LFSPXO019137

Overview

The IQD Frequency Products LFSPXO019137 is a standard clock oscillator generating a nominal frequency of 40.0 MHz. It operates on a single 5V supply voltage, with an acceptable range of 4.5 V to 5.5 V. The device provides both HCMOS and TTL output formats for versatile digital interface compatibility. It maintains a frequency stability of ±50 ppm over the operating temperature range. The component utilizes a surface-mount package measuring 7.0 mm by 5.0 mm with a height of 1.4 mm. It supports an industrial temperature range from 0°C to +70°C and includes enable/disable functionality.

Feature Summary

• Dual output format support for HCMOS and TTL logic levels
• Integrated enable and disable control function
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• General purpose digital system clocking
• Industrial control equipment timing
• Communication interface synchronization

Procurement Notes

Verify the specific orderable part number against manufacturer documentation, as distributor listings may vary in suffixes or packaging options. Confirm that the 5V supply requirement aligns with the target circuit design, as this model differs from lower-voltage variants. Ensure the ±50 ppm stability meets the application's timing tolerance requirements before finalizing procurement.

Selection Notes

Select this component when a 40 MHz reference signal is required with 5V logic compatibility. The dual HCMOS/TTL outputs simplify interfacing with mixed-logic systems. Consider the ±50 ppm stability adequate for general applications but insufficient for high-precision timing needs. The enable pin allows for power management integration within the system architecture.
