LFXTAL085870

Overview

The LFXTAL085870 is a parallel fundamental quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 14.7456 MHz with an 18 pF load capacitance. The component features a tolerance of 30 PPM and frequency stability of 50 PPM over the operating temperature range. It utilizes SMD/SMT termination in an HC49S package, measuring 11.4 mm in length, 4.9 mm in width, and 4.3 mm in height. The drive level is specified at 500 uW, and it functions within a temperature range of -20°C to +70°C.

Feature Summary

• Parallel fundamental quartz crystal design
• HC49S surface mount package configuration
• Hermetically sealed metal can construction

Applications

• Clock signal generation for microprocessors
• Timing references for communication systems
• Frequency control in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct tolerance and packaging specifications. Confirm that the HC49S footprint matches the target PCB layout requirements. Check RoHS compliance status if required by project regulations. Ensure the drive level specification aligns with the oscillator circuit design to prevent frequency drift or damage.

Selection Notes

Select this component when a standard 14.7456 MHz reference is required in a compact surface-mount form factor. The HC49S package offers a balance between size and mechanical robustness. Consider the 50 PPM stability requirement for the application environment. Verify that the 18 pF load capacitance matches the host circuit's capacitive requirements for accurate frequency tuning.

Part Context

This part belongs to the LFXTAL series of quartz crystals from IQD Frequency Products. The series provides various frequencies and packages for general timing applications. The LFXTAL085870 specifically addresses needs for 14.7456 MHz timing in space-constrained designs using the common HC49S outline.

Replacement Considerations

Direct substitutes must match the 14.7456 MHz frequency, 18 pF load capacitance, and HC49S package dimensions. Verify equivalent electrical parameters such as tolerance and stability before substitution.
