Oscillators Procurement Notes

Verify the specific suffix against the manufacturer's current part number guide to confirm exact frequency tolerance and temperature range specifications. Ensure the ordering code matches the required output load and enable pin configuration. Cross-reference the datasheet revision date to validate environmental compliance and tape/reel packaging details before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a compact 2.5x3.2 mm ceramic oscillator with TTL/HC-MOS outputs is required. It is suitable for applications demanding low jitter and non-PLL stability. Consider the enable/disable capability if power conservation during idle states is necessary. Verify that the operating temperature range meets the specific environmental constraints of the target electronic assembly.

Oscillators Part Context

This model belongs to the ISM97 series of standard crystal oscillators (XO). The series is characterized by its small ceramic surface-mount package and compatibility with both TTL and HC-MOS logic families. It serves as a general-purpose clock source for digital circuits requiring precise timing signals in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes within the same series include ISM97-3351AH variants with different frequency suffixes, such as ISM97-3351AH-8.0000 or ISM97-3351AH-60.000. These parts share identical physical dimensions and electrical interface characteristics, allowing for potential pin-compatible upgrades or frequency adjustments in existing designs.
