ISM95-6251AH-25.000MHZ

Oscillators Overview

The ISM95-6251AH-25.000MHZ is a standard CMOS crystal oscillator manufactured by ILSI America LLC. It operates at a frequency of 25 MHz and requires a supply voltage of 2.5V. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, no-lead ceramic package with dimensions of 2.0 mm x 2.5 mm. The output load specification is 15 pF, and the terminal finish is gold over nickel.

Oscillators Feature Summary

• CMOS output signal compatible with TTL/HC-MOS logic levels
• Integrated enable/disable pin for active power control
• Compact surface-mount ceramic package design

Oscillators Applications

• Digital clock generation in embedded systems
• Microcontroller system timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify the manufacturer designation carefully, as the ISM95 series may be associated with ABRACON or ILSI depending on the specific distribution channel and document version. Confirm the exact suffix 'AH' corresponds to the 2.5V operation and ceramic package variant. Ensure the datasheet matches the 25 MHz frequency requirement and check for any specific environmental compliance documentation required for the project.

Oscillators Selection Notes

Select this component when a low-voltage 2.5V CMOS oscillator is required for space-constrained designs. The 2.0 mm x 2.5 mm footprint is suitable for high-density PCB layouts. Consider the enable/disable feature if power efficiency during idle states is a critical design parameter compared to continuously running oscillators.

Oscillators Part Context

This part belongs to the ISM95 series of surface-mount oscillators. The series includes various frequencies and voltage options, such as 3.3V variants. The 'AH' suffix typically denotes specific electrical characteristics and packaging materials within the ILSI product line, distinguishing it from other series members like the ISM95-6251BH.

Oscillators Replacement Considerations

Direct substitutes include other ISM95 series parts with identical footprints and electrical specs, such as ISM95-6251AH-24.000MHZ or ISM95-6251AH-16.000MHZ, provided the frequency difference is acceptable. Cross-reference with ABRACON equivalents if the source indicates shared manufacturing.
