Oscillators Procurement Notes

Verify that the specific suffix AH corresponds to the required packaging format and tolerance specifications for your application. Confirm that the 3.3V supply requirement aligns with your system power rails. Ensure ESD handling procedures are followed during installation due to the sensitivity of the CMOS output stage. Cross-reference the pinout diagram with your PCB layout to guarantee correct orientation of the 4-SMD no-lead package.

Oscillators Selection Notes

Select this component when a 16 MHz reference signal with TTL/HCMOS compatibility is required in a small form factor. It is suitable for designs needing precise clock generation without the complexity of PLL circuits. Consider the thermal operating range and stability requirements against the datasheet specifications. Verify that the load capacitance matches your circuit design to ensure accurate frequency performance.

Oscillators Part Context

This part belongs to the ISM92 series of surface-mount oscillators manufactured by ILSI America. The series offers various frequency options in a standardized 3.2 mm x 5.0 mm ceramic package. These oscillators are engineered for high reliability in telecommunications and data storage applications, providing stable clock signals with low phase noise characteristics across the operating temperature range.

Oscillators Replacement Considerations

Direct substitutes include other ISM92 series variants with identical pinouts and electrical characteristics but different frequencies or supply voltages. Verify mechanical footprint compatibility before replacing with generic SMD oscillators. Ensure logical level compatibility (HCMOS/TTL) is maintained if interfacing with existing digital logic circuits.
