Overview

The LFXTAL033328 is a fundamental mode quartz crystal resonator from the CFPX-104 series by IQD Frequency Products. It operates at a nominal frequency of 14.7456 MHz with a frequency tolerance and stability of ±50 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 70 Ohms maximum. It supports a drive level of 100 µW and functions within a temperature range of -10°C to +60°C. The device utilizes a surface-mount 4-SMD, no-lead package measuring 5.00 mm in length, 3.20 mm in width, and 1.00 mm in height.

Feature Summary

• Fundamental resonance mode operation for stable clock signal generation
• Surface-mount design compatible with automated SMD/SMT assembly processes
• Compliant with RoHS environmental standards for restricted substances

Applications

• Clock source generation for microcontrollers and digital logic circuits
• Timing reference for communication interfaces requiring 14.7456 MHz
• Embedded systems operating within standard commercial temperature ranges

Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as variants exist for bulk and reel formats. Confirm that the required frequency tolerance of ±50 ppm aligns with system timing requirements. Ensure the operating environment remains within the specified -10°C to +60°C range to maintain performance specifications. Check datasheet for recommended soldering profiles to prevent mechanical stress on the ceramic package.

Selection Notes

Select this component when a 14.7456 MHz fundamental frequency is required for serial data transmission or baud rate generation. The 18 pF load capacitance must match the oscillator circuit design to ensure accurate frequency output. Consider the 70 Ohm ESR limit when designing the load capacitors and feedback resistor. This package size offers a compact solution for space-constrained printed circuit board layouts compared to through-hole alternatives.

Part Context

This part belongs to the CFPX-104 series of surface-mount crystals designed for general-purpose timing applications. IQD Frequency Products manufactures these components using precision-cut quartz elements housed in small footprint packages. The series provides options for various frequencies and load capacitances to support diverse electronic designs requiring reliable clock signals.

Replacement Considerations

The part number LFXTAL033328BULK represents the same electrical specifications but differs in packaging format. Verify compatibility with existing pick-and-place equipment if switching between reel and bulk supply methods. No direct cross-manufacturer substitutes are confirmed in public documentation; alternative sources require independent validation of pinout and electrical parameters.
