LFSPXO019137BULK

Overview

The LFSPXO019137BULK is a surface-mount crystal clock oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with HCMOS and TTL output compatibility. The device features a frequency stability of ±50 ppm across an operating temperature range of -40°C to +85°C. It is housed in a compact 4-SMD, no-lead package measuring 7 mm x 5 mm. The component supports a supply voltage of 5V and is designed for standard clock signal generation applications requiring reliable timing performance.

Feature Summary

• Provides stable 40 MHz clock signals with dual HCMOS and TTL output logic levels.
• Maintains ±50 ppm frequency stability over the extended industrial temperature range of -40°C to +85°C.
• Utilizes a compact 4-SMD no-lead surface mount package for efficient PCB integration.

Applications

• General-purpose digital system clock generation
• Microcontroller and processor timing sources
• Industrial control equipment synchronization

Procurement Notes

Verify the specific output logic level requirements against the datasheet specifications before procurement. Confirm that the 5V supply voltage aligns with the target circuit design. Ensure the 4-SMD footprint dimensions match the intended PCB layout constraints. Check for any RoHS compliance documentation if required by project standards.

Selection Notes

Select this component when a 40 MHz reference is needed with broad temperature tolerance. The dual HCMOS/TTL outputs offer flexibility for interfacing with various logic families. Consider the ±50 ppm stability sufficient for most general digital applications. Evaluate the 5V supply requirement against available power rails in the system architecture.

Part Context

This part belongs to the IQD Frequency Products LFSPXO series of standard crystal oscillators. It is designed as a drop-in replacement for other 40 MHz oscillators with similar form factors and electrical characteristics. The bulk packaging option indicates availability for high-volume manufacturing processes requiring reel or tray handling.

Replacement Considerations

Direct substitutes include other 40 MHz HCMOS/TTL oscillators in 7x5mm packages from manufacturers such as Epson, NDK, or SiTime. Verify pinout compatibility and supply voltage tolerances when cross-referencing alternative brands. Ensure frequency stability and temperature range meet or exceed the original specification.
