Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 14.31818 MHz specification. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the enable/disable pin configuration is compatible with the system logic levels. Check package orientation markings against board layout requirements. Validate RoHS compliance status for environmental regulations.

Oscillators Selection Notes

Select this component when a precise 14.31818 MHz timing source is required with low power consumption capabilities. The 1.8V operation suits modern low-voltage digital logic families. The enable feature allows for dynamic power saving in battery-operated devices. Consider the ±25ppm stability requirement against system jitter tolerance. Evaluate the SMD footprint compatibility during PCB design phase.

Oscillators Part Context

This part belongs to the ILSI ISM97 series of standard CMOS oscillators. The series offers various frequencies and voltage options, including 3.3V variants like the ISM97-3251AH. The ISM97-1251AH specifically denotes the 1.8V version in the 3.2x2.5mm package family. It serves as a direct replacement for other industry-standard oscillators requiring identical electrical parameters.

Oscillators Replacement Considerations

The ISM97-3251AH-14.31818MHZ is a confirmed substitute offering identical frequency but operating at 3.3V instead of 1.8V. Verify voltage level compatibility before substitution. Other ISM97 series parts share the same package but differ in frequency or voltage.
