LFSPXO021890

Overview

The LFSPXO021890 is a standard crystal clock oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 8 MHz with a frequency stability of ±50 ppm. The device utilizes an HCMOS output signal and requires a supply voltage of 3.3 V, with a maximum supply current of 7 mA. It is housed in a surface-mount ceramic package measuring 7 mm x 5 mm, featuring a seam-sealed metal lid. The component supports an enable/disable function and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• HCMOS output compatibility for digital logic interfacing
• Enable and disable control functionality
• Seam-sealed metal lid construction for environmental protection

Applications

• General-purpose clock signal generation in electronic circuits
• Embedded systems requiring stable timing references
• Industrial equipment operating within extended temperature ranges

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct configuration. Confirm that the required frequency stability, output type, and package dimensions match the design requirements. Check for any specific handling instructions related to the ceramic package and seam-sealed lid during assembly.

Selection Notes

Select this oscillator when a standard 8 MHz clock source with HCMOS output is required. Ensure the application environment falls within the specified -40°C to +85°C temperature range. Consider the 7 mm x 5mm footprint constraints and the need for a 3.3 V supply rail compatible with the 7 mA maximum current draw.

Part Context

This component belongs to the CFPS-73 series of crystal oscillators from IQD Frequency Products. The series offers various frequencies and packages, with this specific model providing a compact SMD solution. It is designed for applications needing reliable timing without the complexity of higher-performance TCXOs or OCXOs.

Replacement Considerations

Consult the manufacturer's official documentation for direct cross-reference part numbers. Verify electrical parameters such as frequency, stability, and output voltage levels before substituting with alternative components from other manufacturers.
