Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the exact supply voltage, frequency tolerance, and package variant. Ensure the selected part number matches the required enable/disable functionality and operating temperature range. Confirm compliance with RoHS standards and lead-free processing requirements before procurement.

Oscillators Selection Notes

Select this component when a 50 MHz reference signal with HCMOS or TTL output levels is required. Consider the 5x7mm ceramic footprint for space-constrained designs. Verify that the 3.3V supply voltage aligns with the target system power rails and that the enable pin logic is compatible with the controlling microcontroller.

Oscillators Part Context

This model belongs to the ISM91 series of ceramic surface-mount oscillators from ILSI. The series provides stable clock signals for high-speed digital applications. The specific designation indicates a 50 MHz frequency operation within the standard HCMOS/TTL output family.

Oscillators Replacement Considerations

Cross-reference with other ISM91 series variants for different frequencies or voltages. Check manufacturer substitution lists for updated packages or enhanced performance versions within the same product line.
