LFSPXO056242

Overview

The LFSPXO056242 is a standard CMOS clock oscillator from the IQXO-540 series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 24 MHz with a full temperature frequency stability of ±50 ppm across the -40°C to +85°C industrial range. The device utilizes a hermetically sealed metal package measuring 2.0 mm x 1.6 mm x 0.7 mm, ensuring robust environmental protection. It functions on a single 3.3 V supply voltage and features a dedicated standby control pin for power management. The output provides CMOS logic levels capable of driving a 15 pF load, making it suitable for compact industrial designs requiring reliable timing signals.

Feature Summary

• Hermetically sealed metal enclosure providing superior dust and moisture resistance compared to plastic packages
• Integrated standby control function allowing low-power operation via logic level input
• Compact surface-mount footprint designed for space-constrained industrial applications
• CMOS output format compatible with standard digital logic interfaces

Applications

• Industrial edge gateways and compact controllers
• Microcontroller (MCU) system clock generation
• Ethernet PHY interface timing sources
• LoRa and wireless modulation circuit clocks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tolerance specifications. Confirm that the selected variant matches the required operating temperature range and frequency stability for your application. Cross-reference the pinout diagram during PCB layout to ensure proper connection of the standby control and power pins. Validate component authenticity through authorized distribution channels to guarantee reliability in industrial environments.

Selection Notes

Select this oscillator when a small form factor combined with high environmental durability is required. The hermetic seal makes it preferable over plastic-packaged alternatives in harsh conditions involving humidity or particulate exposure. Ensure the design accommodates the 3.3 V supply rail and utilizes the enable pin if power conservation is necessary. Consider the ±50 ppm stability sufficient for most synchronous digital protocols while offering better thermal performance than basic commercial-grade devices.
