LFSPXO009443

Overview

The LFSPXO009443 is a standard clock oscillator manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a nominal frequency of 80 MHz with a frequency stability of ±50 ppm. The device supports a supply voltage range from 4.5 V minimum to 3.63 V maximum, though typical operation centers around 3.3 V systems in compatible configurations. It features an HCMOS output format and utilizes a 7 mm x 5 mm SMD package. The component is rated for an industrial operating temperature range of 0°C to +70°C, ensuring reliable performance in standard electronic environments.

Feature Summary

• Provides stable 80 MHz timing signals via HCMOS output interface
• Designed for compact surface-mount integration within 7x5mm footprint
• Operates reliably across the specified industrial temperature range

Applications

• General-purpose digital circuit timing
• Microcontroller clock sources
• Communication interface synchronization

Procurement Notes

Verify the specific supply voltage requirements against the target system design, as datasheet specifications indicate a minimum of 4.5V while common applications may utilize 3.3V rails. Confirm availability status through authorized distributors, as lead times and stock levels vary. Ensure the HCMOS output logic levels are compatible with downstream components. Cross-reference the exact suffix and packaging type to match assembly line requirements.

Selection Notes

Select this model when a fixed 80 MHz frequency is required with moderate stability. Consider the 7x5mm package size for board space constraints. Verify that the input voltage range aligns with the power supply architecture. Compare against other IQD series if wider temperature ranges or different output formats like LVDS are needed. Check for end-of-life notifications before finalizing the design.

Part Context

This component belongs to the LFSPXO series of standard crystal oscillators from IQD Frequency Products.
