LFSPXO018039BULK

Overview

The LFSPXO018039BULK is a standard clock oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a frequency stability of 50 PPM. The device utilizes an HCMOS output format and requires a supply voltage ranging from 4.5 V to 5.5 V. It features a surface-mount package measuring 7 mm x 5 mm. The component is designed for operation within a temperature range of 0°C to +70°C.

Feature Summary

• Provides stable 20 MHz timing signals with 50 PPM accuracy
• Compatible with HCMOS and TTL logic interfaces
• Operates on a single 5V power supply rail

Applications

• General purpose digital system clock generation
• Microprocessor and microcontroller timing sources
• Data communication interface synchronization

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 7mm x 5mm footprint matches the target PCB layout. Ensure the supply voltage remains within the specified 4.5V to 5.5V limits during operation to maintain frequency stability.

Selection Notes

Select this component when a 20 MHz reference signal is required for commercial-grade applications. It is suitable for designs constrained by a 7mm x 5mm SMD footprint. Consider the 50 PPM stability limit for timing-sensitive circuits. Verify compatibility with downstream logic levels if TTL interfacing is intended.

Part Context

This part belongs to the LFSPXO series of standard oscillators from IQD Frequency Products. These components are quartz-based devices designed to replace discrete crystal resonators and external driver circuits. The series offers a compact solution for generating precise clock signals in space-constrained electronic assemblies.

Replacement Considerations

Cross-reference with other 20 MHz, 50 PPM, 7x5mm HCMOS oscillators from IQD or other manufacturers. Ensure pinout compatibility and electrical specifications match exactly. Verify that alternative parts meet the same thermal and voltage requirements.
