LFSPXO009437

Overview

The IQD LFSPXO009437 is a standard HCMOS crystal oscillator operating at a nominal frequency of 100 MHz. It utilizes the CFPS-73 series, housed in a hermetically sealed 7x5 mm ceramic package with a welded metal lid. The device operates on a 3.3V supply (2.97V to 3.63V) and draws a typical current of 40mA. It features a full temperature frequency stability of ±50ppm across the 0°C to +70°C range. The output supports a maximum capacitive load of 15pF with rise/fall times under 4ns. An enable/disable function allows for low-power standby modes.

Feature Summary

• Hermetically sealed ceramic construction with welded metal lid for enhanced environmental resistance
• Integrated enable and disable control pin for power management and clock gating
• HCMOS logic compatible output format ensuring broad digital interface compatibility

Applications

• Reference clock source for Gigabit Ethernet PHY transceivers
• Master clock generation for FPGA logic circuits
• Sampling clock input for analog-to-digital converters (ADCs)

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the correct tape-and-reel or bulk packaging configuration. Ensure that the selected variant matches the required lead frame material and terminal finish specifications for your assembly process. Cross-reference the datasheet revision number to guarantee alignment with the latest electrical parameters and mechanical dimensions before finalizing procurement orders.

Selection Notes

Select this component when a robust, hermetically sealed oscillator is required for high-frequency timing applications. The 100MHz frequency aligns with common Gigabit Ethernet standards. The ±50ppm stability is suitable for general-purpose digital systems but may require tighter tolerance models for precision measurement equipment. Consider the 40mA current consumption relative to system power budgets and utilize the enable pin for energy efficiency in battery-operated designs.

Part Context

This part belongs to the CFPS-73 series from IQD Frequency Products, a subsidiary of Würth Elektronik. The series specializes in small-footprint, high-performance surface-mount oscillators designed for demanding industrial and communication environments. The hermetic sealing distinguishes it from standard plastic-packaged alternatives, offering superior reliability against moisture and chemical exposure in harsh operational conditions.
