LFXTAL026396

Overview

The LFXTAL026396 is a surface-mount quartz crystal from the 12SMX-B series, designed for precision timing applications. It operates at a nominal frequency of 24.576 MHz with a frequency tolerance of ±30 ppm and total frequency stability of ±50 ppm across the operating temperature range. The component features a 16 pF load capacitance and a maximum equivalent series resistance (ESR) of 40 Ohms. It utilizes a 4-pin 7.0 x 5.0 mm SMD package with a height of 1.4 mm. The device supports a drive level of up to 100 µW and exhibits an annual aging rate of ≤±5 ppm/year.

Feature Summary

• Features a hermetically sealed metal can construction providing robust environmental protection against moisture and contaminants.
• Delivers high frequency stability within a compact 7x5mm surface-mount footprint suitable for space-constrained designs.
• Optimized for low phase noise performance in fundamental mode operation.

Applications

• Industrial USB audio acquisition cards
• Audio ADC/DAC clock generation
• I2S interface synchronization

Procurement Notes

Verify the specific suffix and revision code on the ordering information to ensure compatibility with current manufacturing standards. Confirm that the required frequency tolerance and stability meet the system design specifications before finalizing procurement. Check official distributor channels for availability as supply status may vary.

Selection Notes

Select this component when a 24.576 MHz fundamental frequency is required for digital audio interfaces. Ensure the host circuit supports a 16 pF load capacitance. Verify that the PCB layout accommodates the 7.0 x 5.0 mm package dimensions and that the thermal profile during reflow soldering remains within specified limits for hermetic packages.

Part Context

This part belongs to the IQD 12SMX-B series of surface-mount crystals. It is engineered for applications demanding precise timing in harsh environments. The series is characterized by its metal sealing technology, which distinguishes it from standard epoxy-sealed ceramic packages.

Replacement Considerations

Direct substitutes must match the 24.576 MHz frequency, 16 pF load capacitance, and 7x5mm SMD package. Verify that alternative components offer comparable ESR and stability ratings to maintain system performance.
