Oscillators Procurement Notes

Verify the specific operating temperature range and frequency stability class against the official ILSI part number guide table, as these parameters vary across the ISM92 series. Confirm that the 3.3 V supply voltage requirement aligns with the target circuit design. Ensure compatibility with lead-free soldering processes if required by environmental regulations. Cross-reference the physical dimensions (3.2 mm x 5.0 mm) with PCB layout constraints to ensure proper footprints are utilized.

Oscillators Selection Notes

Select this component when a standard 50 MHz clock signal is required for high-speed digital interfaces in telecommunications or data storage applications. The non-PLL design offers simplicity and low phase noise characteristics suitable for sensitive timing circuits. Consider the enable pin feature if dynamic power control is necessary. Verify that the HCMOS/TTL output swing matches the input requirements of the downstream logic components to ensure reliable signal integrity.

Oscillators Part Context

This oscillator belongs to the ISM92 series from ILSI America, which comprises ceramic package SMD oscillators designed for various frequency ranges up to 125 MHz. The series is characterized by its compact 3.2 mm x 5.0 mm form factor and compatibility with both HC-MOS and TTL logic families. It serves as a general-purpose clock source for embedded systems requiring precise timing signals in industrial and consumer electronics.

Oscillators Replacement Considerations

Direct substitutes within the same series include models with identical frequency and package but different voltage or temperature ratings, such as ISM92-3251EH-40.000 or ISM92-2455DO-20.000, provided the electrical specifications match the application requirements. Always verify the suffix codes for voltage and temperature variations before substitution.
