LFSPXO026068

Overview

The IQD LFSPXO026068 is a standard clock oscillator operating at a nominal frequency of 40 MHz. It utilizes HCMOS output levels and maintains a frequency stability of ±50 ppm. The device functions within a supply voltage range of 2.97 V to 3.63 V, with a typical operating voltage of 3.3 V. It features a surface-mount package measuring 7 mm by 5 mm with a height of 1.4 mm. The component supports a four-pin configuration and includes standby mode functionality for power management.

Feature Summary

• Provides stable 40 MHz timing signals via HCMOS output interface
• Integrates standby mode capability for reduced power consumption during idle states
• Utilizes surface-mount ceramic packaging with hermetically sealed metal lid construction

Applications

• Standard clock generation in digital communication systems
• Timing reference sources for microprocessor-based embedded designs
• Clock distribution networks requiring low-power operation

Procurement Notes

Verify the specific suffix designation when ordering, as variations exist regarding frequency stability tolerances and packaging formats such as bulk or reel configurations. Confirm that the selected variant matches the required ±50 ppm stability specification and operates within the specified 3.3 V supply constraints. Ensure compatibility with the 7 mm x 5 mm footprint and verify RoHS compliance status for the intended manufacturing process.

Selection Notes

Select this component when a precise 40 MHz reference is required with moderate stability requirements. The HCMOS output ensures direct interfacing with standard logic families without additional buffering. Consider the standby feature if system power efficiency is a priority. Evaluate the thermal operating range against environmental conditions, noting the standard industrial temperature specifications provided in official documentation.

Part Context

This oscillator belongs to the IQD LFSPXO series, designed for general-purpose timing applications. It represents a compact solution for replacing through-hole crystals with integrated oscillator circuits. The product line emphasizes reliability and ease of integration into modern printed circuit board layouts, offering a drop-in replacement for discrete crystal assemblies in space-constrained electronic modules.

Replacement Considerations

Cross-reference part numbers such as LFSPXO026068BULK for alternative packaging options. Verify pinout compatibility and electrical parameters before substituting with other manufacturers' 40 MHz HCMOS oscillators. Ensure that any replacement maintains the same physical dimensions and voltage tolerance limits.
