LFSPXO017885

Overview

The LFSPXO017885 is a standard clock oscillator from the CFPS-73 series by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a frequency stability of ±50 ppm across an industrial temperature range of -40°C to +85°C. The device utilizes a 3.3 V supply voltage and features an HCMOS output format. It is housed in a 7 mm x 5 mm surface-mount package with a height of 1.4 mm. The component supports enable/disable functionality, drawing a maximum current of 20 mA during operation.

Feature Summary

• Industrial-grade wide temperature operation for reliable performance in harsh environments
• HCMOS output format compatible with standard digital logic interfaces
• Enable/Disable pin functionality for low-power standby modes
• Hermetically sealed ceramic package for enhanced environmental protection

Applications

• Outdoor industrial data acquisition gateways
• Automotive cabin electronics and control units
• High-speed ADC sampling clock sources
• Ethernet PHY peripheral clocks
• MCU system clock generation

Procurement Notes

Verify the specific suffix (Reel) against the required packaging configuration. Confirm that the ±50 ppm stability meets the system timing requirements. Ensure the 3.3V supply rail is stable within the specified operating range. Check for RoHS compliance documentation if exporting to regulated regions. Validate the enable pin logic levels against the target microcontroller outputs.

Selection Notes

Select this component when industrial temperature resilience (-40°C to +85°C) is mandatory. Choose the CFPS-73 series for applications requiring hermetic sealing against moisture or dust. Opt for this model over commercial grades if long-term aging stability is critical. Consider the enable feature for battery-powered systems requiring low standby current. Verify that the 40 MHz frequency aligns with the target peripheral clock requirements.
