ISM97-1251AH-40.000MHZ

Oscillators Overview

The ISM97-1251AH-40.000MHZ is a surface-mount crystal oscillator manufactured by ILSI, operating at a nominal frequency of 40 MHz. It utilizes a CMOS output logic level and functions with a supply voltage of 1.8 VDC. The component is housed in a compact 4-SMD, no-lead package measuring 3.2 mm x 2.5 mm. It supports an enable/disable control function via Pin 1 and operates within a temperature range of -40°C to +85°C. The device complies with RoHS standards and features gold termination.

Oscillators Feature Summary

• CMOS output logic compatible with low-voltage digital systems
• Integrated enable and disable functionality for power management
• Lead-free processing compliant with environmental standards

Oscillators Applications

• Portable consumer electronics requiring low power consumption
• Embedded systems utilizing 1.8V logic interfaces
• Compact communication modules needing precise clock timing

Oscillators Procurement Notes

Verify the specific suffix 'MHZ' against official ILSI documentation to ensure it denotes the standard 40 MHz frequency variant without additional custom parameters. Confirm that the 1.8V supply requirement aligns with your system design, as this model does not support higher voltage inputs like 3.3V or 5V. Ensure compatibility with the specified 3.2mm x 2.5mm footprint during PCB layout.

Oscillators Selection Notes

Select this component when a low-profile, 1.8V CMOS oscillator is required for space-constrained designs. It is suitable for applications prioritizing power efficiency over high-speed performance. Consider alternative series if TTL outputs or wider voltage ranges are necessary, as this model is strictly optimized for 1.8V CMOS operation.

Oscillators Part Context

This part belongs to the ISM97 series of SMD oscillators from ILSI, designed for general-purpose clock generation in modern electronic devices. The series emphasizes small form factors and low power consumption, making it distinct from larger industrial-grade oscillators. It serves as a standard timing reference for microcontrollers and memory interfaces.

Oscillators Replacement Considerations

Direct substitutes include other 40 MHz, 1.8V CMOS SMD oscillators from ILSI within the ISM97 family, provided they share the identical 3.2x2.5mm package and pinout configuration. Cross-manufacturer replacements require verification of electrical parameters and mechanical dimensions.
