LFSPXO019805BULK

Overview

The LFSPXO019805BULK is a standard crystal oscillator (XO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 48 MHz with an output format of HCMOS/TTL. The device is powered by a single 5V supply and draws a maximum current of 50mA. It features a frequency stability of ±50ppm and functions within a temperature range of -40°C to +85°C. The component utilizes a surface-mount package measuring 7.20mm x 5.20mm x 1.40mm, identified as 4-SMD, no lead. This specific bulk packaging variant is part of the CFPS-72 series.

Feature Summary

• Provides stable 48 MHz clock signals using HCMOS/TTL output logic levels for digital circuit compatibility.
• Includes enable/disable functionality to manage power consumption during inactive periods.
• Constructed with a base crystal resonator for reliable frequency generation in standard operating environments.

Applications

• General-purpose digital systems requiring precise timing references
• Microcontroller and processor clock inputs
• Industrial control equipment operating in wide temperature ranges

Procurement Notes

Verify the exact suffix designation when ordering, as LFSPXO019805BULK denotes bulk packaging while other suffixes like TR or CT indicate tape and reel or cut tape options. Confirm that the 5V supply requirement aligns with your system design, as this model differs from lower voltage variants. Ensure the ±50ppm stability meets your application's jitter tolerance requirements before finalizing procurement specifications.

Selection Notes

Select this component when a 48 MHz frequency is required with HCMOS output compatibility. The 5V supply voltage distinguishes it from 3.3V or 1.8V oscillators in the same family. Consider the ±50ppm stability and -40°C to +85°C temperature range against stricter industrial or automotive standards if higher precision is needed. The 4-SMD footprint must fit the designated PCB land pattern.

Part Context

This part belongs to the CFPS-72 series of standard oscillators from IQD Frequency Products. It is distinct from the LFSPXO019835 (48MHz, 3.3V, 25ppm) and LFSPXO019859 (56MHz, 3.3V, 100ppm) models due to its specific voltage, stability, and frequency parameters. The BULK suffix indicates non-reel packaging, differing from the REEL or CUTT variants available for the same electrical specification.

Replacement Considerations

Direct substitutes include other LFSPXO019805 variants with different packaging such as LFSPXO019805REEL or LFSPXO019805CUTT, which share identical electrical characteristics. Cross-model replacements require matching the 48MHz frequency, 5V supply, and HCMOS output format.
