Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm enable/disable functionality and pinout configuration. Ensure the 1.8V supply requirement aligns with target system power rails. Confirm the 4-SMD package dimensions match PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a 75.655 MHz reference is required with low-power consumption. The enable/disable feature allows for power management in battery-operated devices. Verify that the LVCMOS output swing is compatible with downstream logic levels. Consider thermal performance within the specified operating temperature range during integration.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The -OE suffix typically denotes specific operational characteristics such as enable control. This model represents a mid-frequency option within the product line.

Replacement Considerations

Check Mercury Electronics datasheets for direct substitutes with identical frequency and package. Verify electrical compatibility with alternative vendors' parts. Ensure pin-to-pin compatibility if swapping manufacturers. Confirm that enable/disable logic polarity matches existing design requirements.
