Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 33.333 MHz operation. Confirm that the 1.8V supply voltage aligns with the target system logic levels. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout requirements. Check that the ±25 ppm stability meets the application's timing tolerance needs. Validate the enable/disable pin configuration against the control logic design.

Oscillators Selection Notes

Select this component when a standard CMOS output waveform is required for digital interfacing. Consider the 1.8V supply constraint and the need for an enable function. Evaluate the ±25 ppm stability against system jitter requirements. Compare the 4-SMD package size against available board space. Verify compatibility with the -40°C to +85°C operating environment.

Oscillators Part Context

This model belongs to the ISM95 series of standard oscillators from ILSI. The series offers various frequencies including 24 MHz, 25 MHz, 50 MHz, 60 MHz, and 33.333 MHz variants. All models share similar electrical characteristics and package dimensions, differing primarily in the output frequency determined by the crystal resonator.

Oscillators Replacement Considerations

Direct substitutes include other ISM95 series variants such as ISM95-1251AH-24.000MHZ or ISM95-1251AH-50.000MHZ if frequency adjustment is permissible. Cross-brand replacements require matching CMOS output type, 1.8V supply, 4-SMD package, and comparable stability metrics.
