ISM97-1251AH-33.333MHZ

Oscillators Overview

The ILSI ISM97-1251AH-33.333MHZ is a standard clock oscillator operating at 33.333 MHz with a CMOS output interface. It functions as an XO (Crystal Oscillator) powered by a 1.8V supply voltage. The component supports Enable/Disable control functionality and is designed for surface mount installation in a 4-SMD, No Lead package. Key electrical specifications include a maximum supply current of 20mA and a frequency stability of ±25ppm. The device is rated for an operating temperature range of -40°C to +85°C.

Oscillators Feature Summary

• CMOS output signal generation
• Enable/Disable control capability
• Surface mount packaging

Oscillators Applications

• Standard clock signal distribution
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific suffix 'AH' against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure the 1.8V supply requirement aligns with the target system design. Confirm RoHS compliance status through the latest production documentation before integration into final assemblies.

Oscillators Selection Notes

Select this component when a precise 33.333 MHz reference is required for low-voltage digital logic. The ±25ppm stability suits general timing applications rather than high-precision RF systems. Consider the 20mA current draw for power budget calculations and verify thermal performance within the specified -40°C to +85°C operational window.

Oscillators Part Context

This part belongs to the ISM97 series of standard oscillators from ILSI. The series offers various frequencies with consistent 1.8V operation and CMOS outputs. Similar models like the ISM97-1251AH-50.000MHZ share identical physical and electrical characteristics except for the nominal frequency output.

Oscillators Replacement Considerations

Direct substitutes must match the 33.333 MHz frequency, 1.8V supply, CMOS output, and 4-SMD package. Verify pin configuration compatibility before swapping. Cross-reference with other manufacturers offering equivalent standard oscillators if availability is constrained.
