LFSPXO019805

Overview

The LFSPXO019805 is a standard crystal oscillator from the CFPS-72 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 48 MHz with an HCMOS/TTL output format. The device requires a single 5V supply voltage and features enable/disable functionality. It is housed in a compact 4-SMD, no-lead package measuring 7.20mm x 5.20mm x 1.40mm. The unit supports a wide operating temperature range from -40°C to +85°C and maintains a frequency stability of ±50 ppm. Maximum current consumption is rated at 50 mA.

Feature Summary

• Integrated enable and disable control function for power management
• HCMOS and TTL compatible output logic levels
• Surface-mount construction with lead-free termination
• Wide industrial temperature rating for robust operation

Applications

• General purpose clock signal generation in embedded systems
• Data communication interface timing sources
• Microcontroller system clock inputs
• Digital signal processing circuit synchronization

Procurement Notes

Verify the specific suffix designation when ordering, as packaging options include tape and reel, cut tape, or Digi-Reel formats. Confirm that the required supply voltage matches the 5V specification, as this model does not support lower voltage rails like 3.3V. Ensure the PCB footprint accommodates the 4-SMD no-lead package dimensions. Check availability status as inventory levels fluctuate across distributors.

Selection Notes

Select this component when a 48 MHz reference is required with moderate stability requirements. The 5V supply constraint distinguishes it from lower voltage alternatives. Consider the enable pin requirement if power cycling is necessary. Compare against the CFPS-73 series if tighter stability or different voltage ranges are needed. Verify thermal performance within the specified -40°C to +85°C window for the target environment.

Part Context

This oscillator belongs to the CFPS-72 product line, which focuses on standard XO solutions. It shares the physical footprint with other variants in the series but differs in electrical specifications such as frequency and voltage. The part represents a surface-mount solution designed for high-volume manufacturing integration into digital circuits requiring precise timing references.

Replacement Considerations

Direct substitutes may include other 48 MHz HCMOS oscillators in similar SMD packages. Cross-reference with IQD's CFPS-73 series for updated versions or alternative frequencies. Verify pin compatibility and electrical parameters before swapping with generic market equivalents.
