Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the exact enable/disable configuration and voltage tolerance. Ensure the 4-SMD footprint matches the target PCB layout. Cross-reference the part number with the manufacturer's current product status, as availability may vary across distributors.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS clock source is required with active control capabilities. The 4-SMD form factor suits space-constrained designs. Confirm that the 45.185 MHz frequency aligns with the system's timing requirements and that the enable pin logic level is compatible with the controlling microcontroller.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronic Ind. Co., Ltd. The series typically offers various frequencies and voltage options within a small SMD footprint. The 'OE' suffix likely denotes specific operational characteristics or packaging variants defined by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes must match the 45.185 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications before substitution.
