ISM95-1251AH-12.000MHZ

Oscillators Overview

The ISM95-1251AH-12.000MHZ is a standard CMOS oscillator manufactured by ILSI, operating at a frequency of 12 MHz. It features a 1.8V supply voltage and supports enable/disable functionality. The component utilizes a crystal base resonator and is housed in a 4-SMD surface-mount package without lead. It operates within a temperature range of -40°C to 85°C, with a maximum supply current of 20mA.

Oscillators Feature Summary

• CMOS output logic levels compatible with standard digital interfaces
• Integrated enable and disable control for power management
• Lead-free processing compliance for environmental standards

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics requiring low-power oscillators

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD footprint matches the PCB layout specifications. Check for any specific RoHS or REACH compliance documentation required by the end product regulations.

Oscillators Selection Notes

Select this model when a 12 MHz clock source is required with a 1.8V operating voltage. Consider the 4-SMD package size for space-constrained designs. Evaluate the ±25 ppm stability if precise timing is critical. Compare against other ILSI series like ISM92 or ISM97 if different voltage levels or jitter specifications are needed.

Oscillators Part Context

This part belongs to the ILSI ISM95 series of standard CMOS oscillators. It shares the same physical package and basic interface characteristics as other variants in the series, such as the ISM95-1251AH-25.000MHZ, differing primarily in the generated frequency. The series is designed for applications requiring reliable, low-power clock signals in compact form factors.

Oscillators Replacement Considerations

Direct substitutes include other ISM95 series parts with identical pinouts and electrical characteristics but different frequencies, provided the system can tolerate the frequency change. Cross-series replacements from other manufacturers require verification of voltage, package, and output logic compatibility.
