LFSPXO019987

Overview

The LFSPXO019870 is a standard clock oscillator from the CFPS-73 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a frequency stability of 100 PPM. The device utilizes an HCMOS output format and requires a supply voltage ranging from 2.97 V to 3.63 V, typically centered at 3.3 V. It features a load capacitance of 50 pF and a maximum current rating of 20 mA. The unit is housed in a 7 mm x 5 mm surface-mount package with dimensions of 7.2 mm length, 5.2 mm width, and 1.4 mm height. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Hermetically sealed ceramic construction with a seam-sealed metal lid for enhanced reliability
• HCMOS output format compatible with standard digital logic interfaces
• Extended industrial temperature operation capability

Applications

• Clock and timing circuits
• Aerospace systems
• Defence equipment
• Military applications

Procurement Notes

Verify the specific part number suffix against official documentation, as manufacturer revisions may alter identifiers without changing function. Confirm that the ordering suffix corresponds to the required packaging type, such as Reel or Cut Tape, rather than assuming standard bulk availability. Cross-reference the Mouser number 449-LFSPXO019987 for accurate sourcing. Ensure the requested variant matches the exact electrical specifications and package dimensions defined in the datasheet to avoid integration errors during procurement.

Selection Notes

Select this component when hermetic sealing is required for high-reliability environments. The 40 MHz frequency and 100 PPM stability suit general timing needs where extreme precision is not critical. The 3.3V HCMOS interface ensures compatibility with common microcontrollers. Consider the 7x5mm footprint for PCB layout constraints. Verify thermal requirements against the -40C to +85C operational range before finalizing the design choice.
