Oscillators Procurement Notes

Verify the specific frequency tolerance and temperature stability requirements against the official ILSI datasheet for the ISM95-1251AH series. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead footprint matches the PCB layout constraints. Check for RoHS compliance status if required by project specifications.

Oscillators Selection Notes

Select this component when a low-profile, 1.8V CMOS oscillator with enable control is required. The 2.0mm x 2.5mm package suits space-constrained designs. Verify compatibility with HC-MOS/TTL input thresholds of downstream logic. Consider thermal performance within the -40°C to 85°C operating range for environmental suitability.

Oscillators Part Context

This part belongs to the ISM95 series of SMD oscillators from ILSI. The series typically offers various frequencies and voltage options in compact ceramic packages. The ISM95-1251AH variant specifically targets 1.8V applications with standard CMOS outputs, distinguishing it from higher voltage or different package size variants within the same product line.

Oscillators Replacement Considerations

Direct substitutes must match the 1 MHz frequency, 1.8V supply, 4-SMD no-lead package, and CMOS output type. Cross-reference with other manufacturers offering equivalent small-form-factor oscillators with enable pins. Verify pinout compatibility and electrical characteristics before substitution.
