Oscillators Procurement Notes

Verify the specific suffix 'AH' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 3.3V supply rail is stable within the specified tolerance to maintain the stated frequency stability. Confirm that the 4-SMD no-lead package footprint aligns with your PCB layout guidelines before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator with enable control is required for 3.3V logic systems. The 16 MHz frequency suits common microcontroller and processor clock inputs. Consider the ±25ppm stability specification against your system's jitter budget and timing accuracy needs compared to higher-grade alternatives.

Oscillators Part Context

This part belongs to the ISM97 series of standard oscillators from ILSI. The series offers various frequencies and packages, with the AH suffix typically denoting specific electrical or packaging variations within the product line. It serves as a fundamental timing source for electronic assemblies requiring precise clock generation in a compact form factor.

Oscillators Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any replacement matches the 16 MHz frequency, 3.3V supply, CMOS output, and 4-SMD package dimensions. Ensure equivalent enable/disable functionality and stability specifications are maintained to avoid redesign.
