ISM97-6251AH-40.000MHZ

Oscillators Overview

The ISM97-6251AH-40.000MHZ is a standard crystal oscillator (XO) manufactured by ILSI, operating at a nominal frequency of 40 MHz. It features HCMOS/TTL compatible output logic levels and supports an enable/disable function via a 2.5V control signal. The component utilizes a 4-pin surface-mount package with no lead construction. It operates within a supply voltage range of 2.85 V to 3.15 V, with a nominal rating of 3 V. The device is designed for applications requiring low jitter and non-PLL based clock generation.

Oscillators Feature Summary

• CMOS/TTL compatible logic levels for broad interface integration
• Low jitter performance without PLL-based architecture
• Integrated enable and disable functionality for power management

Oscillators Applications

• Fibre Channel server and storage systems
• SONET/SDH network infrastructure
• 802.11 and Wi-Fi communication modules
• T1/E1 and T3/E3 system clock generation

Oscillators Procurement Notes

Verify the specific suffix codes against official ILSI documentation to confirm exact pinout, tolerance, and packaging specifications. Ensure that the enable/disable control voltage requirements align with the target system's logic levels before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a 40 MHz clock source with HCMOS/TTL outputs is required in a compact surface-mount form factor. Consider the enable/disable feature if dynamic power control is necessary. Verify that the operating temperature range and frequency stability meet the specific environmental constraints of the application design.

Oscillators Part Context

This part belongs to the ISM97 series of ceramic package SMD oscillators from ILSI. The series is characterized by low jitter and non-PLL based output designs. These components are engineered for high-reliability timing applications in telecommunications and data storage environments, offering a robust alternative to traditional through-hole or larger surface-mount oscillators.

Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other ILSI ISM97 series variants only if pin compatibility and electrical parameters match exactly.
