Oscillators Procurement Notes

Verify the specific suffix configuration against the official ILSI part number guide to confirm electrical parameters such as frequency stability and jitter specifications. Ensure the selected variant matches the required output load and duty cycle tolerances for the target application design.

Oscillators Selection Notes

Select this component when a 12 MHz reference with CMOS/TTL outputs is required in a small SMD footprint. Consider the enable pin requirement for power management strategies. Verify that the operating temperature range and supply voltage tolerance align with the system's environmental constraints.

Oscillators Part Context

This model belongs to the ISM92 series of ceramic package SMD oscillators from ILSI. The series is characterized by low jitter performance without PLL-based architectures. It serves as a direct replacement for other 12 MHz XO components in designs requiring precise timing synchronization for high-speed data interfaces.

Oscillators Replacement Considerations

Cross-reference with ISM92-3251EH-12.000MHZ or similar ISM92 variants if different packaging or specific stability grades are needed. Confirm pinout compatibility and voltage levels before substituting with generic 12 MHz oscillators.
