ISM92-3251AH-24.000MHZ

Oscillators Overview

The ISM92-3251AH-24.000MHZ is a surface-mount ceramic package clock oscillator manufactured by ILSI America. It operates at a nominal frequency of 24 MHz with a standard HCMOS/TTL output type. The device supports a supply voltage range of 2.565 V to 2.835 V, with a nominal value of 2.7 V. It features an enable/disable control function and utilizes a 4-SMD, no-lead package configuration measuring 5.0 mm x 3.2 mm. The component is lead-free compliant and RoHS certified.

Oscillators Feature Summary

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

Oscillators Applications

• Fibre Channel server and storage systems
• SONET/SDH network infrastructure
• T1/E1 and T3/E3 system clocking

Oscillators Procurement Notes

Verify the specific suffix 'AH' against official ILSI documentation to confirm the exact electrical tolerances and enable pin configuration. Ensure the procurement source provides valid RoHS compliance certificates and lead-free processing verification. Cross-reference the 4-SMD no-lead package dimensions with the manufacturer's mechanical drawing to guarantee board layout compatibility.

Oscillators Selection Notes

Select this component when a 24 MHz reference signal with HCMOS or TTL output levels is required for high-speed digital interfaces. The non-PLL design offers specific jitter characteristics suitable for applications where phase noise profiles differ from PLL-generated clocks. Consider the 2.7 V nominal supply requirement and the enable/disable feature for system power sequencing strategies.

Oscillators Part Context

This part belongs to the ISM92 series of ceramic SMD oscillators from ILSI America. The series is characterized by low jitter and CMOS/TTL compatibility. Similar parts in the series include variants with different frequencies such as 20 MHz or 25 MHz, and different package sizes like the 2.0 mm x 2.5 mm option found in the ISM95 series.

Oscillators Replacement Considerations

Direct substitutes within the same series include ISM92-2455DO-20.000MHZ for frequency variations or ISM95-3251AH-25.000MHZ for package size differences. Verify that any replacement maintains the 4-SMD no-lead footprint and compatible logic voltage levels.
