands of modern mobile and handheld devices that require minimal power draw and physical space.

Replacement Considerations

Direct substitutes within the same series include other LFSPXO variants with different frequencies or voltages. Cross-reference pinout compatibility and electrical specifications before swapping models to ensure signal integrity and power requirements match the existing circuit design.
