Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet for the exact suffix configuration. Confirm that the 4-SMD no-lead package dimensions match the target PCB footprint requirements. Ensure the 3.3V supply voltage aligns with the system power architecture before integration.

Oscillators Selection Notes

Select this component when a stable 50 MHz reference is required in a compact surface-mount form factor. The enable/disable feature allows for power management optimization in battery-operated or low-power designs. Verify compatibility with downstream CMOS logic inputs regarding voltage levels and drive strength specifications.

Oscillators Part Context

This part belongs to the ISM95 series of standard oscillators from ILSI. The series provides various frequencies and package options for embedded applications. The 'AH' suffix typically denotes specific performance characteristics such as stability and package type within the product line.

Oscillators Replacement Considerations

Direct substitutes must match the 50 MHz frequency, 3.3V supply, and 4-SMD no-lead package. Check pinout compatibility and electrical parameters like jitter and stability if cross-referencing with other manufacturers' HCMOS/TTL oscillators.
