LFSPXO025492

Overview

The LFSPXO025492 is a standard clock oscillator from the IQD CFPS-39 series, manufactured by IQD Frequency Products. It features a 12 MHz nominal frequency with a total frequency deviation of ±50 ppm across the industrial temperature range of -40°C to +85°C. The device operates on a 3.3V supply voltage and draws a typical current of 7 mA. It utilizes a 3.2 x 2.5 mm ceramic package with a seam-sealed metal lid for enhanced environmental protection. The output format is CMOS, supporting a maximum load capacitance of 15 pF.

Feature Summary

• Hermetically sealed ceramic construction with a seam-welded metal top cover provides superior moisture and dust resistance compared to standard plastic packages.
• Integrated standby functionality allows control via the enable pin; high impedance state is achieved at low logic levels with minimal standby current consumption.
• CMOS output compatibility ensures direct interfacing with microcontrollers, ADCs, and Ethernet PHYs without requiring additional signal matching components.

Applications

• LoRa communication modules requiring stable timing
• Industrial serial communication interfaces
• Microcontroller main clock sources
• ADC reference clock applications

Procurement Notes

Verify the specific ordering suffix against official IQD documentation to confirm packaging configuration, as suffixes may indicate variations in reel or cut tape quantities. Ensure the selected variant matches the required frequency stability and operating temperature range for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times prior to finalizing procurement plans.

Selection Notes

Select this component when industrial-grade reliability and environmental sealing are critical for the design. The 3.2x2.5mm footprint offers a balance between size and robustness suitable for harsh conditions. Consider the standby feature if power management during idle states is a priority. Verify that the system power rail aligns with the 3.3V operating requirement and that the CMOS output swing meets the input thresholds of the downstream logic devices.
