• Consumer electronics requiring low-voltage operation
• Embedded systems with space constraints

Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's datasheet to confirm enable/disable functionality and voltage levels. Ensure the 4-SMD footprint matches the PCB layout requirements. Cross-reference the frequency tolerance and load capacitance specifications with the system clock requirements before finalizing procurement.

Oscillators Selection Notes

Select this component when a 1.8V supply is available and an enable pin is required for power management. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the small form factor if board space is limited. Verify that the operating temperature range meets the application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'OE' suffix likely denotes specific operational characteristics such as enable control, distinguishing it from other variants in the same package family.

Oscillators Replacement Considerations

Check for exact frequency match and compatible supply voltage. Verify package dimensions and pinout compatibility. Ensure output type (LVCMOS) and enable functionality are supported by potential substitutes.
