Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official part number guide to ensure correct frequency stability, duty cycle tolerance, and package variant. Confirm that the requested unit matches the exact electrical specifications required for the target application circuit. Cross-reference the datasheet revision date to ensure access to the most current technical parameters and pinout definitions before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a compact 4-pin SMD oscillator with HCMOS/TTL outputs is required for high-speed digital interfaces. Ensure the operating temperature range meets the environmental constraints of the end product. Verify that the 12 MHz frequency aligns with the system clock requirements and that the enable/disable functionality is necessary for power management strategies in the design.

Oscillators Part Context

This model belongs to the ISM97 series of ceramic package SMD oscillators manufactured by ILSI America. The series is characterized by its small form factor and compatibility with standard surface-mount assembly processes. These oscillators are engineered to provide stable clock signals for telecommunications and data storage applications requiring precise timing and low phase noise.

Oscillators Replacement Considerations

Direct substitutes include other ISM97 series variants with matching frequencies and packages, such as ISM97-3251BH-12.000MHZ. Verify pinout compatibility and electrical parameter equivalence before substitution.
