LFSPXO018538BULK

Overview

The LFSPXO018538BULK is a standard clock oscillator manufactured by IQD Frequency Products. It operates at a frequency of 14.31818 MHz with an HCMOS output format. The device supports a supply voltage range of 2.97 V to 3.63 V and offers a frequency stability of 50 PPM. It is housed in a surface-mount package measuring 7 mm x 5 mm, with physical dimensions of 7.2 mm length, 5.2 mm width, and 1.8 mm height. The component functions within a temperature range of 0°C to +70°C.

Feature Summary

• Generates a precise 14.31818 MHz clock signal using HCMOS logic levels for digital circuit compatibility.
• Provides stable frequency performance with 50 PPM tolerance across the specified operating temperature range.
• Features a compact surface-mount ceramic package designed for automated PCB assembly processes.

Applications

• Clock generation for microprocessors and microcontrollers requiring 14.31818 MHz timing.
• Synchronization sources for communication interfaces and data transmission systems.
• Timing references in industrial control equipment and embedded computing modules.

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as bulk packaging may differ from tape-and-reel options. Confirm that the 0°C to +70°C commercial temperature grade aligns with the target application environment requirements. Ensure the 3.3V nominal supply voltage matches the system power rails before integration into the design.

Selection Notes

Select this component when a fixed 14.31818 MHz frequency is required for digital logic synchronization. The HCMOS output ensures direct interfacing with standard logic families without additional buffering. Consider the 50 PPM stability sufficient for general-purpose timing applications where higher precision oscillators are not necessary or cost-prohibitive.

Part Context

This part belongs to the LFSPXO series of standard clock oscillators from IQD Frequency Products. These devices are designed to replace discrete crystal resonators and load capacitors, providing a ready-to-use clock source. The series includes various frequencies and packages, with this model specifically addressing common microprocessor clock needs in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other manufacturers' 14.31818 MHz HCMOS oscillators in 7x5mm packages, such as those from Epson or SiTime, provided pinout and electrical specifications match. Verify that alternative parts support the same 3.3V supply and 50 PPM stability requirement to ensure functional equivalence in the circuit.
