LFSPXO082146

Overview

The LFSPXO082146 is a standard clock oscillator manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a nominal frequency of 4 MHz with a full temperature frequency stability of ±25 ppm across the industrial range of -20°C to +70°C. The device features an HCMOS output format and is powered by a single supply voltage ranging from 2.97 V to 3.63 V, typically centered at 3.3 V. Physically, it utilizes a compact 2 mm x 1.6 mm ceramic package sealed with a metal lid, ensuring robust performance in demanding environments.

Feature Summary

• Hermetically sealed ceramic construction with a seam seal metal lid for enhanced moisture resistance
• Industrial-grade frequency stability suitable for precise timing requirements
• Low power consumption characteristics optimized for battery-operated systems

Applications

• External clock input for 32-bit microcontrollers
• Low-speed serial communication interfaces such as UART and SPI
• Consumer electronics requiring reliable timing sources

Procurement Notes

Verify the specific ordering suffix when purchasing, as packaging options vary. The part may be available in bulk quantities or tape-and-reel formats depending on distributor stock. Confirm that the selected variant matches the required operating temperature range and output drive strength for your specific circuit design before finalizing orders.

Selection Notes

Select this component when a small footprint and high reliability are prioritized over ultra-high precision. It serves as a direct replacement for larger oscillators where space is constrained. Ensure the host circuit supports the HCMOS logic levels and the supply voltage remains within the specified operational limits to guarantee stable frequency generation.
