LFSPXO082150

Overview

The LFSPXO082150 is a standard CMOS clock oscillator from the IQXO-540 series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 19.2 MHz and utilizes a compact 2 mm x 1.6 mm surface-mount package with a ceramic body and hermetically sealed metal lid. The device supports a supply voltage range of 1.62 V to 3.63 V and features HCMOS output. It provides a frequency stability of ±25 ppm over the industrial temperature range of -40°C to +85°C, ensuring reliable timing for communication interfaces.

Feature Summary

• Hermetically sealed ceramic construction with metal lid for enhanced environmental protection
• Compact 2 mm x 1.6 mm footprint suitable for space-constrained designs
• Low power consumption with standby capability
• Industrial grade stability across wide temperature variations

Applications

• Bluetooth Low Energy (BLE) reference clocks
• LoRa module timing sources
• Cat.1 cellular modem synchronization
• Industrial sensor interface clocks

Procurement Notes

Verify the specific ordering suffix to confirm the exact frequency tolerance and packaging configuration. Ensure the selected variant matches the required operating temperature range and supply voltage constraints. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential pinout or parameter updates before finalizing the design.

Selection Notes

Select this component when a small form factor and high reliability are critical. The 19.2 MHz frequency is ideal for wireless protocols requiring precise timing without frequency conversion. Consider the hermetic seal for harsh environments where plastic-packaged oscillators may fail due to moisture ingress. Compare total drift specifications against application requirements to ensure signal integrity.

Part Context

This part belongs to the IQXO-540 series, which focuses on industrial-grade performance in miniature packages. Unlike consumer-grade alternatives, these oscillators offer superior resistance to humidity and corrosion. The series is designed for applications demanding long-term stability and robust operation in challenging conditions.

Replacement Considerations

Direct substitutes include other 19.2 MHz oscillators in 2016 packages with similar stability. Verify that replacement parts match the hermetic sealing requirement if environmental resistance is critical. Check compatibility with existing PCB footprints and supply voltage levels.
